Overview
Lewis's Woodpecker: Medium woodpecker with black upperparts, hood. Face is dark red, collar is gray, belly is pale red. The bill, legs and feet are black. It was named for Meriwether Lewis of the Lewis and Clark expedition. Its dark plumage sets it apart from all other North American woodpeckers.
Range and Habitat
Lewis's Woodpecker: Breeds from southern British Columbia and Alberta south to central California, northern Arizona, and northern New Mexico. Spends winters from southern British Columbia and Oregon to Colorado and south to northern Mexico. Open pine-oak woodlands, oak, or cottonwood groves in grasslands, and ponderosa pine country are preferred habitats.
Woodpeckers (Picidae)
ORDER
The taxonomic order PICIFORMES (pronounced pih-kih-FOR-meez) is divided into seven different families which include the colorful toucans, the insect-catching jacamars, puffbirds, honeyguides, barbets, and woodpeckers.
FAMILY TAXONOMY
The woodpecker family, Picidae (pronounced PIH-kih-dee) is made up of two hundred twenty-two species grouped into twenty-eight genera.
NORTH AMERICA
Fifty-seven species of woodpeckers, grouped into fourteen genera, are found in North America. The most well known of these are commonly grouped under the names woodpeckers, sapsuckers, and flickers.
KNOWN FOR
Woodpeckers are known mainly for their pecking and drumming on trees and posts, sapsuckers for their feeding on both tree sap as well as the insects they find caught in it, and flickers for being rather large and commonly hunting for ants on the ground.
PHYSICAL
The basic body of the woodpecker is comprised of a chisel-like bill used to peel bark or evacuate wood to access insects, and a stiff tail used to prop the bird as it clings to vertical surfaces such as trees or posts. Their strong feet and stiff tail allow them to form a "tripod" which is a very stable stance. Unlike other birds woodpeckers have long prehensile tongues with barbed or sticky tips which can probe ants' nests or tunnels made by boring insects.
COLORATION
Black, white, and various shades of gray and brown dominate the colors most commonly found in woodpecker plumage, with green also being seen on some species outside North America. Many woodpecker species exhibit patches of red and yellow on their heads and bellies, and these bright areas play a role in signaling. Males and females often appear similar but the males commonly have more prominent red or yellow head markings.
GEOGRAPHIC HABITAT
Most woodpeckers in North America are arboreal birds of wooded habitats but there are some species like the Gila Woodpecker that live in deserts and use cacti for nesting.
MIGRATION
A few woodpeckers seasonally leave the northern high elevations of their nesting range while others are "irruptive" species, like some hawks and owls, which will move hundreds or thousands of miles based on their food supply.
HABITS
While there are exceptions, such as the Acorn Woodpeckers who live in social communities, most woodpeckers live alone or in pairs. Most feed and live in trees, except for the flickers which have evolved a terrestrial lifestyle of feeding mainly on termites or ants, and are quite comfortable on the ground, using trees mainly as a refuge and nesting area.
CONSERVATION
Many of the Picidae family of birds are considered endangered or threatened due to habitat loss. The Ivory-billed Woodpecker and the Imperial Woodpecker have been considered extinct for 30 years. However there is some recent controversy recently whether these species still exist, particularly the Ivory-billed Woodpecker, which some researchers believe has been filmed in the swamps of Alabama.
INTERESTING FACTS
Rather than sing songs like many birds, woodpeckers tap their bills rapidly against trees, logs, or posts (and sometimes even house siding or drainpipes, much too many home-owners' annoyance) to attract mates and proclaim territory. In fact the length and speed of the drumming, as well as its intensity can be used to identify different species.
