Introducing Craves’s Giant Barn Owl!

I recently received a great honor: a new (albeit extinct) species of owl was named after me. Craves’s Giant Barn Owl (Tyto cravesae) was recently described based on fossils discovered in Cuba by my great friend William Suárez. The bird was described in a recent paper published in the journal Zootaxa, Systematics and distribution of the giant fossil barn owls of the West Indies (Aves: Strigiformes: Tytonidae) by William, formerly a curator of the National Museum of Natural History and now living in the U.S., and Storrs L. Olson of the Smithsonian Institution.

The bones of this owl were discovered in a cave complex in Cuba by William in 1998, and subsequently in several other locations in Cuba. The paper reviews and revises previously described species, with two of those being synonymized with two others. Thus Tyto cravesae becomes the fourth extinct giant barn owl described from the West Indies.

These owls were all larger than Tyto alba, the common Barn Owl found across much of the world today, including in North America. Based on the bones found, Craves's Giant Barn Owl was likely somewhat larger than a Great Horned Owl. There were also even larger prehistoric owls in Cuba in the genus Ornimegalonyx, estimated to be a meter or more tall!

The cave deposits date from sometime in the late Pleistocene (the epoch ranging from 2.5 million to around 12,000 years ago), and include the bones of prey items.  Craves's Giant Barn Owl fed on large rodents and small mammals. The lack of other predators on mammals besides giant birds in the West Indies is the main reason these owls evolved into such large forms. "My" owl probably often preyed upon hutias, a group of rodents endemic to the Caribbean region; one species identified with the Tyto cravesae bones was that of the Cuban or Desmarest's Hutia (Capromys pilorides). The giant Antillean owls probably became extinct due to the loss of their prey species.

I got to know William during several U.S. licensed trips to Cuba in the early 2000s in which I assisted with and lead bird surveys throughout the island. William is a leading authority on Caribbean birds and mammals, both living and extinct. He has written or co-authored many papers as well as a book, and described and named several other new genera and species of birds. Over the years, we kept in continuous touch both as friends and colleagues.

In the paper describing Tyto cravesae, the section describing the naming of the species states: "After Julie Craves, of the University of Michigan-Dearborn for her dedication to avian conservation and her boundless appreciation of Cuban friends and birds." 

No matter what he has encountered, William has persevered with remarkable optimism and good humor. His strength and accomplishments have been a continual source of inspiration to me.  I am incredibly honored that he chose to name this new species of owl after me, when the true honor has been mine, simply having the opportunity to be his friend.

Read more at the BirdWatching Magazine blog, where William and I responded to questions from editor Chuck Hagner. In 2002, I also wrote an article for the magazine, The Birds of Cuba. In 2003, colleague Kim Hall and I published a paper on some of the survey's findings in the Journal of Caribbean Ornithology, Notable bird sightings from Cuba, winters 2002 and 2003.

Silent Spring after 50 years

Have we learned our lesson?

Fifty years ago this month the important book Silent Spring by Rachel Carson was published. This book warned about the lethal and persistent effects of the pesticide DDT. This book, while in some ways outdated, remains a classic not only for its role in inspiring environmental stewardship, but also because although DDT has been banned in the United States, as a society we still enthusiastically embrace a whole suite of chemicals that end up in our air, water, and soil (and ultimately in animals and ourselves). And we still tend to trust that they are perfectly safe.

In fact, testing of pesticides and other chemicals is focused specifically on active ingredients used in certain amounts and circumstances. Many people use chemicals in ways not intended by the manufacturers, in amounts beyond recommended volumes, in combination with other chemicals, and when none are really needed in the first place. Aside from the risks of these types of applications, we further know very little about the components of this toxic soup interact with each other and the environment.

An excellent example is the American obsession with cosmetic lawn and garden chemicals. I don't want to get too soap-boxy here, but I can tell you two things. First, you can have a nice lawn (if you must) and garden without the use of any chemicals. I've done this my whole life. Second, one of the best things you can do for birds (your pets, the ecosystem, and yourself) in your area is to quit using all chemicals in your yard, because they do harm birds.

I see the effects of "safe" lawn chemicals every year on common birds. I have held emaciated robins in my hands as they had seizures and died, and looked up from their lifeless bodies to rest my gaze upon those little signs indicating an expanse of grass was sprayed with some concoction. Without direct toxicology tests, I can't honestly say lawn chemical exposure was the direct cause of these deaths. I do know that robins can't read to keep off the grass, that their symptoms are typical of exposure, and it is far too common an occurrence to not at least suspect that some combination of chemical exposure is to blame.

