INTRODUCTION

A two-year sign survey to determine river otter (Lutra canadensis) distribution and relative abundance within southeastern Oklahoma was initiated in 1993 (1). During this study, field sign of river otter and other mammals were identified within the river basins of the Little River, the Poteau River, and the San Bois Creek, by using Peterson's Field Guide To Animal Tracks (2).

According to Caire (3), river otter are distributed throughout far southeastern Oklahoma excepting Pushmataha, Choctaw, and Bryan Counties. Two identifications of river otter tracks were made in Pushmataha County during the 1993-1994 survey period: east of Nashoba (NW/4, S20, T1S, R21E) and near Cloudy (NW/4, S14, T3S, R19E). Additionally, Bruce Leland, District Supervisor of the United States Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC), reported two incidental river otter deaths during beaver control activities in the eastern half of Pushmataha County during the surveyed period (pers. comm.): one near Kiamichi in 1993 and one near Honobia in 1994. No further reports of river otter in this county exist with the ODWC.

Previous reports of the long-tailed weasel (Mustela frenata) in Oklahoma are confined to Texas, Cleveland, and Payne Counties (3). Additional observations do not exist within the ODWC. Eleven weasel tracks were identified in this study over 1993 and 1994, within Haskell, Latimer, LeFlore, McCurtain, and Pushmataha Counties; locations are given in Table 1.
