The official state bird of New York is the Eastern Bluebird. The species was named the state bird in 1970. Eastern Bluebirds are found throughout the entire state during the breeding season. They are year-round residents throughout more... the southern half of the state as well. Eastern Bluebirds are cavity nesters that will use man-made boxes when provided. This original design from Birdorable features our cute cartoon Eastern Bluebird standing before the flag of New York state.
