American Three-toed Woodpecker - Picoides dorsalisThe Three-toed Woodpecker is a small woodpecker of western North America, much of Canada, and down into New England. They can often be overlooked, as they're not a particularly vocal species, and often will forage by working over one individual tree for quite some time. They are strongly associated with spruce forests, and are very found of the larvae of spruce bark beetle. Until 2005, the species was considered to be the same as the Eurasian three-toed Woodpecker (now Picoides tridactylus).

In South Dakota, they are found exclusively in the Black Hills, where they are permanent residents. They are most often found in higher-elevation areas of the Black Hills that have older spruce tree forests, or in and around recently burned areas with extensive standing dead timber.

Habitat:

Found in conifer forests of the West, most often being associated with spruce.  They are also very often found in areas with dead standing trees, such as those killed by fire or flood, as wood-boring insect infestations tend to favor these areas.

Diet:

Primarily feeds on the larvae of wood-boring beetles. Also eats other insects, fruit, berries, and will occasionally consume sap from sapsucker bore wells.

Behavior:

American Three-toed Woodpeckers typically forages on conifer trees, moving deliberately and scaling off the bark to gain access to insects underneath.  They are usually solitary outside of the breeding season, although densities of birds in favorable areas such as recently burned forests may bring several birds into the same general vicinity.

Nesting:

June and July. American Three-toed Woodpeckers nest in tree cavities, usually constructed in a dead conifer tree, but they will also sometimes create a cavity in a live tree. They have often been known to construct cavities in wooden power-line poles. Both the male and female American Three-toed Woodpecker share responsibilities during the breeding season, as both help to construct the nest and incubate the young. The female lays between 3 and 6 eggs, with the incubation period lasting about 2 weeks.

Song / Vocalizations:

American Three-toed Woodpeckers aren't a particularly vocal species.  The most commonly heard vocalization is a sharp pic call.  They also have a rattling call, and drumming that usually often rapid in pace and slows towards the end.

Migration:

Most are permanent residents, although those in northern Canada may move southward a short distance in winter and others may move from higher to lower elevations.Most are permanent residents, although those in northern Canada may move southward a short distance in winter and others may move from higher to lower elevations.

South Dakota "Hotspot":

American Three-toed Woodpeckers are only found in the Black Hills of South Dakota. They can be found in and around two specific types of habitats in the Black Hills...recently burned areas with dead standing timber, and higher-elevation areas with spruce trees. Examples of higher-elevation areas where they might be found include the Sylvan Lake area and up towards Black Elk Peak, or further north in the hills, in the higher elevation spruce areas near Hanna Campground.

Conservation Status: Systematic surveys show generally stable numbers overall, in both its Eurasian and North American ranges. Although they can fluctuate with availability of suitable habitat, they are found across a very broad geographic area and are relatively common in parts of that range.  The IUCN considers the Three-toed Woodpecker to be a species of "Least Concern".
