features
The species is 16 cm tall and weighs between 26 and 27 g. The male is black with the exception of a white interscapular spot, small white dots on the wing covers , white tips of the outer tail feathers and a dark gray rump region. It differs from the other predominantly black birds by the powerful black hook-shaped beak and the small white spots on the shoulder feathers. The underside is pale to light gray. The smaller northern mourning ant catcher ( Cercomacra nigricans ) has characteristic white spots on the tail feathers. In the female, the forehead, cap and sides of the head are blackish-gray, the top, wings and tail are dark gray-brown. The front shoulder feathers have white edges, the wing-coverts white points. The underside is olive-colored, darker towards the chest. The distinctive white dots on the head and chest is a characteristic distinguishing feature. Fledglings look similar to females, but are browner with larger spots.
The species is monotypical .
voice
The call is described as a rapidly increasing sequence of harsh “ehnk” tones ending in a sharp “har!” And as a falling “kow-kow-kow-kow”.
Way of life
The food consists of insects that are searched for up to 15 m close to the ground.
The breeding season in Costa Rica is between February and September. The nest is an open shell fixed with cobwebs, often lined with moss, and hangs on a horizontal branch at a height of 0.5 to 3.5 m. The clutch consists of 2 gray-white eggs with light brown and pale purple colors. During the day both parent birds breed, at night only the female. After 14 days, the chicks hatch and are fed by both adult birds.
Hazardous situation
The stock is not considered to be least concerned .
