NEW BIRD "SPECIES" FOR TOMMY THOMPSON PARK BIRD RESEARCH STATION
On Wednesday last week, a small distinctly marked warbler was extracted from a mist net and brought into the banding lab.
The extractor knew it was unusual, and upon being asked what his guess would be, he said,"Townsend's warbler"
Upon removing from the bird bag we all initially agreed with his guess!!
Upon further scrutiny, we noticed it was not quite right...the face pattern was Townsend's warbler, but the rest didn't match!!
We all decided it was a hybrid....with a Black-throated grey warbler!!
As neither of these birds occur in Eastern Canada, we took a lot of photographs, and banded and took all measurements and data we needed.
The photos were sent to the experts, and within a day we had e-mails back confirming out conclusions!!
This was a fantastic and probable first for Ontario.
We were informed that it isn't a common hybrid on the West coat where these birds occur!
We are now researching older documents to see what has been documented on this bird!
