I don't know for sure what kind of bird that is, but I really like the pics you took!
Kace
Greater Yellowlegs
Those were just in auto mode.
Oh, a cold wet footed rocky belly bird.
Nice pics got pretty close awesome
You must be maxed out on your zoom or near to it,your not alone on that one Sis I do the same exact thing it's called compound error..a little movement in the camera is a big movement out there.I try to center the subject but the slightest movement pushing the button can really throw you off.Sooner or later I get it,as long as the subject is still there.
