Figure 1. This Progne chalybea sits on the roof of a church building. Dozens of Gray-breasted Martins could regularly be seen here, at times entering cavities below the tiles or elsewhere in the building. Because of its preference for churches, this swallow was nicknamed "andorinha-católica" (catholic swallow) in Brazil (Sick 1997).To top of page
