Note: The American Three-toed Woodpecker has one toe less than most woodpeckers, a trait that some believe allows it to lean further away from trees, delivering more forceful strikes. Threats: Forest fragmentation, insect declines/reduced food resources, fire suppression U.S./Canada Population Estimate: 1,400,000 A single granary tree can sometimes hold up to 50,000 acorns. Note: In the fall, Acorn Woodpecker groups choose a “granary” tree into which they drill holes to store acorns. Threats: Habitat loss, invasive bird species (European Starling), occasional hunting U.S./Canada Population Estimate: 2,000,000 We have omitted two vagrant species, the Great Spotted Woodpecker and Eurasian Wryneck, which rarely visit the U.S. In cases where PIF data was unavailable, we relied upon information from the North American Breeding Bird Survey. For the purposes of this U.S.-based list, we've used Partners in Flight (PIF) population and conservation data exclusive to the United States and Canada, which may not reflect global numbers. While some woodpeckers are found almost exclusively within our borders, others range far into Canada or south into Mexico and beyond. The alphabetical list below includes all species of woodpeckers that occur in the continental United States. Others, like the Lewis's and Red-cockaded Woodpeckers, have suffered large-scale declines and now benefit from intensive conservation efforts.Īmerican Bird Conservancy and other conservation organizations are helping imperiled woodpecker species by conserving critical habitat, improving land management practices, and educating landowners about the importance of forest conservation. These dangers have already proven disastrous for two of North America's largest woodpeckers - the Ivory-billed and Mexico's Imperial - which are almost certainly extinct. While a significant number of woodpecker species maintain healthy populations, none are free from human threats, which range from habitat loss to harmful pesticides. Although they vary in form and habit, most of these birds are widespread and can be found relatively easily. Hairy Woodpeckers also have a rattling or whinnying call.Excluding vagrant species, 23 woodpecker species are native to the United States (see list below).X Trustworthy Source The Cornell Lab of Ornithology Research lab of Cornell University dedicated to interpreting and conserving the Earth's biological diversity through research and education about birds Go to source It is slightly lower in pitch and does not descend at the end as the Downy's call does. Hairy Woodpeckers, however, make a similar short sharp note, described as more of a peek sound.Their call typically lasts about two seconds. The Downy Woodpecker's pik call is a rapid string of high-pitched notes that descends in pitch toward the end.However, if you listen carefully, you can detect slight differences in the calls. This is most obvious when viewing the back of the bird. White patch Downy Woodpeckers have a larger white patch on the sides of the neck.X Trustworthy Source National Audubon Society Nonprofit environmental organization focused on conservation, citizen science, and public science education Go to source On Hairy Woodpeckers this red patch is often split.
