Resumen:
Burrows and tunnels built by Chaetophractus villosus (Desmarest, 1804) (hairy
armadillo) were studied in a farming area located in the Argentinean pampas, Buenos
Aires Province, Argentina. Fifty-six structures were selected and carefully excavated
for this study. Data on diameter, form, and orientation of the entrance, angle, length,
and depth of the galleries, and spatial distribution of the structures were recorded. The
structures were separated into two types: simple and complex, both located in high
terrain. Simple structures are shorter than complex ones and are built when animals
are in search of food or as temporary shelters. Complex structures are built as home
burrows. The orientation of the entrances of both kinds of burrows is related to the
prevalent wind direction.
