Is the bird in the attached photos a Myrtle x Audubon hybrid? A female? Something else I'm overlooking?
The bird has the yellow throat patch of an Audubon, and the yellow crown of a male, but it has no bright wing bars and is generally very pale, suggesting Myrtle. I'm puzzled by the brown in the wings, especially for a spring bird.
Although not shown in the photos, the bird had a yellow rump as well as white flashes toward the end of the tail.
Could it be a female Audubon x Myrtle still in first year plumage?
Is it just a female Audubon with faint wing bars? Do some females have yellow crowns?
Seen today at the Boulder Community Gardens in north central Boulder.
