Notes from the Field – in cooperation with Dr. Arnaud Desbiez of the Giant Armadillo Project
You may be familiar with the nine-banded armadillo or even the screaming hairy armadillo at the GSC – but did you know there is a giant armadillo? These giants can weigh as much as 70 pounds! Little is known about giant armadillos, but Dr. Arnaud Desbiez’s pioneering work on the Giant Armadillo Project is bringing to light the ecology and biology of these prehistoric-looking creatures. Since 2011, Dr. Arnaud and his team have spent hours seeking out giant armadillos. These unique animals are native to South America, where they spend their days foraging on termites and other insects, worms and spiders.
The Greensboro Science Center is a proud supporter of Dr. Arnaud’s work. His research in Brazil’s Pantanal has proven that giant armadillos are true ecosystem engineers. In other words, they’re organisms who create or modify habitat for the benefit of other organisms. In the case of giant armadillos, they build burrows that provide shelter and cool temperature for other species. Dr. Arnaud’s team uses motion sensing cameras to film burrow entry points. In this way, the team has observed more than 25 other species making use of giant armadillo burrows. Check out these amazing photos from the field that Dr. Arnaud and his team recently shared with us:

What makes these burrows such appealing spaces? They hover around 75 degrees Fahrenheit, while air temperature outside of the burrows can reach highs into the 90’s. The stable environment the burrow provides is appealing to the many species looking to get out of the hot sun. Given the large sizes of giant armadillos and the fact they cannot roll into a ball like other armadillos can, the burrows are large and have gaping entry holes well suited to animals of varying sizes. Giant armadillos are nocturnal, so other animals can stay overnight while the armadillos are away. Also, armadillos don’t remain in the same burrow for long; therefore, other animals can make themselves at home in the abandoned burrows.
