There is little information on the behavior of pihas away from leks. Sometimes pihas are observed at fruiting trees, where fruit is taken with a sally.

Within leks, males have fairly large territories that they maintain through daily calling and movement. Snow (1961) observed a territory of 35 x 75 m.

The population density at one site in southeastern Peru was estimated as 20 individuals/100 ha (Terborgh et al. 1990); Thiollay (1994) estimated a similar density, 22 individuals/100 ha, at a site in French Guiana.

Males gather to form leks and call to attract females. Leks typically consist of (4-10) males, but up to 30 individuals per lek have been found (Snow 1982). Screaming Pihas have not been observed to display visually.

Away from leks, Screaming Pihas usually are solitary.
