The last Dearborn Barn Owl

Barn Owls (Tyto alba) are considered extirpated as breeding birds in Michigan. Although I suspect that occasionally a few persist, for the most part the lack of open, fallow land has decimated their numbers across the Midwest, a fate shared by many other grassland species. The fact that Barn Owls were probably very rare prior to Michigan's logging heydays when the state was mostly forested is little consolation for their lack of residency today.

The last (maybe the only) observation of a Barn Owl in Dearborn occurred on 6 May 1951 by Robert E. Mara, a frequent contributor to the Bird Survey of the Detroit Region into the mid-1950s. These surveys provided the basis for Alice Kelley's book Birds of Southeastern Michigan and Southwestern Ontario as well as material for my own books on Dearborn birds. On the original field sheets for the survey, I found Mara's notes:

The image below is from 1949. Mara resided at the Dearborn Inn (1 on the image below), across Oakwood Boulvard from what was (up to 1947) the Ford airport (2) and is now the Ford proving grounds. Many of his surveys were walks he took every Sunday up Rotunda Avenue to the Rouge River. The location of his sighting at Oakwood and Southfield is marked 3 on the map. It's incredible to see the difference 70 years makes!

The border between Dearborn and Allen Park is the Southfield Freeway (M39), a much sleepier road in 1951. Mara's sighting of the Barn Owl "in the woods near the intersection" could place it west of Southfield in Allen Park, although he designated his sightings for that day in Dearborn. At the time, Allen Park was not a city but a village of Ecorse Township, and customarily observers designated "Ecorse Twp" on survey forms if that was their location.

Any doubt that Barn Owls occurred in Dearborn was eliminated in 1991 when Jim Fowler, Jr. found a very old Barn Owl skull in a chimney near the clock tower at the Henry Ford Museum; the museum was well-established by the time of Mara's sighting. It was rumored that Barn Owls once nested there, and Jim found the evidence that they were at least present in the area some years in the past.

Postscript: There was a report of a "possible" Barn Owl seen in flight over west Dearborn on 27 June 2008.

The updated Dearborn bird checklist

I've now put up a revised version of the Dearborn bird checklist incorporating changes through 2018. A link is also in the sidebar.

This checklist complies with all taxonomic changes made by the American Ornithologists’ Union to the 7th edition of the AOU Check-list of North and Middle American Birds, through the 59th Supplement, published in 2018.

The Dearborn bird checklist contains 263 species plus two hypothetical species, most of which were recorded on the University of Michigan-Dearborn (UMD) campus and adjacent green space. Records were compiled from over 50,000 banding records from programs that took place on the UMD campus (from 1971-1987, and 1992-2014 as the Rouge River Bird Observatory) and elsewhere in the city; thousands of standardized surveys, mostly by RRBO; published historical records, archived photographs, and documentation; and other material determined to be credible. Links to supporting information on some of the more interesting species are included in the checklist below.

If you are interested in the residency status, relative abundance, dates of occurance, and sighting locations of these species, detailed information, plus a guide to birding in Dearborn, references, article reprints, and data tables is in the book The Birds of Dearborn, An Annotated Checklist, published in 2007. A PDF is available for only $7.

I am currently considering work on a complete update of the annotated checklist portion of this book. It would include details on over a dozen new species recorded since 2007, hundreds of new dates on arrivals, departures, etc., and dozens of status changes.

If there is sufficient interest from people that would like to purchase a copy of an updated annotated checklist I can determine how much it will cost me to produce a final self-published PDF. It would likely be around $5-8. It would not include all the maps, detailed location information, and appendices of the currently published book. If you think you are interested, leave a comment on the form in the sidebar (just as feedback, no commitment!) or on the Facebook page so I can determine what to do. Please let me know your thoughts!
