Climbers (Scansores), an old-fashioned popular title for several orders of birds whose feet are mainly adapted for climbing. In many cases two toes are turned forward, and two backward; or it may be that one permanently turned backward is joined in branch grasping by another reversed for the nonce. Parrots (Psittaci), cuckoos (Coccygiformes), woodpeckers (Picarie), &c. are included under this wide and somewhat inexact title.
