Taken in Joshua Tree NP last week, it's still a bit early for birds and a bit cool/breezy for this time of year. The next few weeks should be better. These sparrows are reliable subjects when all else fails :)
Really nice singing pose, and I like the desert colors of the BG. Another vote for a little selective sharpening. I would trim a bit off the left side to get the bird slightly less centered.
Nice image, ditto on the sharpening - to my eye, the white balance may be a bit cool, but he stands out beautifully against the background. Congrats!

Lovely pose and BG here. Agree on sharpening the head more, and would also shift the bird to the left if you have some space on the right to use. Composition as presented here seems too centered.
