Bluebird Nesting Box Detection
Acerca de
Without long-term survey data from breeding areas, it is difficult to assess the relative importance of environmental influences on changes in Bluebird populations. Survey data assists in evaluating the effects of long-term, gradual influences (such as decreases in winter food supply, regional changes in pesticide use, or increased nest box availability) on regional Bluebird populations.