On this anniversary of the publication of Silent Spring, I encourage you to read or re-read this book and related material. We are in an age where enough data is available for us to be truly informed and where our actions can make a real difference. Unfortunately, we are also at a point where we are distrustful of science, and often bombarded with conflicting messages from special interest groups. I don't have a horse in this race, except my love for the natural world. Here are my recommendations:

An excellent overview of the context and impact of Silent Spring can be found at the Pop History Dig website: Power in the Pen: Silent Spring 1962. The New York Times Magazine also recently published How Silent Spring ignited the environmental movement.

The book itself, Silent Spring (Kindle edition here), as well as a new biography of Rachel Carson, On a Farther Shore: The Life and Legacy of Rachel Carson (Kindle here).

I also strongly recommend Our Stolen Future, which further explores synthetic chemicals in the environment.

There are many excellent sites on thee continued risk of chemicals many of us continue to use regularly. The non-profit Environmental and Human Health published a report very worth reading: Risks from Lawn Care Pesticides. The organization Beyond Pesticides has extensive information about pesticide issues, risks, and alternatives.

Chimney Swift tower!

Chimney Swifts are probably familiar to most people: twittering "flying cigars" in our summer skies, feeding on aerial insects. Like other species of swifts, Chimney Swifts spend most of their time in the air, even mating and bathing on the wing. Chimney Swifts breed across much of eastern North America, and winter in the Amazon basin of northwestern South America.

Patient observers might note individual birds disappearing into tall chimneys during the breeding season. Chimney Swifts make a small nest of twigs, held together and glued with saliva to the inside wall of a chimney-like structure. Only one pair will nest per chimney or structure, but there may also be a few non-breeding swifts, some of which (usually young from a past year) may "help" the breeding swifts feed the young in the nest. Chimney Swifts use chimneys and similar structures outside the breeding season, too. During migration, especially in fall, many hundreds of swifts might use large chimneys to roost in overnight.

Prior to European settlement of North America, Chimney Swifts used hollow trees, caves, and narrow chasms. Their populations probably increased with the availability of human structures for nesting and roosting. However, in recent years Chimney Swift populations have undergone a dramatic decrease. In the U.S., this decline has been about 2.4% per year since the early 1980s; in Michigan the rate has been -1.5% annually (based on Breeding Bird Survey data).
 
Several factors are probably at play. Most important is a decrease in aerial insect prey, likely due to pesticide use, habitat loss, and a changing climate. Other species of birds that rely on aerial insects, such as Common Nighthawks and swallows, are also on the decline. Add to this a special problem for Chimney Swifts: chimney design has changed in modern times, with many chimneys being too narrow, or covered or lined, for swifts to use.

This has led many organizations and individuals to create artificial Chimney Swift nesting structures. This spring, Stephen Lisius constructed and erected one of these excellent towers behind the Environmental Interpretive Center as his Eagle Scout project.

Stephen designed the tower according to plans similar to the graphic above, which is available in the Chimney Swift Nest Site Research Project Information Handout (PDF). The tower was constructed off-site, and then erected onto a sturdy foundation that had been put in place the week before. Here's the tower in place:

The outside of the tower will be finished soon with weatherization wrap and shingles. Stephen also plans to install a camera, so if/when swifts discover and use the tower, we can see what's going on. We may have to be very patient -- some towers go for years before they are used. I'll keep you posted!

If you are interested in learning more about these towers or even seeing if you'd like to make one yourself, the book Chimney Swift Towers: New Habitat for America's Mysterious Birds is the go-to guide.


Meanwhile, you might consider one of the swift monitoring projects. The program called Swift Night Out is done each fall in the U.S. Bird Studies Canada has initiated a citizen swift monitoring program as well.

Moth program results

Our moth program with field guide author Seabrooke Leckie was a great success! We were a bit worried about the cool weather, but Seabrooke explained that many moth species overwinter as adults (rather than eggs, caterpillars, or pupae/cocoons). These cold-hardy species will fly in temperatures cooler than we were experiencing (in the mid-50s).

Seabrooke arrived in late afternoon, and we set up several sheets with different types of light (black light, mercury vapor). Moths are attracted to the lights and land on the sheets.

One of the sheet/light set ups.

