Nesting begins in December, and this occurs colonially on forested slopes and cliff sides and often within montane forest at 1,500-2,000 m, though up to 2,300 m in the Dominican Republic. Nest is in a crevice or burrow; on Hispaniola, generally above 1500 m. Nesting birds apparently commute large (10-100km or more?) distances from breeding to foraging sites.

Eggs: 1, white; breeding from November to mid-May.

Nest is a well defined 30 cm diameter cup lined with dry pine needles (Simons et al. 2006).
