Many of the broadbills are brightly coloured birds that present broad heads, large eyes and a hooked, flat and broad beak. They range from 13 to 28 centimetres in length, and live in the dense canopies of wet forests, allowing them to hide despite their brightly coloured plumage. The plumage of the juveniles eurylaimids are similar to those of the adults, differing in being duller and shorter-winged and shorter-tailed in some cases.
