Amblyospiza albifrons (Thick-billed Weaver)

Wikipedia Abstract

The thick-billed weaver or grosbeak weaver (Amblyospiza albifrons) is a distinctive and bold species of weaver bird that is native to the Afrotropics. It is monotypic within the genus Amblyospiza. They have particularly strong mandibles, which are employed to extricate the seeds in nutlets and drupes, and their songs are comparatively unmusical and harsh. Their colonial nests are readily distinguishable from those of other weavers, due to their form and placement, and the fine strands used in their construction.
