Bachman's Sparrow in Dearborn, 1946

NOTE: In anticipation of publishing a new Dearborn bird checklist, I am posting information on some of the city's more interesting sightings. 


Alice Miller was a Dearborn bird bander and active contributor and compiler of bird surveys in the Detroit region into the early 1950s. She wrote several short papers on unusual bird sightings, and regularly submitted records to the Detroit Audubon Society which were subsequently published in Michigan Audubon's Jack-Pine Warbler for their regular seasonal bird surveys.  Her home was in west Dearborn near Ford Road and the Dearborn Country Club (established by Henry Ford in 1925). At the time, the neighborhood was not fully developed and had quite a bit of open land. 

On 8 May 1946, Alice Miller discovered a Bachman's Sparrow (Peucaea aestivalis) across the street from her home. It was a singing male, and present until 13 May when it was procured as a specimen by Ralph O'Reilly. This specimen is now in the University of Michigan Museum of Zoology (a photo can be seen here).

This was the second record of this southeastern sparrow for Michigan, the first being one taken as a specimen in Erie Township, Monroe County on 29 April 1944. According to The Birds of Michigan and other sources, there were only a few additional sightings: one in Ann Arbor (Washtenaw Co.) 23-24 April 1948; one in Livingston Co. on 27 July 1954; and one in Macomb Co. on 26 April 1964.

Miller wrote a full account of this sighting, with some background on vagrancy in this species, in the Jack-Pine Warbler; following that article is a short note by O'Reilly on both individuals. You can read the PDF here.

European Goldfinches and other cage birds in the Western Great Lakes

I have posted an updated page on European Goldfinches and other non-native cage birds in the western Great Lakes. I am still collecting follow-up data while the Wisconsin Breeding Bird Atlas is in its final year of surveys; southeast Wisconsin and northeast Illinois are the "epicenters" of the breeding population of European Goldfinches. I'm working on a summary paper -- read all about the history, identification, and how to submit reports here.
