[Please identify this water bird, photo attached]

Agree with Double-crested Cormorant

[Flycatcher]

Looks good for Eastern Wood-Pewee to me

[Female Black Throated Blue Warbler?]

Yes, definitely Northern Parula

[Hawk (Red Tailed ?) Mojave Desert]

I agree with Cooper’s 

[Northern AZ Gull]

Alright, thanks for the help!

[Another (last) Warbler ID.]

This is a Chestnut-sided Warbler!

[Pectoral?]

Agree with Pectoral Sandpiper

[Northern AZ Gull]

Saw these gulls in Navajo County AZ yesterday. The gulls were far out on a lake, hanging around an exposed sandbar with multiple Caspian Terns. Lots of good migrants had been pushed in by a large storm we had. I am wondering if these photos are enough to ID one or both of the gulls. I feel like they are too large (using the Caspian Tern for size reference) and dark to be Ring-billed and I currently think California Gull is a good option. Any opinions would be greatly appreciated!

[Yellowlegs or just yellow legs?]

These look like Stilt Sandpipers to me.

[Bullhead City AZ, Part 2 2020]

There appear to be multiple species in the first group, so I will do my best to identify by each image.

1. Orange-crowned Warbler

2. Warbling Vireo

3-4. Gray Flycatcher (?)

5-6. Warbling Vireo

7. Not sure

8-10. Yellow Warbler

11. This looks like a separate individual, maybe Orange-crowned Warbler (?)

12-14. Yellow Warbler

15. Mallard

[Please help confirm some ID's]

Correct! First two photos are of a Blue-gray Gnatcatcher and the last three are of a Red-eyed Vireo.

[Vesper sparrow?]

This looks like a Brewer’s Sparrow to me

[3 flycatchers in Tennessee for ID]

Agree with Eastern Wood-pewees

[AZ flycatcher]

This looks like a Gray Flycatcher to me, but wait for more opinions.

[Is this a Wilson's Warbler?]

Agree with Wilson’s Warbler

[Is it a Carolina Wren song?]

Agree with Carolina Wren

[Yellow, out of focus & far away...]

Looks good for Yellow Warbler

[Mountain sparrows]

Agree with Chipping Sparrows

[Pine Warbler?]

Agree with Bay-breasted Warbler

[Help with warblers]

Yes, your most recent image is of a Yellow Warbler. As for the sex of the Prairie Warbler, it looks to be a female or immature individual but I am not certain which.

[Duck in flight ID.]

Sorry, Tony is definitely right. I didn’t read the description and only paid attention to the birds in the front of the photo

[Swainson's Thrush?]

Yes, this is a Swainson’s Thrush. Note the Buffy eyering

[Duck in flight ID.]

Agree with Blue-winged Teal

[Immature Cooper's Hawk or Sharp-Shinned Hawk?]

Agree with Cooper’s Hawk

[Palm Warbler?]

This looks better for a Red-eyed Vireo. Note the bill, thicker than that of a Palm Warbler, the green back, the white belly, and the dark cap and eyeline, contrasting with the pale supercilium. Also note the blue legs, all vireos have blue legs
