Not a Warbling.........

Looks more like an Eastern Phoebe to me.

So I checked the Pennsylvania bird breeding atlas. Apparently Common Raven is an early nester there. So we can all agree this one is a juvenile.

I think it's just a bit early for a fully fledged juvie at your lattitude. I haven't even noticed any here in San Diego yet.

What's your location? If you are not too far north, then I agree. If not we have to consider other possibilities.

This time of year, Cassin's will give themselves away when they sing. They do the whole skylark thing, where they launch themselves into the sky, singing as they go. Botteri's just sit on top of a bush and sing.

It's an empid flycatcher, but I'm not good enough to tell you which one from these pics.

Looks good for Western Wood-Pewee to me.

Location?

Yes. Good find!

Yah, and you're in one of the very few places where Ladder-backed overlaps. I agree with Nuttall's here.

I believe I am seeing both Greater and Lesser among your pics.

You're probably right. Although I live in San Diego county, and have seen countless Brandt's and D.C., I have yet to see a Pelagic. I haven't really looked though. I need to spend a day at the coast, especially the rocky areas. I usually go to the sandy beaches with my family.

Pelagic is a possibility for the single bird, but I think the bill is too thick. Not positive though. The photo is kind of dark on my phone.
