Lesser Spotted Woodpecker

The lesser spotted woodpecker (Dryobates minor) is the smallest woodpecker in Europe, only about 14–16.5 cm long, with a wingspan of roughly 24–29 cm and an average weight of around 21 g. Its compact size, finely barred black-and-white back and lack of red beneath the tail separate it from the much larger great spotted woodpecker (Dendrocopos major). Adult males have a red crown, while females have a pale crown without red.

The small bill is proportionally less powerful than that of larger woodpeckers, and the species spends much of its time on thin branches, twigs and upper parts of trees that larger woodpeckers use less intensively. Its flight is undulating, and outside the breeding season the bird can be remarkably inconspicuous high in the canopy.

Lesser spotted woodpeckers are strongly associated with mature deciduous woodland, especially landscapes rich in birch, alder, willow, oak and other broadleaved trees. Riverine forest, wet woodland, old parkland, orchards and wooded farmland can all be suitable where there is a continuous supply of old trees, dead branches and decaying wood.

A Swedish study published in 2025 compared 241 landscapes of about 200 ha and found persistent occurrence where roughly 40 ha of high-quality older deciduous forest remained within the landscape. Unlogged deciduous forest was more than twice as strongly associated with occurrence as recently logged deciduous forest. Sites where the species persisted over decades also contained a higher proportion of protected forest.

The diet is dominated by insects and their larvae. During much of the year the bird works along thin dead branches, bark and small twigs, extracting beetle larvae and other wood-associated invertebrates or picking insects from the surface. In spring and summer it also takes caterpillars, aphids, spiders and other prey from foliage and branches.

Its small size allows it to forage far out on slender branches and in the crown, often hanging at unusual angles or upside down. Seeds and berries may occasionally supplement the diet, but animal prey remains the core food source.

In late winter and spring the lesser spotted woodpecker becomes much easier to detect as drumming and calling intensify. Both sexes drum, using rapid bursts on resonant dead branches, while a repeated high-pitched call also carries through the woodland.

A study published in 2009 from a subalpine forest in central Norway found little spatial overlap between male and female feeding areas while chicks were in the nest, suggesting that the adults reduce competition by using different parts of the territory.

Most lesser spotted woodpeckers are resident, but the species is a facultative autumn migrant in Fennoscandia and some individuals make much wider seasonal movements. The scale of these movements varies strongly between years rather than following the regular long-distance migration seen in many songbirds.

A study published in 2016, based on trapping at Lista Bird Observatory in southern Norway from 1990 to 2015, recorded 136 lesser spotted woodpeckers during autumn migration. Ninety-six percent were first-calendar-year birds, and annual numbers at Lista were correlated with counts at Falsterbo Bird Observatory in southern Sweden. Males passed a median of about 14 days earlier than females. The pattern suggests that autumn movements can involve a broad part of the southern Scandinavian population and are driven largely by dispersing young birds.

Pairs excavate a new nesting cavity, usually in soft, dead or decaying wood. Dead and dying trees are particularly important: studies in Britain found lesser spotted woodpeckers more dependent on decayed nest trees than the larger resident woodpeckers. The entrance is small and the cavity is left unlined apart from wood chips produced during excavation.

A ten-year study published in 2000 of marked lesser spotted woodpeckers in 17 territories in southern Sweden found exceptionally strong mate fidelity between years; only 3.4% of pairs whose members survived to the following breeding season changed partner. The mating system was not entirely monogamous, however: in years with the best data, 8.5% of females had simultaneous pair bonds and broods with more than one male, while 2.9% of males had broods with more than one female.

A typical clutch contains 4–6 white eggs. Incubation lasts about 14–15 days and is shared by both adults, while the chicks remain in the cavity for roughly 19–22 days. The Norwegian study from 2009 found the male doing about 65% of nest excavation and 64% of chick feeding, while incubation was divided almost equally between the sexes. The Swedish study also found females ceasing to feed during the final week before fledging in 42% of nests; males then fully compensated, and females could resume care after fledging. The young are normally fed by their parents for about one to two weeks after leaving the nest.

The lesser spotted woodpecker is classified as least concern on the IUCN Red List, but regional trends vary greatly. In Britain the species has disappeared from many former sites since the 1980s, is now Red-listed and had an estimated breeding population of about 600 pairs in 2015.

A British analysis published in 2020 found mean productivity of about 2.6 fledged young per nesting attempt, lower productivity after 1980 than before and starvation as the main recorded cause of chick loss. Warmer springs may further reduce breeding success by shifting the seasonal peak of invertebrate prey. The 2025 Swedish study independently reinforces the importance of maintaining extensive areas of older, unlogged deciduous forest.
