Development
of Great Lakes Environmental Indicators Based on Birds
The Great
Lakes basin is one of North America's richest areas of breeding songbirds.
This makes avian-based monitoring programs particularly important for
this region.
Birds contribute
unique information about ecological conditions. Bird populations are sensitive
to fairly large-scale stresses like landscape degradation, and many bird
species are predators of other animals or of insects. The combined effect
of stressors such as habitat alteration, water contamination, lake level
changes, and suburban predators like raccoons and skunk may contribute
to bird population declines.
Many species
of wetland birds in the Great Lakes region are listed as endangered, threatened,
or of special concern in one or more states. Examples include king and
yellow rails, common moorhen, least and American bitterns, osprey, piping
plover, and Caspian, common, Forster's and least terns. We will identify
the ways in which bird communities along the Great Lakes shoreline are
impacted by human activities.
