by diving on its prey and will investigate army ant swarms. It beats its catch on the perch before eating it. Its diet is primarily insects and also includes small invertebrates and some fruits.

Breeding The white-necked puffbird's breeding season varies geographically but generally is within the March to September window. Both sexes excavate the nest cavity, usually in an arboreal termitarium or rotting tree. Most nests are about above the ground, but they have been reported as low as and as high as . Holes in the ground and an earth bank have also been reported. The one documented clutch had two eggs. Vocalization Descriptions of the white-necked puffbird's song include "a long bubbling trill, at a constant pitch or rising slightly, then falling" and "an evenly pitched monotonous trill that lasts 3–5 seconds". It also makes "a descending whistle 'wheeew'" call and "a quiet growl." Status The IUCN has assessed the white-necked puffbird as being of Least Concern. It has a very large range and a population of at least 500,000 mature individuals, though the latter is believed to be decreasing.
