Dunnock

The Dunnock is the most wide–spread member of the accentor family, which otherwise consists of mountain species.
When I first started watching Birds the Dunnock was found to be Hedge Sparrow in most written literature including the bird books. Mine and many others first the Observer’s Book of British Birds, said “misnamed “Sparrow” as it is no relation of the House-Sparrow or Tree-Sparrow” “correctly named Hedge-Accentor, and also called Dunnock” It was in the 80’s that you found it referred to as Dunnock instead of Hedge Sparrow in most literature.
It’s a bird that on first impressions is a slim version of the House Sparrow in size and very similar colouration when first seen, which is made more confusing by its tendency of moving mouse like under hedges and among the lower branches in thick bushes making a good viewing very difficult. The best pointer is to check the beak for Dunnocks eat insects so have a long slender beak to extract insects from crevices, whilst the Sparrow eating seeds have a thick bulky beak to crack the seeds.
Recent research has revealed how interesting the Dunnocks sex life is, for few are monogamous (one male one female) well most are polygynous (males have more than one female mate) more often seen with Pheasants, or polyandrous (females have more than one male mate) such as Red Neck Phalaropes, this means that both parents are likely to have more than one mate with males often looking after more than one nest, this is believed to be done in the Dunnocks case so the female will have a better gene pool of young and an additional partner to help feed the offspring even if the male is not the father to all.
It is often used as a host by the Cuckoo although this may be a recent association. Other host birds are learning to discriminate between eggs so the Cuckoo has evolved eggs to match the hosts. In the case of the blue Hedge Sparrow egg there is no resemblance to the Cuckoo’s mottled eggs and yet they are still accepted.
