Bucconidae
The puffbirds and their relatives in the family Bucconidae are tropical tree-dwelling insectivorous birds that are found from South America up to Mexico. Together with their closest relatives, the jacamars, they form a divergent lineage within the order Piciformes, though the two families are sometimes elevated to a separate order Galbuliformes. Lacking the iridescent colours of the jacamars, puffbirds are mainly brown, rufous or grey, with large heads, large eyes, and flattened bills with a hooked tip. Their loose, abundant plumage and short tails makes them look stout and puffy, giving rise to the English name of the family. The species range in size from the rufous-capped nunlet, at and , to the white-necked puffbird, at up to and . Taxonomy Puffbirds get their common name from their fluffy plumage. In Spanish, they have been nicknamed ''bobo'' ("dummy") from their propensity to sit motionless waiting for prey. American naturalist Thomas Horsfield defined the Bucconidae in ...

Piciformes
Nine families of largely arboreal birds make up the order Piciformes (), the best-known of them being the Picidae, which includes the woodpeckers and close relatives. The Piciformes contain about 71 living genera with a little over 450 species, of which the Picidae make up about half. In general, the Piciformes are insectivorous, although the barbets and toucans mostly eat fruit and the honeyguides are unique among birds in being able to digest beeswax (although insects make up the bulk of their diet). Nearly all Piciformes have parrot-like zygodactyl feet—two toes forward and two back, an arrangement that has obvious advantages for birds that spend much of their time on tree trunks. An exception are a few species of three-toed woodpeckers. The jacamars aside, Piciformes do not have down feathers at any age, only true feathers. They range in size from the rufous piculet at 8 centimetres in length, and weighing 7 grams, to the toco toucan, at 63 centimetres long, and ...
