This so much reminds me of a certain bird (and a breeding bird at that) in
southeast Pennsylvania during our 5 year breeding-bird census. In my
"block", I was well aware of a certain Blue-winged Warbler which nested in a
particular area for three consecutive years (that I was aware of). I knew
that area very well. Anyway, every time -EVERY- that I heard that male
Blue-winged calling, from early arrival until fall departure, this particular
individual sang nothing except an exact-sounding Golden-winged Warbler call
!! I would lead bird trips there and inevitably certain people were so
excited that they had heard a Golden-winged (a very rare occurence in this
particular part of the state). I knew that feeling.
This particular bird was so intriguing that certain members of the Academy of
Natural Sciences in Philadelphia wanted to "collect" the bird for further
analysis. It never happened (that's another story). Of course, it is not
uncommon that a Blue-winged will occassionally belt out the Golden-winged
song intermittently BUT not all the time throughout the year. And as far as
responding to tapes, I experimented with that very briefly during early
breeding season. When the bird first arrived on territory for the third year
(I went there every single day searching for it), I played the song of a
Golden-winged Warbler. I watched that bird before and during the playing of
the tape. When it first heard the G-w song (I played it for about 10
seconds), it looked my way, paused singing for about a minute, never moved,
then went back to singing the Golden-winged song. However, as soon as I
played that Blue-winged song for 10-12 seconds, the bird was obviously
disturbed. It flew to within 10 feet of me and loudly sang back. And what
did it sing?? The Blue-winged song for about 2-3 minutes and then it flew
off only to "revert" back to the uncharacteristic Golden-winged song (!)
Aren't birds SO intriguing???!!! This was the only time I had ever heard
this bird sing a B-w song. And for reasons all should understand, I never
attempted playing any tapes after that. Also, for the record; No, this bird
was in no physical way a hybrid (Lawrence's/Brewster's). Was it a hybrid
which maintained 100% of the physical characteristics of a Blue-winged?
Never determined.
Just thought I'd share this story with everyone.
