That's a young Red-shouldered Hawk. Note the slim shape, pale barring on the secondaries, red shoulders, heavy streaking on the undersides, and narrow bands on the tail.

I would agree with a Common Snipe, due to the very buffy breast/upper flanks, broad buffy lines across the back, and plenty of rufous internal markings on the tertials.

Yes, that’s an adult Lesser Redpoll. It is by far the most abundant redpoll sp. in the UK. To differentiate from the Common (Mealy), note the brownish wash, very streaky overall, and less contrast on the upperparts. Hoaries are much more white and don’t have streaking on the undertail coverts. However, I believe that all of the redpoll species should be lumped together. It’s a wonder why they didn’t do that already...

Yes, this is an adult Cooper’s Hawk. Note the very bulky overall, relatively large, blocky head, and eyes close to the front of the head. Like you were saying, the uneven tail feathers from underneath (the outer tail feathers are shorter than the outer) are a telltale sign of a Coop. The lighting is probably making it hard to see the light nape.

This is an adult Cooper's Hawk. Note the very bulky overall, relatively large, blocky head with a light nape creating a capped appearance (Sharp-shinned would have a dark nape on a rounded head creating a hooded appearance), eyes close to the front of the head, and thick legs.

Sedge Wrens would have a much paler overall with more streaking on the upperparts yet less barring on the flanks. Overall, Sedges can camouflage better in pale grass while Winters can blend into thick tangles. I think that's a good way to remember the two.

I agree with a Winter Wren. Note the shorter bill, shorter tail, more barring on the flanks, and darker, plumper overall than House Wrens.

Yes, this is a Pacific-slope Flycatcher. The teardrop-shaped eyering is a key field mark as well as the yellow-olive color (especially on the throat). The very similar Cordilleran Flycatcher can safely be ruled out be range (Cordillerans live farther east).

This is actually a Chipping Sparrow. Field Sparrows would have a rusty (not blackish) eyeline and Swamp Sparrows would have more extensive rust-color on the wings. Both Field and Swamps Sparrows lack the distinctive dark lores of a Chipping Sparrow.

Well, you're correct this time! It is indeed a Ruby-crowned Kinglet. All vireo species in North America would have blue (not orange) feet, lack the horizontal black bar behind the wingbar, and have noticeably thicker hooked bills.

That’s a Yellow-rumped Warbler (Myrtle subspecies). Note the streaked sides and pale throat that wraps around the back of the auriculars.

Interesting bird. Here are my (inexperienced) thoughts: I think that this is might be a valid taverneri individual. In terms of head/bill shape, it is quite spot on, which the rounded crown and sloping forehead that blends right into a relatively thick, blunt bill. In terms of size, this subspecies is supposed to be pretty large. I can't assess from this photo, but maybe you could from your experience with this bird. The breast coloration looks fine, but the underparts are quite pale (taverneri should show darker bellies than breasts). There is no breast band and the upperwing coverts are hard to assess from this photo. To sum up, I would probably guess taverneri but definitely wait for more opinions. Maybe @akiley can give his opinion.

Lincoln's Sparrow confirmed. Note the neat appearance with the crisp streaks and buffy wash across breast.

1. Yes, immature Golden-crowned Sparrow. Note the large size, broad rusty stripes on the cap, and yellow on the front of the head. 2. Yes, Yellow-rumped Warbler. Note the yellow patches on the sides.

That’s quite interesting. You’re in the extremely narrow range overlap of the two titmice, which cuts right through the middle of Texas. It’s apparently common to see these hybrids at your location — I used to think they were seldom seen. If you see the eBird map, you can see how thin this range overlap really is: https://ebird.org/map/bcxtit1

Yes, with the rounded head shape and broad bill and nail, all the scaups are a male and female Greater and there is indeed a male Lesser on the right in the second photo. Edit: Sniped by Alex!

That’s a female House Sparrow, due to the plain buffy overall, pale contrasting eyebrow, and stout bill. In case you were wondering, Hawaii is just another place in which this invasive species has been introduced.

This is a late Barn Swallow (rufous on the face and black-and-white striped tail). Very nice find.

That's a Savannah Sparrow. Note the small pink bill, short tail, tan cheeks, crisply streaked underparts, and yellowish stripe above the eye.

This is a Sharp-shinned Hawk. Based on the shape of the hawk, you can observe that it is an accipter, not a falcon, due to the long tail, broad wings, and broad chest. Based on the plumage, note the thick black-and-white bands throughout the tail that American Kestrels lack.

Red-throated Loon is correct, due to the slender, upturned bill.

Yes, this is a White-winged Scoter. Just based on the silhouette, the head seems blocky, very much like a typical Surf. But this bird is in a erect position, which is probably forming its head into this shape. Note how this bird still has a sloping forehead, which is typical of WWSC. Based on the photos alone, one can make out a mostly feathered bill, WWSC-shaped bill, unraised tail, and white conspicuous wingpatch that is absent in Surf/Black. Also, note how this bird is noticeably bulkier than the Surf in front of it.

These are Pine Siskins. Note heavily streaked, brown overall, the small amount of yellow on the wings and the tail, and the sharp, pointed bill. Red-winged Blackbirds are noticeably larger and lack the yellow on the wings.

1st winter Franklin's Gull confirmed, due to the limited black on the underwings, clean dark half-hood, and dark tail band that does not reach the outermost feathers. Nice bird.

I agree with young Eurasian Blackbirds. The left bird is a immature male almost completely molted into adult plumage, and the right is a much younger juvenile. I don't believe the right bird is sexable at this point.
