Then, of forms which are but weakly represented, we have the otherwise abundant thrushes (Turdidae), and, above all, the woodpeckers (Picidae), of which only very few species, out of 400, just cross the boundary and occur in Lombok, Celebes or the Moluccas, but are unknown elsewhere in the region."
Picidae, woodpeckers, cosmopolitan, excepting Madagascar and Australian region.
They compose the family Rhamphastidae of Coraciiform birds, and are associated with the woodpeckers (Picidae) and puff-birds and jacamars (Galbulidae); their nearest allies perhaps exist among the Capitonidae, but none of these is believed to have the long feather-like tongue which is so characteristic of the toucans, and is, so far as known, possessed besides only by the Momotidae (see MoTMOT).
