Meade suggested two possible causes for this species’ expansion: “In the 1960s residential bird feeding began to be more popular, giving the Red-bellied Woodpecker an increased food supply; second, it was during the 1950s and 1960s that elms were dying from Dutch elm disease, particularly in river swamps. These dying trees (upstate) attracted wood borers and other insects, providing additional food and nesting sites. The resulting growth in population provided pressure for range expansion.” (Andrle, p. 228) Reforestation of abandoned farmland in New York has probably helped this species as well. Also working in this bird’s favor is the fact that it adapts to a wide range of wooded habitat, even urban areas; feeds opportunistically on a wide range of insects, mast, fruits, seeds and sap; and uses a variety of foraging techniques as needed. (BNA 500: 1, 4-6)As these birds became more common in our area, more of these varied feeding techniques became evident. “This year, for the first time, reports have come in of Red-Bellied woodpeckers visiting feeders and dining on sunflower seeds,” John Brown reported in 1959. (BA, 3 December 1959) “At first this was a little hard to believe, but we now have one that is a steady sunflower seed customer. He backs down the tree trunk to the feeding shelf, grabs a seed, takes it away, jams it in a crevice and extracts the meat the same way the nuthatches do.” A female at the Gillette farm in Savannah “uses a small hole in an adjacent tree as a sort of tool. When she takes sunflower seeds, she quite often drops them in the hole, where she shells them without worrying about dropping the tasty meat on the ground or into the snow.” (Birds, 12 March 1989)Pat Martin, scouting Durand-Eastman Park in advance of a 1 January 1992 field trip, enjoyed watching one “hanging upside down ‘bobbing’ for a crab apple. It dislodged the apple from the tree, flew off with it in its beak and landed on a horizontal limb where it proceeded to peck at the apple from above (to get at the worm inside?). Pretty neat.” (LG, January 1992) Nonetheless, like other cavity dwellers, it must compete against Starlings. The tenacity of this woodpecker – and the challenges its faces – were amply illustrated on 22 May 1996 in Badgerow Park. A Starling was perched near a Red-bellied Woodpecker’s nesting cavity, apparently intent on usurping it. The Red-bellied flew at the Starling, “tangled with it,” this birder recorded, “but the Starling was more than able to hold its own. This went on repeatedly, with the Red-bellied giving alarm calls constantly and periodically retreating to its cavity, going in, immediately coming out and diving at the Starling.“At one point the Starling actually slipped around the Red-bellied and went into the cavity; the Red-bellied followed it right in. After a second or two out comes the Starling followed by the Red-bellied, and that seems to end the encounter – at least for the time
