As with many birds, the nest is built exclusively by the female and constructed of twigs and moss, lined with moss and hair. True to their shy and timid nature, the dunnock's nest tends to be built within dense shrubs and hedges.
Dunnock breeding typically begins in April. The incubation period of eggs tends to be between 12-13 days, and then 11-12 fledge days thereafter. Dunnock eggs are around 19mm long and feature a glossy exterior sheen. After hatching, both parents are involved in the feeding of the young. Interestingly, other dunnocks cooperate to feed young dunnocks.
