Small, charismatic bird of lowland rainforest. Key field mark is yellow bill, easy to see even in dim light. Usually found near treefall gaps in tall forest, where pairs or small groups sit on hanging vines in the mid-story, darting out after flying insects. More likely than other small jacamars to be seen inside forest. Most common vocalization is a short, accelerating trill, trailing off at end; similar to Green-tailed Jacamar but shorter and buzzier.
