The thin-billed catamenia is a small bird with a thin bill. It lives high in the mountains of South America and feeds on plant seeds.
The thin-billed catamenia differs from related species by its uniform coloration without bright spots and a very thin bill. It helps plants spread seeds and serves as food for highland predatory birds.