We also soaked some rope in a mixture of red wine and brown sugar, and hung them out to attract species that feed on nectar and sap (many adult moths, however, do not eat at all). This mix should really be allowed to ferment, so we didn't have luck with that.

Stinky, sticky wine rope hanging from wood shed.

Seabrooke started out with a short presentation focusing on moths in the environment.

Then our group of about 30 people made the rounds of the sheets and collected moths in clear pill bottles. These were brought back into the building where Seabrooke identified them.

Seabrooke also helped my husband Darrin identify some photographs he had taken the last few years.

 
Our friend Don Sherwood has been raising silkworm moths. He brought along this Luna Moth to show everybody. I think this is probably one of the most beautiful moths in the world!

Here is our list of moths that came to the lights, with links to the species or genus at BugGuide, a great online resource for insect identification. Some very tiny moths ("micromoths") were only identified to genus.

The Curve-toothed Geometer. We released
all the moths at the end of the night.

1. Unicorn Prominent (Schizura unicornus)
2. The Gem (Orthonama obstiptata)
3. Celery Leaftier (Udea rubigalis)
4. Palmerworm Moth (Dichomeris ligulella)
5. Featherduster Agonopterix (Agonopterix pulvipennella)
6. Confused Woodgrain (Morrisonia confusa)
7. Acleris sp.
8. Common Acleris (Acleris subnivana)
9. The White-Speck/Armyworm (Mythimna unipuncta)
10. Dusky Groundling (Condica vecors)
11. Olive-and-black Carpet (Acasis viridata)
12. Epinotia sp.
13. Eupithica sp.
14. Bent-line Carpet (Costaconvexa centrostrigaria)
15. Curve-toothed Geometer (Eutrapela clemataria)
16. Red-banded Leafroller (Argyrotaenia velutinana)
17. Gray-banded Leafroller (Argyrotaenia mariana)

There were also a couple of "get-aways" and some that flew near the sheets that we didn't catch.

Thank you Seabrooke for an excellent evening!

Julie Craves and Seabrooke Leckie.

Moth program with field guide author Seabrooke Leckie

It's with great anticipation that I announce an upcoming program, a joint effort between RRBO and the University of Michigan-Dearborn Environmental Interpretive Center. Seabrooke Leckie, co-author of the new Peterson Field Guide to Moths of Northeastern North America will be visiting on Sunday, April 29, 2012. She will be giving an informal program on moths, and will be setting up her nocturnal moth-attracting gear in the campus natural area to see what is around. Late April can be fairly early for a wide variety of moths at this latitude, but with the exceptionally warm spring, it's hard to know what to expect! Let's hope the weather doesn't turn too fickle.

I can't wait to see the new field guide. It will be released shortly before the program, and Seabrooke will be happy to sign your copy (she will have some available for purchase, or you can pre-order at Amazon). This book is sorely needed, and you can read more about the story behind it, what it will include, and see some sample plates at Seabrooke's web site.

Plus, I'm really looking forward to finally meeting Seabrooke in person. I first became aware of her through her former work as a bird bander at Tommy Thompson Park Bird Research Station in Toronto. They banded a Ruby-crowned Kinglet in 2003 that I recaptured here on campus in 2005. Since then, she and I have kept in touch through our blogs and social networking. Seven years is like forever in the ephemeral world of the Internet, so it feels like we have been friends a long time. I'm eager to met her ITRW ("in the real world"), as the kids say these days.

The program will take place from 8 PM until midnight at the campus EIC.

The program is free, and children must be at least 12 years of age to attend. We ask that you please RSVP by dropping us a note; you can do so by filling out the contact form on the RRBO web site.

RRBO is 20 years old!

The Rouge River Bird Observatory banded its first bird -- a Black-capped Chickadee -- in 1992. Since then, we've banded over 33,000 more birds, conducted thousands of bird surveys, compiled hundreds of thousands of bird records, participated in numerous cooperative research projects, trained dozens of field volunteers...our list of accomplishments goes on.

For our 20th anniversary, we'll be starting an email newsletter to share a look back at some highlights of the past twenty years, and look forward to our future. If we don't have your email address, please sign up for our newsletter at this link. I'll be putting out our first issue later this month.

We thought it might be fun to spruce up the RRBO logo to reflect our anniversary. The original depiction of the bird with two leaves is from an architectural detail in Fair Lane, Henry Ford's estate; we chose it to reflect the historic nature of our study site. You may see this little bird carrying a banner acknowledging RRBO's 20 years of bird conservation. It will certainly be sitting on a branch that now has three leaves, representing our growth and the start of our third decade.

