Did you know that originally the State bird of New York was the American Robin? The Robin red breast or American robin was initially selected as the state bird of New York, but a campaign by Mrs. Charles Cyrus Marshall, President of the New York Federated Women's Clubs, in 1927 and 1928 determined that the bluebird was more popular.
It took over forty years however to adopt the bluebird as the official state bird of New York. The legislation adopting the bluebird as the official state bird was signed by Governor Nelson Rockefeller on May 18, 1970.
You can find Eastern Bluebirds in open country with patchy vegetation and large trees or nest boxes. Meadows, old fields, and golf courses are good places. Bluebirds typically sit in the open on power lines or along fences, with an alert, vertical posture. When they drop to the ground after an insect, they make a show of it, with fluttering wings and a fairly slow approach, followed by a quick return to the perch.
Insects caught on the ground are a bluebird’s main food for much of the year. Major prey include caterpillars, beetles crickets, grasshoppers, and spiders. In fall and winter, bluebirds eat large amounts of fruit including mistletoe, sumac, blueberries, black cherry, tupelo, currants, wild holly, dogwood berries, hackberries, honeysuckle, bay, pokeweed, and juniper berries.
Eastern Bluebirds put their nests in natural cavities or in nest boxes or other artificial refuges. Among available natural cavities, bluebirds typically select old woodpecker holes in dead pine or oak trees, up to 50 feet off the ground. Older bluebirds are more likely than younger ones to nest in a nest box, although individual birds often switch their preferences between nesting attempts. When given the choice in one study, bluebirds seemed to prefer snugger nest boxes (4 inches square instead of 6 inches square on the bottom) with slightly larger entrance holes (1.75 inch rather than 1.4 inch diameter). I will try next season to attract Bluebirds to my yard. Hey, you never know.
Bluebird populations fell in the early twentieth century as aggressive introduced species such as European Starlings and House Sparrows made available nest holes increasingly difficult for bluebirds to hold on to. In the 1960s and 1970s establishment of bluebird trails and other nest box campaigns alleviated much of this competition, especially after people began using nest boxes designed to keep out the larger European Starling. Eastern Bluebird numbers have been recovering since.
