As promised, more shots from my yard work photo project! These little guys fly in a large, loose flock of small songbirds-sparrows mostly. The males, I think, have a larger head than the females. I think #1 and #5 are images of male White-crowned Sparrows.
D500, 500pF, 1/1000, f 6.3, ISO from 1100 to 5000, no EC or filters. Handheld.
Downs have the details!
