Buffleheads are perhaps the most uncommon wintering duck in the Phoenix area that is still widely expected throughout Maricopa Country, meaning they're not rare, but they're readily visible either. They're small birds themselves of course, and they're numbers are small compared to all of the other larger ducks species. They tend to prefer larger, deeper bodies of water, which makes them more unusual to spot and photograph without a scope. Like lots of other diving duck species, they're also more skittish, and make photo-documentation tricky.
While looking for Mergansers out at Fountain Hills Lake, I could see the white and iridescent fontanel of a male Bufflehead out in the center of the water. He had a female friend with him, and while he always stayed situated pretty centrally in the big body of water and out of range, she'd periodically fly around in a state of considerable distress, as if she's just woken up and realized she was in the middle of a desert or something. Anyway, this is a photo-first for Butler's Birds.
