Abstract

The development of a captive breeding program for the endangered Key Largo woodrat (Neotoma floridana smalli) presents special challenges due to aggressive behavior toward conspecifics, a low reproductive rate, and limited information on estrous cycles. In an effort to identify behavioral predictors of copulation, we observed 17 Key Largo woodrats prior to and during 267 male–female pairing events, 76 of which resulted in copulation. Predictors of copulation include male–female interactions at the door of the tube connecting their enclosures, raspy vocalizations, pre-mounting lordosis, and chasing. A binary logistic regression model based on pre-pairing behaviors correctly predicted the outcome of 78.7% of observed pairing events, and a similar model based on intra-pairing behaviors correctly predicted the outcome of 86.1% of observed pairing events. Behavior-based models may be useful in the management of captive breeding programs for this and other endangered species.
