Banding recovery: Michigan robin in Mississippi

Hot on the heels of a report of an RRBO-banded robin found in Louisiana last month, is another southern recovery. This robin, first banded here on campus as a hatching-year bird on 30 September 2007, and was found dead 5 miles north of McLain, Mississippi on 8 March 2010.

Interestingly, we recaptured this bird on 11 October 2008, when we determined it was a female. The bird was molting wing feathers when it was recaptured, which birds typically do on the breeding grounds rather than during migration. Recaptures of passage migrants are quite rare, as well, so this was likely a bird that nested somewhere on campus or nearby.

This is the 9th robin banded on campus recovered outside of Michigan. Most of them (6) were originally banded in fall (the others in spring and summer), and recovered en route to, on, or en route back from their wintering areas. This map shows all 9 areas where the robins were recovered. The Ohio bird was found just a month after it was banded in fall, so it was likely still southbound. You can click on the markers for details.



This is certainly demonstrating a pattern of Michigan robins -- breeding or migrant birds -- wintering in the southeastern U.S.

A similar map and chart of all of our out-of-state banding recoveries is on the RRBO web site.

Florida seems like a better place for Robins... I'm just sayin'...
