In scrub just a few inches above these low-growing shining stars it’s already nesting time for birds such as dunnock, wren and whitethroat. The dunnock, Prunella modularis, is an inconspicuous solitary all-year resident the size of a robin, a warbler with a gentle jingling song and a "tseep" that can become an alarm call. It forages for insects, spiders, and worms shuffling along close to the ground, adding seeds and berries to its winter diet. The quiet plumage of browns, black, and grey provides good camouflage against predators, and is subtly tweedy seen close-up. Known as hedge sparrows to many, they can be distinguished from the distantly related sparrows by their thin pointed bill, notched tail, habit of keep low to the ground, never feeding on bird tables, and frequent wing flicks.
Some overwintering continental dunnocks will leave soon, while low courting flights and aerial chases with quivering wings start here. Females will mate with more than one male, and more than one nest may be built, low in bracken or shrubs, flattish made of twigs, grass, and moss, the shallow cup lined with hair or wool. Two or three clutches of unmarked blue eggs are incubated between April and June; possibly from several males, who may help feed the broods. Sparrowhawks and cats predate the adults and cuckoos favour dunnock nests, cuckoo nestlings pushing dunnock chicks out while accepting food from dunnock parents.
