The Wrynecks have many of the habits of woodpeckers, but are not so capable 

 of climbing trees, and chiefly fix. on the bark to extract insects from the crevices. 

 They also frequent ants' nests, preying on the ants and their larvse. There are only 

 two foreign species of this genus mentioned by authors, the Y. minutus^ (Picus minu- 

 tusj Lath.,) and a new species from South America.
