The northern slaty antshrike's breeding season has not been fully defined but appears to vary geographically. Active nests have been found in different parts of Brazil in August and between
October and December and in August in French Guiana. The species' nest is a cup made from shredded plant fibers

The northern slaty antshrike's song is "an accelerating series of usually 10–15 progressively shorter notes starting with laboured, slow-paced notes that are countable, ending with trill of abrupt uncountable notes often sounding higher in pitch". Its pace varies among the subspecies; that of

Colombia it favors the edges of several forest and woodland types below 600 m (2,000 ft). In Ecuador and Peru it occurs in dryish deciduous woodland, in Ecuador at about 650 m (2,100 ft) and Peru up to 1,200 m

has assessed the northern slaty antshrike as being of Least
Concern. Its population size and trend are not known. No immediate threats have been identified. The nominate subspecies has a large range, is considered fairly common to common, and occurs in many habitat types. Subspecies
635:"should be considered at risk, as their respective geographical ranges are extremely limited, and the dry-forest habitats which they occupy are under intensive pressure from agricultural development". The latter has a very small range and suitable habitat is badly fragmented.
