'''Gerygone''', the 'gerygones', is a genus of
bird in the
Pardalotidae family. The genus ranges from
South East Asia, through
New Guinea and
Australia to
New Zealand and the
Chatham Islands. Most of the species are found in Australia and New Guinea, only one, the
Golden-bellied Gerygone has managed to cross the
Wallace's Line and colonise as far as
Thailand,
Malaysia and the
Philippines.
Gerygones are insectivores which obtain most of their food by gleaning and snatching in the foliage of trees and bushes. They are small, mostly weighing an average of 6-7 g, and show little variation in size across their range, except for the insular
Chatham Island Warbler, which is nearly twice as large as the rest of the genus.
