...Actually, this is a tale of two throats...when I posted the photo of the yellow-rumped warbler the other day, I decided not to mention that (according to my birdie field guide) there are two types of this bird, but because they inter-breed and create hybrids...who knows which you're really looking at...and I figured I'd never see both variations...ha! Surprise!
The Eastern "Myrtle warbler" (male) has a white throat like the one below, and two white wing bars...this one seen near Roughlock Falls in Spearfish Canyon...
I took a drive to Sylvan Lake and Needles Hwy. yesterday, and at the lake who did I stalk along the shoreline, but a Western "Audubon's warbler", with a yellow throat!
He was surprisingly tolerant of my shadowing him.