Given that RRBO is donor-supported, all our successes have been yours as well. We can all celebrate together!

Former RRBO bander's research in NYT

Julie Jedlicka was an RRBO bander from 2000 to 2003, when she was a graduate student at the University of Michigan-Ann Arbor. She went on to receive her Ph.D at the University of California, Santa Cruz. She is now at the University of California, Berkeley on an NSF Postdoctoral Fellowship. Her research focuses on ecosystem services and avian conservation potential in northern California vineyards.

Julie and I have kept in touch throughout her academic career, and it has always been exciting to see her accomplishments accumulate. She has published a number of papers, and her most recent one -- Avian conservation practices strengthen ecosystem services in California vineyards -- was featured in the New York Times!

I like to think that RRBO had a small part in her success. But I know it is because Julie is a dedicated, creative scientist. Way to go, Julie!

Barred Owl in Dearborn

[2017 update at bottom of post]

I get a fair number of calls to help rescue birds from various situations, often inside buildings. Usually they are very common species (European Starlings, in particular, seem to have a knack for falling down chimneys). Often there isn't much I can do but offer advice, which is often sufficient to solve the problem.

Late yesterday afternoon I got a message from Jim Barber at the First Presbyterian Church of Dearborn, directly across the Rouge River from campus. They had a large owl (he thought Great Horned) trapped in the basement boiler room of the church. He was at wits end -- the bird had been there for at least several days and nobody he called was taking any action. The notion of a Great Horned Owl getting down a ventilation shaft seemed pretty unlikely to me, and he told me the room was around 20 by 20 feet with high ceilings. This seemed like a difficult situation, but my curiosity, the plight of the bird, and Jim's frustration compelled me to immediately head up to the church and figure out how I could help.

Within 15 minutes I was looking in the boiler room. Not only was it big, it was cluttered with all sorts of equipment and supplies. This was the part of the room I saw when I walked in:

To the right was the large boiler, and the ceiling went up another 10 feet, criss-crossed with pipes and supports. A large owl did indeed take off from a ceiling beam and fly over to a pipe above the boiler. To my great astonishment it was not a Great Horned Owl (or a Cooper's Hawk, which I sort of expected), but a Barred Owl (Strix varia), a species with only a single record from Dearborn, in 1976 (see history, below).

I decided there were two possibilities for catching the owl. One, with a long-handled net, although with so many obstacles I thought this might result in a lot of chasing around, which would stress the bird. The other was to use a bal-chatri trap, a common way of catching raptors. Bal-chatris are wire traps topped with small nooses made of fishing line. A mouse is placed in the trap, and when the raptor pounces on the trap it gets its talons caught in the nooses. The mouse isn't harmed, and the bird can be quickly released from the nooses. I figured the owl would be very hungry after three days, and this should work pretty well.

After outlining my plan, I called my husband Darrin O'Brien to have him bring a bal-chatri from home as well as a net for back up. I also called my good friend Jim Fowler. Jim has a great deal of experience handling raptors, and also spent 30 years at Greenfield Village as the head of the grounds department, rescuing plenty of birds from buildings. He would bring a long-handled net and a second bal-chatri. I went up to the RRBO banding lab on campus to fetch my banding gear.

When we all reconvened at the church, a member of the Michigan Humane Society wildlife department had shown up. He and the church employees had ambushed the owl and had it wrapped in a shirt, saving us a great deal of trouble. We took the owl from him, and after one loud screech, it settled down and stared up at Jim, who held it while we checked the bird's condition and I measured the wing.

Considering its ordeal, the owl was in great shape. It had some fat, and had no injuries or even broken feathers. Jim Barber and his co-worker Jamie told us there were certainly mice in the boiler room (and they also put out water for the owl), so we can only assume it probably ate while holed up.

Darrin took the bird so we could band it.

I let Jim Fowler do the honors. While it looks like Jim's nose might be in danger here, it's really the talons you have to worry about. Sure enough, it did grab Jim's thumb at one point, drawing blood.

Outside the breeding season, Barred Owls cannot be sexed, so we don't know if the owl is a male or female. But looking at the color, shape, and wear of the wing and tail feathers can help determine age.

