Eastern Coyote Ecology Study, USA
This project is an addition to a similar study that has been
progressing on Cape Cod for the past five years. In the
study site of Revere, MA and the North Boston Metro area, next
steps include monitoring radio-collared coyotes.
CyberTracker will be used to aid students in tracking and
recording coyote locational data
and social behaviour. This information will then be
transferred into a GIS format (ArcView)
to be used in creating maps and charts of project results. About the Coyote Photo © Jonathan Way The eastern coyote (Canis latrans var.) is a member of the Canidae family. Weighing 30-50 pounds or more, it is the biggest variety of coyote. It is actually believed to be a hybrid between the western coyote and either the red/eastern timber wolf or the gray wolf. Historically the coyote was a resident of the western United States. They colonized the eastern states beginning in the late 1800s/early 1900s. Major factors in this development are thought to be habitat fragmentation into agricultural and suburban areas - which provides plentiful prey opportunities - and an absence of competition from wolves which kill coyotes when given the opportunity. Through natural range expansion, the coyote is thought to have reached northern New England by the 1930’s and 1940’s. It has moved steadily southward, now occupying virtually all suitable habitat in the Northeast. One theory, however, attests that coyotes have always inhabited New England and merely survived at very low densities until the early 1900’s. Data does not support this theory, however, as research has found that coyotes generally are able to colonize new areas very quickly. Therefore, if present in the 1900’s these canids would have undoubtedly been detected shortly afterwards. The other, more accepted theory is that wolves used to be the canid that inhabited the Northeast until they were hunted to extinction in the early 1900’s. Then, as mentioned, the eastern coyote (which probably mated with the few remaining wolves) colonized this area around the 1950s. Coyotes now live in 49 of 50 U.S. states (the island of Hawaii being the exception). They live in all types of habitats from pristine wilderness to urban areas. Despite being very elusive, the coyote’s continent-wide distribution makes them an ideal case study for almost any classroom in the United States. |
