Suitable cover is often
one of the most limited habitat elements in backyard habitats.
Over 50 wildlife species in the Midwest use cavities in live
trees (den trees) or dead, standing trees (called snags) for
nesting
and denning cover. Unfortunately, yard management practiced by
many of us does not encourage either of these critical habitat
features needed by cavity nesting wildlife. New developments
often lack an abundance of trees. Even when planted, many of
the tree
species selected for landscaping such as Bradford pear, flowering
crabapple, or ash, do not favor development of natural cavities.
Native hardwoods such as oak, sycamore, and beech trees readily
form natural cavities, but may take many years to do so. While
nest boxes are not a replacement for these species or wildlife
habitat management, they are a great way to supplement natural
cavities, make your backyard more attractive to cavity nesting
species, and complement your landscape design at the same time.
Whether you purchase
nest boxes or build them yourself, a properly maintained nest
box can last for years. You can maximize their
value by installing them at the proper heights and in the proper
locations. They should be located near food, water, and other
cover needed by your desired species. There are a few basic “rules
of thumb” that will help you select and install nesting
structures most beneficial for the wildlife species you wish
to attract in your backyard.
Several Publications are available to assist
you in finding the right nest box or feeder for your situation.
