The species Dendrocopos minor, Dryobates mino, and Lesser spotted woodpecker have three subspecies。
Small spotted woodpecker is a resident bird. It often acts alone except during the breeding period, feeding on the thick branches and leaves of trees. It mostly acts and roosts in the middle and upper layers of forests, and rarely acts and forages along the trunk. Sometimes they sing along the branches while foraging, and the sound is monosyllabic, like "zha-zha-zha". Flying fast, two wings a close, into a wave forward. Peckers with larger tapping sounds are slow and weak. It feeds mainly on adult and larva of longicorn, silverfish, coleoptera and diptera insects, ants, aphids, flies and other insects.
The breeding season of the small spotted woodpecker is from May to June. Mating and courtship began in early April. The male often chases the female through the forest canopy, making a series of short, loud calls called "ga-ga-ga-". Nest in the hole of broad-leaved trees, nest holes by male and female birds, generally choose to decay in the heart of the tree on the tree. Instead of using the old nest, you have to re-peck the nest hole every year. The hole is mostly round or nearly round, 3-9 meters high from the ground. The diameter of the opening is 2.6-3.2 mm, the inner diameter of the hole is 6-13 cm, and the depth of the hole is 16-22 cm. There are no upholstery inside the nest, only a few wood chips. Each clutch lays 3-8 eggs, white, oval. Male and female birds take turns incubating the eggs, which hatch for 14 days. The chicks are late sex, and the male and female parents feed the chicks together, and after about 21 days of feeding, the chicks can leave the nest to fly。
