Fall Bird Migration

 

(This 803rd Buffalo Sunday News column was first published on August 20, 2006.)

 

Among my most popular columns were those that listed approximate dates for spring bird migration. In response to a number of requests I offer now a similar listing for fall. These dates are based largely on the Buffalo Ornithological Society's "Seasonal Checklist of the Birds: The Niagara Frontier Region", a 2002 compilation by a committee headed by David Suggs.

 

As should be clear from the following listing, the fall migration is already well underway. I have always been amazed at how soon after nesting shorebirds, cuckoos, flycatchers and even tiny yellow warblers leave. Birds of the year have only been fledged for a few weeks when inbred instincts compel them and their parents to leave on flights of a thousand miles and more to the south.

None of these dates is set in stone. As the weather has moderated over the past half century, arrival and departure dates are being extended and more and more birds, like robins and bluebirds, overwinter.-- Gerry Rising
