Subject: [Tweeters] Changes in bird populations in Washington over that last
Date: Apr 3 11:38:22 2006
From: Matt Bartels - mattxyz at earthlink.net


Here are a few more candidates, with info drawn from the Wahl et.al.
Birds of WA book.

White-faced Ibis - only 3 records before 1981
Least Flycatcher - first record 1958
Swamp Sparrow - first record 1973.
White-throated Sparrow - only 6 records in WA [Jewett] before 1953

And on top of those, does Wild Turkey count? Introduced, but rapidly
expanding range?
Not sure what to do with Cattle Egret too - Coming, but not quite
here in force yet...
