[Tweeters] Fw: Re: Robins and thrush

[Robert O'Brien via Tweeters]

There's more
I heard from Dave Swayne off line, who can't reply through Tweeters,
because he's in digest mode.
He sent me the page for Varied Thrush from the Wonderful Washington
Breeding Bird Survey of a few decades ago.
I won't try to reproduce that page because I can't attach it, but will just
relay the BBS conclusion for VATH.   Formerly bred in the Seattle Area but
does not any more.  Lots of data for the obsessed if you access the WA BBS
online.  And, if you're not obsessed you would not even be reading this.
Of course that does not mean that NO Varied Thrushes nest in the Seattle
any more.  Just that the BBS did  not find any decades ago when the BBS was
run.
