Most woodpecker movements can be described as dispersive, such as when young birds seek territories after fledging, or eruptive, to escape harsh weather conditions. Several species are altitudinal migrants, for example the grey-capped pygmy woodpecker, which moves to lowlands from hills during winter. The woodpeckers that do migrate, do so ...

Picinae containing the true woodpeckers is one of four subfamilies that make up the woodpecker family Picidae. True woodpeckers are found over much of the world, but do not occur in Madagascar or Australasia. Woodpeckers gained their English name because of the habit of some species of tapping and pecking noisily on tree trunks with their beaks ...
The Syrian woodpecker lacks its relative's black cheek bar and has whiter underparts and paler red underparts, [11] although juvenile great spotted woodpeckers often have an incomplete cheek bar, so can potentially be misidentified as Syrian. The white-winged woodpecker has a far more extensive white wing patch than the great spotted woodpecker ...
The winter temperatures may have a direct effect on winter survival of lesser spotted woodpeckers by heat loss, whereas weather conditions during spring have an indirect effect on breeding performance by affecting food sources. In 2017, the UK population of lesser spotted woodpeckers was reported to have almost halved since 2009, to around 2,000.
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
Downy woodpeckers nest in a tree cavity excavated by the nesting pair in a dead tree or limb. In the winter, they roost in tree cavities. They tend to nest near soft snags, [18] where the wood is softer and the inner heartwood of the tree can be accessed more easily. The woodpecker will form a nest cavity in the softer heartwood, and its nest ...
