What do wood warblers eat?
These birds enjoy a diet made up of insects, flies and spiders which they pick from vegetation with their delicate beaks.
A woodland songster often heard trilling through the treetops, the wood warbler graces the UK with its rich song during the summer, before migrating to Africa for the winter.
Common name: wood warbler
Scientific name: Phylloscopus sibilatrix
Family: Sylviidae (warblers and allies)
Habitat: upland oakwoods, deciduous woodland
Diet: insects and spiders
Predators: jays are known to take young from nests
Origin: native
The wood warbler is a brightly coloured bird with zesty yellow-green upperparts, darker wings and white underparts. It has a distinctive, bold yellow eye stripe and a broad, short tail. One of the larger warblers, it measures around 12–13cm in length.
Not to be confused with: the willow warbler or the chiffchaff. The wood warbler can be distinguished by the clear division in colour between its yellow breast and white underparts.

The breeding season begins in May, when the female builds a dome-shaped nest close to the ground, usually in a shady area of scrub. Five to seven eggs are laid, and chicks fledge when they are around 13 days old.

Wood warblers migrate to Africa over the winter, arriving back in the UK towards the end of April and leaving again around August time.
The wood warbler’s song has been described as sounding like ‘a spinning coin on a marble slab’.
Wood warblers favour upland oak woods, although they can be found in other woodland as long as mature trees are present. They are found in Wales, parts of England and some areas in Scotland and Ireland.

Look out for them from April to August, and listen out for their trilling, rich song high up in the canopy. It is said to sound similar to a coin being spun on a table top, the sound coming in quick succession until slowing to a sudden stop.

The wood warbler is believed to be in decline in the UK and is now a Red List species of conservation concern. It is unclear why the bird is declining, but research is ongoing.
