Weavers generally feed on seeds and insects, although some unusual diet items have been recorded, including small frogs. Four weaver species have been recorded as eating small frogs (from Handbook of the Birds of the World, Vol. 15).

Recently Spectacled Weaver was added to the list as Birdpix record 11090. An adult male Spectacled Weaver snatched a Painted Reed Frog from a bench, and flew up into a tree where it shared the frog with a juvenile (click on the record to see more photos).

Weavers that have been recorded as feeding on small frogs:
Baya Weaver Ploceus philippinus
Black-billed Weaver Ploceus melanogaster
Thick-billed Weaver Amblyospiza albifrons
White-billed Buffalo-Weaver Bubalornis albirostris
Spectacled Weaver Ploceus ocularis
