This report reveals that the coyote, Canis Iatrans, has recently extended its southern range to Panama. The skin of one adult female coyote killed by hunters at Los Pirales, a farm near Gualaca in Chiriqui Province, western Panama, has been deposited in the Gorgas Memorial Laboratory Vertebrate Collection. Other coyotes have been observed in Alanje, Boquete and Boqueron, other localities of the same province. The probable range of the coyote in Panama is indicated, and the need for an urgent management strategy for this canid in the Republic is also expressed.
