Melanerpes carolinus
Common eastern woodpecker, despite the name almost entirely zebra-striped on the back with a bright red cap (the belly blush is faint). Calls loudly and frequently, a familiar voice of eastern hardwood forests.
Widespread and abundant; no known immediate threats to the population.
The 'red belly' is faint, usually just a pink wash low on the belly, while the most visible red is on the head, leading many birders to misidentify it as Red-headed Woodpecker.
One of North America's most widespread woodpeckers, has expanded its range significantly northward over the past century, now common in southern Ontario and Massachusetts where it was unknown 100 years ago.
Caches food year-round, wedging acorns and seeds into bark crevices and cavities for later retrieval.
Pairs mate for life and stay together on territory throughout the year, both partners contributing to cavity excavation.
Resident across the eastern US and southern Canada, with the range expanding northward decade by decade.
Abundant year-round from Texas east to Florida and north to New England.
Common breeder, expanding north into southern Ontario and Michigan's Upper Peninsula.
Body sized to 6"×6" floor. The 2½" panel locks out larger nest competitors while letting the Red-bellied Woodpecker pass cleanly.
Aggressive cavity excavator, may evict bluebirds and chickadees from boxes.
