They have been known to destroy crops of cherries and small fruit. (Bent 1964)
Lewis's Woodpecker eats mostly acorns and wild berries of varying varieties. They enjoy grasshoppers. They have been known to eat them exclusively until the grasshoppers were gone. They also eat many other insects. A set of these birds were watched for about forty-five minutes darting from their perches to catch insects and never missed catching one and in that time they ate thirty-five insects. Because they eat insects, they are beneficial to farmers. They prefer dead trees, so they don't harm living ones. (Bent 1964)
The Lewis's Woodpecker is known to have a hoarding instinct. About one-third of its diet consists of acorns, which it stores in cracks and bark furrows. In addition to acorns, the Lewis's Woodpecker eats insects of different kinds, including ants, crickets, grasshoppers, etc. This bird has been seen catching may flies and hoarding them by putting them in crevices of pine trees, mostly in the trees where they nested. It has been noted that they are excellent flycatchers and have extremely fine vision, catching insects which were about 100 feet from where the bird was perched. It also eats wild berries of varying varieties, in addition to pine nuts, juniper berries, cherries, and apricots. (Bent 1964, Eckstrom 1901)
Melanerpes lewis is found in California, north to western Washington to northwestern Montana and the mountains of Colorado. They have been seen as far south as the southern Counties of California, although they are uncommon there. They are most common in the southeastern San Joaquin County,Ca., north to Southern Oregon, and along the coastal ranges from northern Tehoma County to Southern San Luis Oispo County, Ca. There have also been sightings in Utah, British Columbia, Texas, and Mexico.(Bent 1964, Winkler et al.1995)
Biogeographic Regions: nearctic (Native )
Lewis's Woodpeckers prefer logged or burned out areas. They prefer old growth woodlands rather than dense forest. In Montana they nest in the transition zone between 2,000 and 3,100 feet elevation. In winter they choose oak woodland or commerical orchards such as almond and walnut and pecan trees. (Bent 1964, Winkler et al. 1995)
Terrestrial Biomes: forest
Adult Lewis's Woodpeckers have a medium sized head, short neck, and large body. The bill and feet are dusky blue-gray. The back of this species is black, glossed with green, and the belly is rose red. There is a deep red band which runs across the forehead and throat, extending behind and below the eye. The throat and wings are black with a band of dull white over the hind neck extending forward and around the breast. The adult female resembles the male, although she is slightly duller in color with less red on the front of the head.
Like most woodpeckers, the Lewis's Woodpecker has four toes, the first of which is small, the fourth is longer than the third, and the second and third are together at the base. They have large claws which are curved and laterally grooved.
The wings are long spanning to 21 inches. The tail is of medium length and very strong. It has ten feathers that are pointed and stiff. The outside feathers are shorter than the center ones.

Average mass: 115 g.
Other Physical Features: endothermic ; bilateral symmetry
Lewis's Woodpeckers nest in excavated cavities which they may return to for many years. A female Lewis's Woodpecker can lay from five to nine egs in a season, though six to seven eggs are most common. The eggs vary in shape and size, from ovate to rounded. Eggs are white in color. Both sexes incubate the eggs which lasts for about two weeks. The hatchlings leave the nest about three to five weeks after leaving the shell. The infants have huge appetites being very fond of grasshoppers and wild strawberries. When the fledglings leave, each parent takes part of the brood. Both groups stay close to the nesting area for up to ten days. This woodpecker doesn't show as much parental affection as others of the woodpecker family. It doesn't show much emotion toward its young. It will sit close by and watch quietly while its eggs are taken by a predator.
They like to nest in old trees which are either burned or dead. They prefer burned ones which are blackened. They also enjoy large trees which have been broken off high up at about 175 feet. (Bent 1964, Winkler et al. 1995)
