Anting in weavers

Anting is when birds apply ants to their plumage. Birds select ants in the subfamily Formicinae, which produce formic acid when disturbed. Formic acid is toxic to insects and to many micro-organisms, so anting seems to be part of feather care. Other forms of plumage care are bathing and preening, and even dust-bathing or sun-bathing.

There are 2 types of anting. In passive anting a bird perches on the ground, and lets ants crawl through its plumage. In active anting a bird picks up ants in the bill and “wipes” them through parts of its plumage.

Anting appears to be rare in Africa. For instance, Jack Skead noticed anting only once in 45 years of ornithological field work (the anting bird was a Cape Weaver).

Anting has been recorded in 20 weaver species (Table below), but most of these records are from captive weavers (in particular, the London Zoo). Five weaver species have been recorded as anting in the wild (species illustrated below).

Anting has been recorded in the wild for Village, Cape, Holub’s Golden Weavers, Southern Red Bishop, and Red-billed Quelea

 

Ant species or genus that were used by weavers in the wild are all i the subfamily Formicinae:
