Barn swallow

It is small and black, with small, pointed bill, with small, short legs. It is charcoal-colored, very black, like the American cherry. It is a warbler, a crier, a constant warbler, an awakener of the sleeping. It is a builder of mud nests in house roofs, in house fronts. It is a traveler, a disappearer; later it comes, in [the month of] Atemoztli. It awakens sleepers, it brings them from their sleep; it warbles, it cries out; it flutters; it cleans itself, beautifies itself; it hurls itself into the water, it bathes itself.
