Family Guy, S07E02 'I Dream of Jesus': Peter: Brian, can I see that paper for a sec? (Brian gives Peter the paper. Peter peruses the paper.) Peter: Huh... that's odd... I thought that would big news.

Hmmm... Looks a lot like an eastern Phoebe, which loves to hang out on power lines. But the bill seems a bit on the small side. But none of the other flycatchers seem to fit.

I'm going to call that a rough-winged swallow, based on the "buffy throat", "no contrasting markings", and the lack of long wingtip projection (quotes from Sibley). I'd prefer to see less of a notch on the tail, but I'll chalk that up to how the bird happens to be holding its tail feathers.

A swallow, not a flycatcher. Probably a rough winged swallow.

But. I'm not happy about the shadow on the throat and the dark spot on the chest. Still, I think a bank swallow at that time of year would have a much more distinctive breast band.

A Bank Swallow would indeed have a distinct band breast band.

Cave Swallows normally have dark-centered vent feathers (undertail coverts). This bird has pure white vent feathers.
