Broods, depending on the population, can be raised by a lone female, multiple females with the part-time help of a male, multiple females with full-time help by a male, or by multiple females and multiple males. Unlike most birds, female dunnocks may mate with several males. Parental care and provisioning This multiple mating system leads to the development of sperm competition amongst the male suitors. The species is a favoured host for the cuckoo, which often lays its eggs in the smaller bird’s nest. This last system represents the best case scenario for females, as it helps to ensure maximal care and the success of the young. In pairs, the male and the female invest parental care at similar rates. Dunnock nests are often targeted by cuckoos in the countryside. [15], Dunnocks are territorial and may engage in conflict with other birds that encroach upon their nests. Look out for the species hopping along the ground as it searches for insects. They are frequently targeted by cuckoos, which remove one dunnock egg and replace it with the much larger cuckoo’s egg. Parents must establish breeding territories early on in the year and assert their dominion over them. In territories in which females are able to escape from males, both the alpha and beta males share provisioning equally. Sometimes, two or three adjacent female territories overlap one male territory, and so polygyny is favored, with the male monopolising several females. Over the Autumn months, you'll find seeds and berries a perfect treat for dunnocks, often taking these from bird feeding tables. Dunnocks may not be the most glamorous of birds, but there is more to this species than meets the eye, especially when it comes to mating. These birds can look similar from a distance, but the easiest way to tell them apart is the beak. When resources are distributed in dense patches, female ranges tend to be small and easy for males to monopolise. The cup-shaped nest is lined with moss and hair, and built from twigs and moss. Thus, the mating system can be shifted from one that favours female success (polyandry), to one that promotes male success (monogamy, polygynandry, or polygyny). Females are often polyandrous, breeding with two or more males at once,[20][21] which is quite rare among birds. Dunnock nest and eggs The dunnock builds a nest (predominantly from twigs and moss and lined with soft materials such as wool or feathers), low in a bush or conifer, where adults typically lay three to five unspotted blue eggs. Registered in England No. The Woodland Trust is a charity registered in England and Wales (No. "Food distribution and a variable mating system in the dunnock, Xeno-canto: audio recordings of the dunnock, Ageing and sexing (PDF; 2.0 MB) by Javier Blasco-Zumeta & Gerd-Michael Heinze, https://en.wikipedia.org/w/index.php?title=Dunnock&oldid=977045526, Taxonbars with automatically added original combinations, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 September 2020, at 16:17. It is by far the most widespread member of the accentor family, which otherwise consists of mountain species. He coined the binomial name of Motacilla modularis. Despite the dunnocks’ bright blue eggs looking quite different from the pale, speckled egg of the cuckoo, it doesn’t seem that dunnocks are capable of ejecting these ‘imposter’ eggs. However, sometimes, multiple males will co-operate to defend a single territory containing multiple females. Credit: Stephen Dalton / Alamy Stock Photo. The dunnock (Prunella modularis) is a small passerine, or perching bird, found throughout temperate Europe and into Asian Russia. Dried mealworm works a treat for dunnocks as well. They are roughly the same size as a robin. In times of scarcity, female territories expand to accommodate the lack of resources, causing males to have a more difficult time monopolising females. Interestingly, other dunnocks cooperate to feed young dunnocks. http://www.ornitofaunistika.com/lvp/balsis/prumod_song_A_2007-04-06_0657_valle_a.celmins.mp3. An adult pair generally successfully manages two broods per season. Help us get 50 million trees in the ground. [13][14] Favoured habitats include woodlands, shrubs, gardens, and hedgerows where they typically feed on the ground, often seeking out detritivores as food. 294344) and in Scotland (No. [4], The name "dunnock" comes from the English dun (dingy brown, dark-coloured) and the diminutive ock,[5] and "accentor" is from post-classical Latin and means a person who sings with another. Polyandry, though, is the most common mating system of dunnocks found in nature. A study has found that males tend to not discriminate between their own young and those of another male in polyandrous or polygynandrous systems.
