Notes on the natural history of the Plains Hognose Snake (Heterodon nasicus) in Minnesota

Abstract

The Plains Hognose Snake (Heterodon nasicus) has been the focus of many studies due, in part, to this species' interesting morphological characteristics and death-feigning behavior. However, significant gaps exist in our understanding  of this species' natural history. Often perceived to be a semi-fossorial species in the literature, our data suggests that this species spends the majority of its time during the active season above ground. In addition, we provide some of the first data on communal hibernation for this species. Also discussed are observations on nocturnality, oophagy, and reproduction. Given that the plain Hognose Snake is imperiled in many of the states and provinces in which it occurs, additional research is needed to better inform in-situ conservation efforts.
