Southern Cali Identifications (1 Viewer)

Hi all, these IDs are tenuous for me and I was wondering if you could help.

I think these are Anna's but wanted to make sure:

This appears to be a short tailed raptor with a long bill, so buteo. Do you agree? I'm thinking RTH since no sign of banding on tail but at this time of year, a few more options. Taken at a range of probably 100m.

Is this possibly a Yellow Warbler?

Thanks much,

The hummingbird is indeed anna's hummingbird calypte anna and I believe your other two id's are on the money,rth and yellow warbler. Where in so-cal were the pictures taken?

1-2. Is a Anna's Hummingbird.
3. Is a Red-tailed Hawk.
4. Is a female Yellow Warbler.

Awesome. These were at San Joaquin Wildlife Sanctuary in Irvine. First time for a YW there for me.
