Gnateaters eat insects. One way they catch insects is to perch in a tree and plung to the ground when an insect is spotted. They then stay on the ground only briefly. They also take insects directly from the tree. Gnateaters are difficult to spot and thus are poorly studied. They are located in Central and South America. They are round, short-tailed, and long-legged birds, They are quite upright when standing.

The members of this family are very closely related to the antbirds of family Thamnophilidae and less closely to the antpittas (Grallariidae) and tapaculos (Rhinocryptidae).

Red-throated caterpillar

The red-throated caterpillar is a species of passerine birds from the caterpillar family. It inhabits undergrowth and shrubbery in eastern Brazil from the north of Rio Grande do Sul to Ceara. Its range also extends to eastern Paraguay and northeastern Argentina, and has recently been reported in Uruguay. This bird is often difficult to catch and spot, however it is more common and less shy than other caterpillars.

The red-throated caterpillar is a small, plump bird, 13 cm long, with a short tail and rather long legs. The plumage is mostly reddish brown. Females have a white gray stripe above the eye that ends on a tuft of feathers. The voice is a series of soft squeaks that gradually become fast and loud. At dusk and dawn, males use flight feathers to create a buzzing sound as soon as they fly over their territory.

The red-throated caterpillar hunts, moving rapidly from one height to another through the undergrowth near the surface of the earth. When a bird notices an insect, it makes a short flight down to the ground or near the upper leaves to catch it.

The nest is built from twigs and moss on a bowl-shaped tree. The female lays two dark-colored oval or slightly conical eggs.

The number of subspecies is unclear, but generally there are three generally accepted: Conopophaga lineata lineata, Conopophaga lineata vulgaris, and Conopophaga lineata cearae. The latter subspecies lives in northeastern Brazil, and differs from other birds in both vocalization and morphology. It has a darker, orange-yellow coloration and is absent or almost absent from the white crescent visible on the upper chest of the remaining subspecies. In the XXI century, it is considered as an independent species of Conopophaga cearae.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
