Nine-banded armadillos (Dasypus novemcinctus) are found in a wide range of habitats, but always require plenty of cover. In the warmer parts of their range they feed at night. In colder areas they may be spotted during the day, especilly in winter. These armadillos build large nests at the ends of their long burrows. The nests are filled with dried glasses. In areas with plenty of plant cover, nine-banded armadillos may also build their nests above ground.
Nine-banded armadillos search for their animal prey by poking their long noses into crevices and under logs. They also eat fallen fruit and roots. When threatened, the animals waddle to their burrows as fast as possible. If cornered, they will curl up into armoured balls.
Nine-banded armadillos forage alone, but they may share their burrows with several other individuals, all of the same sex. The breeding season is in late summer. Litters of identical same-sex quadruplets are born in the spring.