All the wing feathers and their coverts (the row of feathers covering the bases of wing feathers) are quite uniform in color and wear, which indicates that this is a hatching-year (HY) bird. The outer six wing feathers (primaries) are slightly more worn that the inner four, but that might be due to flying around a room full of close objects and brushing against them. Further, at no age would we really expect all the inner primaries to be replaced and the outer primaries retained. The shape of the primary coverts is rounded, with the pale areas more round than block-shaped, also an indication of HY.

In the photo above, we can count the number of pale bars on primary number 9, the second feather from the outside. Five bars are visible, not counting the pale tip. In the first set of wing feathers on a Barred Owl, p9 will have 4 to 5 bars; there will be only 3 to 4 bars on it after it is molted. This feather might be molted in the owl's second fall, or not until the third fall. This owl was not actively molting any wing or tail feathers. If it was older than HY, it should have been molting some feathers, or there should have been some new wing feathers that looked different -- less worn with narrower bars spaced further apart.

The photo above not only proves I was actually present at this event, but also shows the pointed, whitish tips of the tail feathers. These are the first tail feathers, which will probably not be replaced until the bird's third fall molt, after which they will have darker, blunter tips and narrower bars. All of this leads to my conclusion that this is an HY bird. By October 10, we would expect that any flight feather molt would be nearly or fully complete, so if it were an older bird, we would see the contrast in old and new feathers discussed above. It's always tricky determining the age of a bird with which you have no experience, so I'm happy to take any corroboration or contradiction in the comments!

We walked to the edge of the parking lot to release the owl. It took flight and landed in a tree, shook itself, gave us one last look, and took off toward the Rouge River and UM-Dearborn campus. 

Barred Owls in Wayne County

According to historical accounts, Barred Owls nested in Wayne County until about 1910, after which they were apparently extirpated, being hunted and pushed out by agricultural and urban development. The next record I found was a report from the UM-Dearborn campus on 12 May 1971. I was unable to confirm the veracity of this record, but it was by a reliable observer. The only reliable report I have had from Dearborn is a bird seen on 7 April 1976 by Gary Hutman on land that is now the TPC Golf Course. Over a decade passed before a report came from Grosse Ile on 27 December 1987. In 1994, one was seen at Lake Erie Metropark by my husband Darrin on 17 September.

In recent years, Wayne County reports have become more frequent. Daryl Asprey found one at Crosswinds Marsh (phase 1) on 6 December 2003. When RRBO was coordinating the breeding bird atlas work for the county, one or two were reported calling in a wooded area in Canton Township from 2004-2006; we were never able to confirm nesting. Several years ago, a pair took up residence at Oakwoods Metropark, first heard calling by Daryl Asprey on 23 February 2007. Feel free to add any further records in the comments.

Thanks to everybody who participated in this rescue. Good luck to the owl, and to the guys who I understand will be on the roof of the church today, closing off a certain ventilation shaft...

Update: I had a report of a Barred Owl being heard at the far north end of campus on 23 April 2017.   

More shade coffee birds and banding: part 2

In my last post I outlined the first portion of my recent trip to Nicaragua. Here is the next installment.

Part 2: Finca El Jaguar

In 2009, during our brief stopover in Managua, Nicaragua, my husband and I met Georges and Liliana Duriaux-Chavarría, the owners of El Jaguar, a fantastic cloud forest reserve and coffee farm near Jinotega in the north-central highlands of Nicaragua. We were immediately taken by both their charm and their dedication to bird conservation. There was no question we would visit them on our next trip to Nicaragua.

El Jaguar consists of about 240 acres, of which 80% is protected cloud forest reserve. This is beautiful old-growth forest with towering trees and thick multi-story growth.

Around 50 acres is coffee (in the foreground above, forest beyond). The coffee areas are broken up into plots separated or connected by forest or natural habitat patches. The coffee itself is grown among banana and other trees, but is not considered heavily shaded. This is because at an elevation of 4300 feet, the farm is covered by misty clouds part of nearly every day. The clouds provide the "shade" and the coffee would suffer from not enough light and a variety of fungal diseases if there were lots of trees planted with the coffee. So while El Jaguar does not qualify for Smithsonian Bird-Friendly certification, they are Rainforest Alliance certified.

Over 270 bird species have been recorded at El Jaguar (we saw about 80 in our few days there). More than 50 are Neotropical migrants (those that primarily breed in the U.S. and Canada and winter in the tropics). This includes an amazing 27 species of "our" warblers -- Golden-winged Warbler, the endangered Golden-cheeked Warbler, and the Cerulean Warbler among them. Due to this rich bird life, El Jaguar was designated as an Important Bird Area by BirdLife International in 2006.

