There are a very large number of birds that live in or travel through Connecticut. At least 400. I will not be able to cover them all! Over time I will try to cover some of the more common ones, ones I see often, particularly interesting ones and so forth. But I know I will never get them all.
You can find more complete name lists of what birds are seen in Connecticut in the links section. Look for the ARCC and the Connecticut Ornithological Society links.
