This is a marginal documentation shot of a female Indigo Bunting taken at High Pines on Duxbury Beach, MA Nov. 3 2012. This is an unusually late date for INBU. I saw the bird reasonably with my with binoculars and glimpsed a bluish tail, but I was unable to get a better photo than this because it was so busy in the brush I couldn't get it in focus. I saw it twice about 30 minutes apart.
The first time it was skulking with Song Sparrows, Juncos and White-throated Sparrows on the edge of the sheltered inner portion of High Pines - never more than a foot above the ground. I had decent looks via binos and tried to get a documentation shot - but this was the best I could do. You can make out the head and some blue in body feathering. I postsed a bird on 10/2 with similar bluish down feathering on the breast but its head and bill weren't right at all for INBU (I have no rersolution so far as to what it IS but consensus about what it is not!) This bird, however, has the right head as can be seen in this photo.
The second time I got a better look as it was briefly in the open on the south side of High Pines along the edge of the dirt beach road. This time I got a good look at the bird and especially at its very blue tail. Almost immediately a car drove up form the other direction and it spooked deep into the thicket preventing me from getting a photo. My general impression was that this was a bluer bird but with nothing to go on beyond that I will report a single Indigo Bunting.
