Jean, that's what I thought at first, too. In fact, that's what I labeled the picture in my files. But the blue is different. We had an indigo bunting last year and the blue was so iridescent, jewel-toned. This is didn't look like that one. I wondered if this one was a type of bluebird other than the usual Eastern bluebird we so often see (which does not come to the birdfeeder). GL
GrannyLois, just checked Petersons Field Guide for Eastern Birds...there is the Mountain Bluebird (turquiose-blue, paler below, belly whitish). It's range is Alaska, W. Canada to the SW US..rarely seen in the East. Could be the Blue Grosbeak. I could not tell by your pic, but did your bird have tan bands on the wings?
Jean and Calalily, it has darker blue bands on the wings. I just checked my bird book (National Audubon Society Field Guide to North American Birds), and it looks just like their picture of the indigo bunting. It doesn't have the tan bands of the blue grosbeak. The shade of blue just threw me off - I guess it changes according to how much sun is on it. Thanx for helping. GL
