Description: Garden warblers are plump birds with a round heads. They are grey-brown with olive upperparts and grey neck. The underparts are pale buff. They have dark brown eyes and a white eye-ring.

Garden warblers have short bills with square ends and a pale base and grey-brown legs and feet. Adult males and females look alike.

Juveniles are similar to adults although their plumage is more olive coloured.

Nesting: Female garden warblers build a cup-shaped nest from grass, leaves and roots which is lined with finer grasses and hairs. It is usually constructed low down in a small tree or bush.

Garden warblers lay 4-5 whitish eggs with olive-brown marks. Both adults incubate the eggs for 11-13 days and the young are fed by both parents. Chicks leave the nest 10 days after hatching and they are independent within another 2 weeks.

Garden warblers’ nests are sometimes parasitized by cuckoos.

Feeding: Garden warbles feed on caterpillars, flies, spiders and worms during breeding season as well as fruits and berries during the autumn and winter.

Where to see them: Despite its name, garden warblers are not often seen in gardens. They arrive in the UK in late April or May and leave in mid-July. They can be found in and near woodland across England, Wales and southern Scotland.
