The coyote is an extremely secretive animal and is rarely seen in Pennsylvania. Several canids brought to the Section of Mammals for identification in recent years have proven to be coyotes from various parts of the Commonwealth. There have also been several apparent coyote–dog hybrids, also called coydogs, presented for identification. Determinations are based mostly on examination of the skulls.
This species has been extirpated (disappeared) from Pennsylvania since about 1892. Stories about wolf kills persisted through the 1940s.
It is reported that this mammal can climb trees.
The den of the red fox is frequently a converted woodchuck burrow that takes advantage of the multiple exits created by the original inhabitant. Red foxes will dig their own dens or make use of hollow logs as well.
