[Ontbirds]Brewster's Warbler - Berry Tract, Hamilton

[darling]

On the mornings of May 6, 7 & 8 a "Brewster's Warbler" has been present on the Berry Tract on the south part of the loop, close to where one was observed at this time last year.  It has a Blue Warbler song and is closest to the backcross adult shown on p 428 of Sibley, except that it has some yellow on the throat.

Among the many other birds seen are Eastern Towhee in full song in clear view (one on Berry Tract and one in Cartwright Sanctuary), an Orchard Oriole on May 6, and Rose-breasted Grosbeak, first seen on May 5.
