Armadillo Burrows

Dillo Burrow Characteristics

A study of habitat effect on dillo burrows in Florida and Brazil indicated that burrows of the 9-banded species are fewer and larger in Florida than in Brazil. In Florida, burrows were more numerous in hardwood tree areas than in wetlands and fields or upland pine areas, but did not vary in size in the various habitats. Food sources in the various habitats seemed about the same, so some other factor may be determining burrow density. In Brazil, where the 9-banded species lives in conjunction with D. septemcinctus, the burrows were more numerous and larger in swamp and forest habitats than in grassland or disturbed areas.

Comparison of Burrowing in Brazilian and Floridian Armadillos

In a costal rainforest in Brazil, the burrows were smaller than in Florida, probably because that range included a species that normally makes small burrows.  In Brazil, burrows were larger and more numerous in swamp and forest habitats than in grassland or disturbed areas, suggesting that D. novemcinctus is found primarily in forests and swamps while D. septemcinctus is located in the other areas. This was supported by data from sightings of live animals. In Florida, burrows were more numerous in hardwood hammocks than in wetlands, fields or upland pine areas, but burrow dimensions did not vary across habitat types. In Florida, armadillos were seen more frequently than expected in hammocks and wetlands and less frequently than expected in fields and upland pine areas.
