Laura Erickson's For the Birds

Horneros are ground-feeding birds with an odd “goose-stepping” gait. They feed on a variety of insects, other invertebrates including snails, and vertebrates including toads and small fish. They’re generally found alone or in pairs.

The two forms of this species, the Caribbean and Pacific forms, are believed by some ornithologists to be two different species, though their songs don’t support this. They occur in a wide range of wooded and edge habitats, especially near water, and have extended their range due to deforestation. I’ve seen only the Pacific form (the one pictured), and only in Peru.
