2 Tail morphology: climbing tail Top: a honeyguide (Indicatoridae); sister family to Picidae, with no tail modifications. Bottom: a woodpecker with broad, stiff shafts of rectrices, reduced barbs at tips. Subfamily Picinae: ca. 190 species

3 Tail morphology: climbing tail Top: world’s largest toucan (Ramphastidae) with with no tail modifications Bottom: world’s largest woodpecker (Imperial Woodpecker, sadly extinct), with broad, stiff shafts of rectrices, reduced barbs at tips.

4 Tail morphology: climbing tail Top: a woodcreeper (Furnariidae) with broad, stiff shafts of rectrices, reduced barbs at tips. Bottom: a foliage-gleaner (also in Furnariidae), with no tail modifications. Top: a woodcreeper (Furnariidae) with broad, stiff shafts of rectrices, reduced barbs at tips.
