What a sweet image, somewhat hard to find the bird, but once found...wow...just saw the other two! Groovy scene, busy, but so are sparrows, so it suits them well.
Toning and depth of field for this are perfect. First I see one little guy - cute puffed up little thing. Then another. Then another, and finally I realize there are at least four of them, yet each seems to be in its own little world. A very pleasing photograph to visit.
