flocks. Breeding The grey-cheeked nunlet breeds from February to June in Colombia but little else is known about its breeding phenology. The nesting behavior of the entire genus Nonnula is poorly understood, but the rusty-breasted nunlet (N. rubecula) nests in a shallow scrape that it covers with twigs and leaves. That species' clutch size is usually four eggs. Vocalization The grey-cheeked nunlet's song is a "plaintive, measured series of up to 20 notes, 'weeip weeip, weeip...'." Status The IUCN has assessed the grey-cheeked nunlet as being of Least Concern, though its population is estimated to be fewer than 50,000 mature individuals and decreasing. The species is considered uncommon to rare in Panama and generally fairly common in Colombia.
