Abstract

We report a discovery of black bears (Ursus americanus) consuming seeds of southwestern white pine (Pinus strobiformis) on north slopes of the San Francisco Peaks near Flagstaff, Arizona, in high-elevation, mixed-species conifer forest. In one instance, a bear had obtained seeds from cones excavated from a larder horde made by a red squirrel (Tamiasciurus hudsonicus). Consumption of seeds of southwestern white pine by bears had not been previously documented. This discovery adds to the number of species of pine used by bears for food as well as the geographic range within which the behavior occurs.

Presentamos el descubrimiento de osos negros (Ursus americanus) consumiendo las semillas de pino blanco (Pinus strobiformis) en las laderas norte del cerro San Francisco cerca de Flagstaff, Arizona, en los bosques de alta elevación de coníferas mixtas. En un caso, un oso obtuvo las semillas de los conos excavados de una despensa de la ardilla roja (Tamiasciurus hudsonicus) . El consumo de semillas del pino blanco por los osos no se había documentado previamente. Este descubrimiento aumenta el número de especies de pino utilizadas por los osos para alimentación, así como el rango geográfico en el que ese comportamiento se encuentra.
