Need help with three birds please

[Turtlebird]

I got these birds at Point Pelee yesterday...

1.


2.


Finally, another gull that I just thought looked a bit different than the rest.  It's a juvenile, but the tip of it's bill is all black unlike ring-bills and it's wings seemed to have more black.  It could be a juvenile herring gull but I thought they had all-black bills?

3.


Any help would be much appreciated!!

1. If it was flicking its tail, it is an Eastern Phoebe
2. Brown-headed Cowbird (juveile)
3. Ring-billed Gull: 1st winter plumage (see National Geographic Field Guide)
Rayfield Pye

Indigo Bunting.

I agree with female Indigo Bunting for #2.  The beak isn't heavy enough for cowbird.
