I came across this very outgoing bird on a walk around Walden Pond in Concord, MA. I almost didn't take the picture because I was sure that as soon as I aimed the camera it would fly away. However, it must have been pretty used to walkers; I was able to take the first photo and still had time for more before it flew away.
If anyone out there knows the name of the bird, I would be very appreciative of a comment about it. I'm fairly sure it's a young bird, since its colors aren't very developed. Its colors look fairly uniform except for a possible reddish brown mark on the inside part of the tail.
