The Three-toed Jacamar is a small, distinctive jacamar endemic to a small region of the Atlantic forests of southeastern Brazil. It has a brownish head, thickly mottled with thin pale streaks giving it a porcupine-like appearance on the face. It has dull green upperparts, a white breast and belly, and a long dark bill. This species is most often observed in small groups, which perch at various levels and dart out to capture flying insects. It occurs in forest patches, typically near water. Burrows are sometimes attended by groups, suggesting cooperative breeding, and have been recorded in clusters of up to 20 in a single bank. The Three-toed Jacamar is threatened by habitat loss and the loss of suitable nesting sites.
