![]() The downy has a short, stubby beak that is just slightly longer than the space between the front of its head and the corner of its eye. Downy woodpeckers are more common than hairy woodpeckers.Įxamining the structure of their bills is a more reliable technique of determining the size disparities between them. Hairy Woodpecker Differences between Downy Woodpecker vs Hairy Woodpecker Appearanceĭowny woodpeckers have several black lines or spots on their whitish tail feathers, but the outer tail feathers of hairy woodpeckers are normally plain and unmarked. Many are permanent residents however northernmost populations may migrate south in winter. The average lifespan is four years (wild) Feeds on wood-boring beetle larvae, ladybugs, wasps, moths, and other insects. They like suet feeders and enjoy millet, almonds, and chunky nuts.Įat mostly bugs. Some time make a flock of 2-3 birds but prefer to live alone In much of the Eastern U.S., Hairy Woodpecker has totally white outer tail feathers. These black bars are best seen from below. The Downy Woodpecker’s whitish outer tail plumes are commonly speckled with black. The Hairy Woodpecker may be found from the coast to the highlands in North America and Central America’s mountain forests. In comparison to the Downy Woodpecker’s call, the Hairy Woodpecker’s sound is petite, sharper, and more powerful.ĭowny woodpeckers are indigenous to deciduous forests in North America. Downy Woodpecker Overview Downy Woodpeckerĭowny Woodpecker makes the whinnying call which lasts for about 2 sec. View the overview below to see how the Downy Woodpecker and the Hairy Woodpecker differ from one another. Interesting facts about Hairy Woodpeckers.Interesting facts about Downy Woodpeckers.Similarities between Downy Woodpecker vs Hairy Woodpecker. ![]() Differences between Downy Woodpecker vs Hairy Woodpecker.Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create. Again, this may be the result of convergent evolution and the complex spread of woodpecker genes from its earliest ancestors. Many woodpeckers look very similar to both downy and hairy woodpeckers, not only in the Americas but on other continents as well. Other theories suggest that downy woodpeckers grow similar feathers to furry woodpeckers to trick them and other species into helping them become more dominant. The same advantage one species has in developing its traits and markings may benefit other species. ![]() The similarities between Downy and Hairy woodpeckers are the result of convergent evolution. ![]() This is not uncommon in birds – crows and rushes are examples of birds that are not all that related even though some species look nearly identical to each other. ![]() Juvenile long-haired woodpecker Why are Downy and Hairy woodpeckers so similar?ĭowny and Hairy woodpeckers are very similar, although they don’t even belong to the same genus (Downys belong to xerophytes belongs to, and Maomao belongs to Pearl genus). ![]()