Two winter bird banding stations are run by Georges and Lili at El Jaguar, one in the primary forest, one in the coffee area. Since 2009, El Jaguar has also collaborated with the Golden-winged Warbler Working Group to do regional surveys for this declining North American-breeding warbler. A similar project, the International Wood Thrush Conservation Alliance, is now being launched to benefit the Wood Thrush, and El Jaguar participated in the first workshop.

Wood Thrushes are one of the most common North American-breeding migrants found wintering at El Jaguar. Here is one captured in the nets at the coffee banding station. As part of the working group project, a unique combination of color bands is put on each Wood Thrush so that individuals can be identified without having to recapture them.

This species has declined an estimated 50% over its broad breeding range since the late 1970s. It is evident to us, having traveled in the Neotropics, that Wood Thrushes require mature forests in the winter. The remarkable forests at El Jaguar by far had the most Wood Thrushes we've seen in our travels. The banding program at El Jaguar (and Finca Esperanza Verde) has shown that individual Wood Thrushes return to the same places each winter. Further studies with new technology indicate that there is strong connectivity between particular nesting regions and specific wintering regions. Since RRBO has a history of working with Wood Thrushes, we are anxious to get involved in this conservation effort seeking to understand the linkages with breeding and wintering areas, and factors important to their survival.

If all that work isn't enough, in 2010, Georges and Lili received a Neotropical Migratory Bird Conservation Act grant, through the US Fish and Wildlife Service and matched by the American Bird Conservancy. This grant will assist El Jaguar in reforesting neighboring farms and help community coffee farmers work towards certifying their coffee with Rainforest Alliance. The photo above shows the native tree nursery that is part of this project. Within the next few years, El Jaguar will have raised and distributed over 20,000 trees!

Wilson's Warblers are also amazingly common there. We see them in most coffee farms we visit, and they are one of the few North American migrants that will actually feed in the coffee trees themselves.

Of course, we always like seeing the tropical resident birds. Georges and Lili are now starting a program where they will band throughout the year in order to gather the same type of important survivorship data on resident species.

As always, I like seeing the tropical cousins of the thrushes that I study here at RRBO. Here is an Orange-billed Nightingale-thrush (Catharus aurantiirostris) getting measured.

Quail-doves are notoriously hard to see. This White-faced Quail-dove (Geotrygon albifacies) was captured in the forest nets. Due to the efforts of Georges and Lili, and their son Jean-Yves, to educate the surrounding community, elusive forest birds that are typically scarce because they are hunted are much more common and relatively easy to see at El Jaguar. On the short trail behind our cabin, we saw Violaceous and White-faced Quail-doves (Geotrygon albifacies), and had drop-dead looks at a strolling Little Tinamou (Crypturellus soui) and Highland Guans (Penelopina nigra).

In fact, the guans actually come to feed with the chickens! So do a few Gray-necked Wood-rails (Aramides cajanea).

We didn't do as much hands-on banding at El Jaguar as at Finca Esperanza Verde. They use a different protocol at El Jaguar, and while I am familiar with all the extra measurements they take, the young Nicaraguans who help Georges and Lili could process birds way faster.

Hopefully, I came in handy interpreting the banding and conservation projects to this group that came for a visit.

In trying to make ourselves useful, we also spent time working on putting together a dragonfly list for the property.

We only brought one net, so Darrin did all the catch-and-release. I just posed with the net, but did a lot of ID work.

We were able to find and identify over a dozen species, including this very gorgeous Rhionaeschna jalapensis.

We also photographed and identified over two dozen butterfly species, many of which were new for the El Jaguar list.

We took perhaps eight photos of clearwinged butterflies, which turned out to represent seven different species and several families! This is Greta morgane oto.

We are still working on compiling our lists for Georges and Lili (and then could use a vacation from our vacation). It was a productive trip, and if anybody is interested in the logistics of travel to Nicaragua or El Jaguar, feel free to drop me a line. Here are a few links that may be of interest as well:

• The El Jaguar web site
• My more coffee-centric post at Coffee & Conservation, with more photos!
• An interview with Georges via Rainforest Alliance
• A review of El Jaguar coffee from a couple of years ago at Coffee & Conservation (the new crop will be available this spring at Whole Foods as part of one of their blends; I'll keep everyone posted)

Thank you Georges, Lili, and Jean-Yves!

