2014-08-07 (548)

There are 19 species of weavers that are thought to be cooperative breeders. For some species, this has been well studied, eg. White-browed Sparrow-weaver, Grey-headed Social-weaver and Sociable Weaver. In these species the young of previous broods help the adults with feeding chicks. Several malimbes cooperate in nest building with adults and young helping.
