Myrmoderus

These birds are often called “antpittas of the antbird world” because of their rounded bodies, long legs, and habit of spending much of their time on or near the ground. Myrmoderus species include birds such as the ferruginous-backed antbird and the rufous-throated antbird—names that already hint at their warm, earthy colors. Unlike many antbirds that are plain gray or black, Myrmoderus birds often show rich rufous, chestnut, and deep brown tones, giving them a handsome, almost velvety appearance.

Most antbirds are small and somewhat slim, flitting through tangled vegetation. Myrmoderus species, on the other hand, tend to be more compact and sturdy, with a strong, upright stance. They often perch low to the ground with a slightly hunched, alert posture, as if constantly watching for movement among fallen leaves. Their legs are relatively long for antbirds, which helps them walk and hop confidently on the forest floor. In many ways, they behave more like ground-dwelling birds than like typical canopy flycatchers or foliage-gleaners.

Like most antbirds, Myrmoderus species are insect hunters, but they tend to use a very patient, deliberate style. Rather than making long, showy flights, they often search carefully among low branches, roots, and fallen debris, snapping up ants, beetles, and other small invertebrates. Some species will follow army ant swarms, taking advantage of the insects and spiders that try to escape the advancing ants. However, they are usually not the most extreme ant-followers in the antbird family. Instead, they mix ant-swarm feeding with independent foraging, moving quietly through the understory in pairs or small family groups.

In terms of habitat, Myrmoderus species are closely tied to humid tropical forests, especially areas with thick understory, fallen logs, and a rich layer of leaf litter. They are not birds of open country or secondary scrub; they prefer mature, relatively undisturbed forest.
