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!

Dearborn portion of the Detroit River CBC, 2012

The Detroit River Michigan-Ontario Christmas Bird Count was held, as it is each year, on January 1. This was the 35th year for the count, which is centered at I-94 and Warren Ave, and the 18th year that RRBO has coordinated the field work in the city of Dearborn.

The day began with mild temperatures which had been the hallmark of the autumn and winter season up to that point. All water was open, and there was (and had been for the most part) no snow cover. Waterfowl and seed-eating birds were dispersed far and wide. We'd seen an excellent fruit crop in late summer and fall, but most had been stripped by the time New Year's Day arrived.

We ended the day with 39 species, well below the average of 46 because the party covering the Ford Rouge Plant was denied access this year (not by Ford, but by the private security firm of another company). Thus, we missed a number of species of waterfowl and the two dozen or so Black-crowned Night-herons that typically roost in a small pond on the property.

Nonetheless, the day was not without highlights. Covering the UM-Dearborn campus, Greg Norwood found one of the Gray Catbirds first found on 20 December. This is a new species for the Dearborn portion of the count and brings the cumulative total to 87. A Sharp-shinned Hawk seen on 29 December couldn't be located, but is tallied as a "count week" species and is also new for the count. Greg also found the Yellow-bellied Sapsucker that has been hanging around for weeks. This is only the second time sapsucker has been found on the Dearborn portion of the count.

Darrin O'Brien and I covered the various plantings on Ford properties. Like last year, most of the seed-eating birds were found at the fields in front of Ford World Headquarters. Most numerous were House Finches (over 900) and House Sparrows (over 1800). The day's total of 1038 House Finches was a new high for the count. Many of the fields had a lot of standing water, making it harder for the little birds that like to forage on the ground. The total of 26 American Tree Sparrows was a new count low. Also present at Ford HQ was a Peregrine Falcon. It chased around a Red-tailed Hawk before landing on the Ford building.

Arrow points to grooming Peregrine.

Cathy Carroll turned up 18 Great Blue Herons along the concrete channel of the Rouge. Often this group of birds roosts along the river on campus, but forages all along the river. She also saw one of the seven American Kestrels in the city, which is a new high for the count.

Finally, only one American Crow was found all day. This is a new low, and represents a decade of counts with fewer than 20 crows (most years fewer than ten). The local population has simply not recovered from West Nile virus, and I am beginning to wonder if I will ever see new birds move in.

Keep those silver bracelets coming....

This Cooper's Hawk is just one of over 33,000 birds of 122 species banded by the Rouge River Bird Observatory on the campus of the University of Michigan-Dearborn since 1992. Our banding program is supported by donors like you. Help us continue this long-term conservation research project by making a contribution today.

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!

Fall 2011 banding wrap-up

Our official fall banding season ended on 8 November. I had really hoped to squeeze in a few more days, but the wind or rain prevented me from doing so. I have posted a full summary with photos and stats on the RRBO web site.

Because we had a number of nets that were damaged by deer, instead of trashing them I moved them all into one area and decided to leave them up a little longer. As we have some warm days in November and December, I hope to catch a few more robins (and maybe even a wintering Hermit Thrush) to see what fruit they continue to eat as winter sets in.

As we identify and compile our seed samples from this fall and add them to our database, expect to see a blog post or two on what we have found our birds to be eating. Plus, a couple of exciting projects are being to come together, and of course our winter bird survey is also fast approaching. Stay tuned.
