Under the name of the “Cuckoo’s Mate” this species is well known in our southern and south-eastern counties. Elsewhere in England it is rare or local, and in Scotland and Ireland it is of very irregular occurrence. The name “Cuckoo’s Mate” is derived from the fact that its arrival usually coincides pretty closely with that of the Cuckoo, namely during the first week in April, but in other respects it has no connection in habits or distribution with the better-known species. Owing to its dull and unobtrusive plumage, and more especially from its custom of inhabiting gardens and woods, it is not easy to see, though to those who know its note, which is a sharp “qui, qui, qui,” its presence will be frequently made known. It feeds chiefly on ants, which it searches for on the ground or on tree-trunks. These are rapidly conveyed to its mouth by a quick motion of its long extensile tongue, which is coated with a sticky mucus, and the rate at which this organ is shot forwards and backwards is almost incredible, and reminds one rather of the tongue in the chameleons and some other lizards. It breeds in the hole of a tree, and the six round white eggs are laid on the wood itself without any attempt at a nest. If the hole be visited during incubation the sitting bird will utter a peculiar hissing noise, and at the same time twist her neck in a most surprising manner. This habit, which is well calculated to make the observer believe the hole to be tenanted by a snake, has given rise to the name of “Snake-bird” as well as the better-known one of Wryneck. The sexes are alike in plumage, the general colour being greyish with dark streaks of brownish black on the nape and scapulars. Throat, upper breast, and flanks yellowish, becoming paler on the belly, with narrow black bars and arrow markings. The young are greyer, and have no yellow or arrow-shaped markings on the under parts. Length 7 in.; wing 3·4 in.

Towards the end of September it takes its departure, but some individuals frequently remain much later, and probably occasionally spend the winter with us.
