a male(?) Barn Swallow or a baby(?) Barn Swallow (see cuicuitzcatl); or, if referring to a person, a drifter (see Molina)
CUĪCUĪTZCA-TL, Barn Swallow (Hirundo rustica) [FC: 28 Cujcujtzcatl] “It is small and black, with small, pointed bill, with small, short legs. It is charcoal-colored, very black.... It is a warbler, a crier … an awakener of the sleeping. It is a builder of mud nests in house roofs, in house fronts. It is a traveler, a disappearer…. It flutters, it cleans itself, beautifies itself; it hurls itself into the water, it bathes itself.” There are three species of mud-nest building Mexican swallows. The description fits the Barn Swallow best.
