Migration & Home
Range
Some wildlife travel during different seasons of the
year and times of day. These movements are called migration. Migration
distances may be short or very long depending on the species. This
requires that necessary habitats are available along the route. For
many species, corridors that provide areas for safe travel
are very important during migration. An example of migration
are ducks that nest in the northern United States, but fly
south to warmer climates to find food sources and wetlands
that are not frozen during winter.
Other animals reside in the same area all year. The area of constant use
is referred to as an animal’s home range. For example, in
average habitat, a northern bobwhite spends most of its life on an area of approximately
80 acres. If habitat requirements are met in a smaller area (i.e., the
habitat is better), then the home range would be smaller. In optimum habitat,
a bobwhite may spend most of its life on 40 acres. |
