I find bird to be very frustrating creatures. They will wait, perfectly poised, while you get your camera ready. However, they have some uncanny sense that tells them when you are finally ready and at that moment move or fly away. This bird was quite intent on what it was doing though and I was able to get a decent shot.
These little birds were everywhere cleaning up after everyone (animals and humans…mostly humans). If you know what kind of bird it is, please let me know.