More shade coffee birds and banding: part 1

Readers will recall that my husband Darrin O'Brien and I like to do "working" vacations, where we travel to Latin American countries to do bird banding, bird surveys, and/or insect survey work. Usually, this involves work on coffee farms, as coffee grown in a sustainable manner is critical to "our" migrant birds, and therefore a topic of great importance to me. Last year we went to west-central Mexico, and in 2009 it was Nicaragua. We returned this year to Nicaragua, taking part both in the same project as 2009, as well as visiting a new location. Here are some highlights of our recent trip. I'll do it in two parts.

Part 1: Finca Esperanza Verde

We started out, as we did in 2009, working with a North Carolina group doing some banding at the shade coffee farm, Finca Esperanza Verde (FEV). A recap of the 2009 trip is here, and more details on the coffee farm itself are here.

In 2009, there were five banders, including us. This year, we were two of three. During banding sessions, we were super-busy! I have a bum knee, so Darrin had the roughest set of nets to check. Nearly everything in coffee country is up or down, and we were at 1150 meters elevation. He often came back to the banding area out of breath. All the nets were in the coffee production area, which at FEV is under a lovely canopy of shade and interspersed with thick forest patches.

We were pretty excited to catch this male Red-capped Manakin (Pipra mentalis) on the first day. Aside from being very cool and crazy-looking, this is the species that "moonwalks" during its courtship display. The next day, we caught a female Long-tailed Manakin (Chiroxiphia linearis). Female manakins are generally dull green, but this family of birds are dependent on forest where they seek out a variety of fruit to eat. Catching them at FEV was evidence of the quality of the forest there.

On the third day, we caught a male Long-tailed Manakin. He was a real crowd-pleaser!

Another blue-colored bird we caught was Blue-black Grosbeak (Cyanocompsa cyanoides). They are a little smaller than our Rose-breasted Grosbeak, and, frankly, didn't seem to bite as much.

One thing we did was take photos of the spread wings of most of the tropical resident birds we processed. Our knowledge of molt strategies and ageing of these birds is limited, and the Institute of Bird Populations is requesting such photos.

This is the wing of an Olivaceous Woodcreeper (Sittasomus griseicapillus), a member of a large family of birds that behave similar to woodpeckers or our Brown Creeper.

And here's the wing of the unrelated Plain Xenops (Xenops minutus). Xenops are also bark-foraging birds that will cling to tree trunks or branches, extracting insects with their wedge-shaped bills. I think the similarity in the wing coloration between these two unrelated birds is quite interesting.

Speaking of cool bills, here is a Stub-tailed Spadebill (Platyrinchus cancrominus)a tiny flycatcher will a nifty, wide, flat bill.

Here's another resident flycatcher with an interesting bill -- a Northern Bentbill (Oncostoma cinereigulare). This was one of several we banded, and two were recaptures from 2008!

Of course, many American migrants rely on shade coffee farms in Latin America, and our interest in this issue is how we got involved in these visits in the first place. The most common North American-breeding migrants at FEV are Wilson's Warbler, Tennessee Warbler, Baltimore Oriole, and Wood Thrush.

Here's another: Louisiana Waterthrush (Parkesia motacilla). This waterthrush was a recapture, and had first been banded at FEV in 2006. That's at least five round trips between the U.S. and Central America. It had also been recaptured a year or so ago, underscoring the winter site fidelity of many migrants, and how important it is that their habitat remains intact during all parts of their life cycles.

There wasn't a lot of time for relaxation, but we were grateful to the FEV workers for bringing down a couple of chairs to the little spot where we had the banding area set up.

I think we banded around 60 birds in our three morning sessions. We caught fewer hummingbirds than we did in 2009, I think because the flowering phenology was different due to the very wet La Niña conditions this winter. More Guilford College students were on this trip, and everyone got a chance to learn about bird banding and participate in the process. Our thanks to John Gerwin of the North Carolina Museum of Natural Sciences, Lynn Moseley of Guilford College and her students, and Dave Davenport of EcoQuest Travel for not only allowing us to come along, but putting up with all of our niff-naw as well.

After five days, it was time to say goodbye to FEV and the Guilford group, and head to north of Jinotega for our stay at another coffee farm, El Jaguar. It will be the subject of my next post.
