Nine-Banded Armadillo (Dasypus novemcinctus (Mammalia: Dasypodidae) In Sonora, Mexico

We obtained 23 new records of nine-banded armadillos (Dasypus novemcinctus) in the state of Sonora, Mexico, that extend their known distribution range. Nine-banded armadillos are not well known in Sonora, where their habitat encompasses vegetation types that include tropical thornscrub, a transitional biome between Sonoran desertscrub and tropical deciduous forests, and oak woodland, excluding the Sonoran desertscrub. They occur from 50 to 1,656 m above sea level. Precipitation restricts their distribution to areas with a mean annual precipitation of ≥300 mm; otherwise, they occupy irrigation areas and riparian habitats. It is possible that the range of nine-banded armadillos is expanding in Sonora.
