Plumage & appearance

Slate-grey head and underparts, streaked brown upperparts, thin needle-like bill, and reddish-brown legs.

Size & weight

Length: 13-14.5 cm, Wingspan: 19-21 cm, Weight: 14-23 g

Voice — call & song

Song is a thin, high-pitched, hurried, squeaky trill often delivered from a prominent bush or roof top. Call is a high, thin 'tseep'.

Diet & foraging

Invertebrates (especially beetles, spiders, and caterpillars) during spring and summer; seeds and small fruits during autumn and winter. Forages primarily by ground-gleaning.

Habitat

Woodland edges, scrub, hedgerows, parks, and suburban gardens with dense cover.

Migration & movement

Mostly sedentary resident, though northern and eastern populations may move south or west during harsh winters.

Nesting & breeding

Builds a neat cup-shaped nest of twigs, moss, and grass lined with softer materials like hair or wool, hidden low in dense bushes or conifers. Clutch size is typically 4-5 bright turquoise-blue eggs.

Similar species

House Sparrow or Eurasian Tree Sparrow, but distinguished immediately by the Dunnock's slate-grey head and breast, and very fine, pointed insect-eating bill.

Ecological significance

Acts as an insect controller in gardens and woodlands, and serves as a primary host species for the brooding cuckoo in many European habitats.

Conservation status

Least Concern, with a stable and widespread population trend.

Observation tips

Look for them hopping quietly along garden paths, flower beds, or the edges of dense shrubs. They respond well to quiet observation and are often spotted scratching the ground for fallen seeds.

Interesting facts

Dunnocks have a notoriously complex mating system that can involve monogamy, polygyny, polyandry, and even polygynandry all within the same population.
