The report of a Brewster's Warbler at Weston Bend Saturday interests me --
particularly the fact that it was a backcross. Some will remember that I
found a 1st generation Brewster's at Weston Bend May 5, 2000 near the gas
line crossing considerably south of the toilets. The bird came in to a tape
of a Blue-winged Warbler song.  I refound the same bird by the same means at
the same location May 9, 2001, but when I played the tape on May 4, 2002, at
that location, a male Blue-winged Warbler came in. I am speculating that
this 2003 backcross found at a different location is a descendant of the
2000-2001  bird and a female Blue-winged Warbler with which it mated.

I am not sure whether the 2002 bird was a first generation bird or a
(white-breasted) backcross. If anyone knows, I would be interested to learn
that.
