422:. Along the Pacific slope from Costa Rica south and on the Caribbean slope in Venezuela it occurs in semi-humid forest. In Central America it generally ranges between sea level and 1,250 m (4,100 ft), though in Costa Rica it reaches 2,000 m (6,600 ft). In Colombia it ranges between 1,000 and 2,300 m (3,300 and 7,500 ft). In western Ecuador it mostly occurs between 400 and 1,450 m (1,300 and 4,800 ft) and in the east 900 and 1,700 m (3,000 and 5,600 ft).
447:. It typically forages in dense vegetation mostly between about 1 and 6 m (3 and 20 ft) above the ground, but also on the ground and as high as 12 m (40 ft) above it. It actively seeks prey mostly by gleaning leaves, and also takes prey from clusters of dead leaves, vine tangles, and along branches by gleaning, reaching, lunging, and with short sallies from a perch. It will chase dislodged prey to the ground. There are two records of the species following

The slaty antwren's song is an "upslurred whistle sounding like 'wheet' " that is given as single notes a couple of seconds apart or more quickly as two to four interations. Its calls include a "downslurred nasal whine", the "same type of note turned into nasal 'chirr' by overtones", and "sharp
