Is this an empidonax flycatcher? I observed it flying out to catch insects and returning to a different perch each time. Thank you in advance.

Please help me ID the birds that are standing on one leg in the photos. I thought they were willets at first but the bill appears too short. This was at Bolsa Chica Ecoological Reserve in Huntington Beach, California. There's a marbled godwit for size comparison in the first photo as well as a couple smaller birds that I believe are dowitchers. These same dowitchers are on the right side in the second photo.

Saw this small grayish bird this morning and couldn't get a very good picture of it. This was taken in Los Angeles, California.

Both birds were seen in the morning at a soccer field near Las Vegas, Nevada. I took some very poor quality images through my binoculars. 1. The first bird was small and brown had a prominent black bib as well as some black face markings that I could not get a good view of. From review of the poor quality photos afterwards it seems to match the black bib and face marks of a Horned lark. Can this be confirmed with such poor quality photos? 2. The second bird was seen a hundred feet away from the first bird and was with a similar looking partner. It was also small but slightly lighter brown than the first bird and without any black markings. From the photo I managed to take through my binoculars the most notable feature was that its back feathers had more contrast with lighter and darker areas giving it a more "spotted?" appearance. . .
