This family contains a single genus of one species which seems to show affinities, structural and biological, with several other very divergent families and it is therefore difficult to know exactly where to place it. In its breeding habits it is very close to the Sunbirds, Nectariniidae, its nests and eggs being in many respects very like those of the genus Cyrtostomus; the tongue, however, is bifid and is provided with a little brush on each tip. It is divided from the Dicaeidae by having no serrations on the edges of the mandibles. Like Zosterops it is gregarious, haunting bushes and flowers in its search for its insect-food but its nidification is utterly different. On the whole a position between the White-Eyes, Zosteropidae, and the Sunbirds, Nectariniidae, seems most suitable.
In the Chalcopariidae the wing has ten primaries, the first equal to half the second, which is shorter than the third; the fourth and fifth are-longest but very little longer than the third ; the bill has the culmen and commissure gently curved throughout but the lower line of the lower mandible practically straight; the tail of twelve feathers is very slightly graduated; the tarsus is short and scutellated; the tongue bifid and furnished with little tufts; the sexes are dissimilar.
