Population trend and distribution

A scarce and local breeding resident in all counties, principally in the lowlands and along the main river valleys (Lovegrove et al. 1996). Although lesser spotted woodpeckers extended their Welsh range through the 20th century they have rapidly declined in the UK in the last 25 years. The RWBS showed declines of 58.9% (the RSPB) and 43.6% (BTO) in the UK since the 1980s (Amar et al. 2006).

Species requirements

General: mature oak woodland with dead and decaying trees is favoured, including riparian woodland and parkland with larger woodland patches. Lesser spotted

woodpeckers occur at low density even in optimum habitat, eg one pair per 30 ha.

Nesting: nests are preferentially located closer to the woodland edge and located in self-excavated holes, usually high, eg up to 25 m above the ground in the dead side- branches of larger trees. The upper trunk of smaller trees, eg birch, rowan, willow and alder is also used. Nests are sometimes located as low as 1 m above the ground.

Feeding: feeding is almost exclusively on insects, particularly butterfly and moth larvae and aphids. In summer, they forage externally on tree-trunks, branches, twigs and leaves. In winter, beetle larvae and adults are excavated from deadwood, usually in smaller branches and higher in the crown than great spotted woodpeckers. Insects are sometimes caught on the wing and fruit is

18 Rapid (>50%) decline in UK breeding population over the last 25 years with no evidence to suggest that the Welsh population has not declined in parallel. 19 Preliminary assessment for 2008 revision of The Population Status of Birds in Wales: Red-listed.
