|Song or call & method of delivery:||Series of notes all on 1 pitch: seet-seet-seet-seet-seet-seet-seet-seet in response to playback of Scott's Oriole.|
|Behavior:||We stopped the car and were doing playback for a Scott s Oriole (we had seen one a few years ago at this same spot) when we first noticed a Blackpoll Warbler about ten feet away who was reacting excitedly to the call. He was flitting around and calling in some low shrubbery about one foot off the ground and ten feet away from the car. We got good looks in good light for about 10 seconds and were able to make notes about the color patterns and call back from this Warbler. After several unsuccessful attempts at getting a picture he disappeared and did not return even though we waited and played back for several minutes.|
were they eliminated:
Black-capped Chickadee. Black cap and white cheeks with a black bib, gray back
and buff wash on sides. The Blackpoll Warbler has a black cap and white cheeks
but lacks a black bib, its back is streaky with black and dark gray and is white
underneath with black streaking on its sides.
Black-throated Gray Warbler has a strong stripey black and white face pattern with a yellow spot in front of the eye, black bib, gray upperparts, white underneath and black streaks on flanks. The Blackpoll Warbler has a black cap and white cheeks but lacks the black bib and yellow spot in front of the eye. Blackpoll's back is streaky with black and dark gray not just gray.
Black-and White Warbler has black and white stripes on the head lacking the Blackpoll s black cap and bold white cheek. Black-and White Warbler also has black spotting on the undertail coverts which the Blackpoll lacks.
this & similar species:
In 2016 I visited Magee Marsh, Lucas County, Ohio during spring migration and
submitted the following e-bird checklists for a total of 5 Blackpoll Warbler and
2 Black-and White Warblers. These warblers were seen at close range in similar
conditions to this recent sighting.
I have lots of experience in Utah with Black-capped Chickadees and Black-throated Gray Warblers since they are pretty common species.
