Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.
Bird banding is used to study the movement, survival and behavior of birds. The Bird Banding Laboratory Site has links to the value, procedure and history of bird banding, how to report bird bands (English & Spanish), and resources for birders.
Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Describes the Conte Anadromous Fish Laboratory of the Leetown Science Center, which performs research directed towards restoration and protection of anadromous fish with lists of research projects and facilities.
Proposed removal of dams will change the characteristics of stream flow and will affect fish that swim upstream to spawn. A mathematical model of the river flow tells us where the likely problems will be located and how the flow will change.
Using satellite telemetry and field studies to track pintail ducks during spring migration north from California's Central Valley plus pintails in New Mexico and Texas. Includes links to migration maps, journal, duck calls, and field methods.
Review of the size of breeding populations of Giant Canada geese by states in the Mississippi, Atlantic, Central, and Pacific flyways and the management problems caused by rapid increases of local breeding populations.
Links to ornithology programs at Patuxent Wildlife Research Center, Laurel, MD, including large scale survey analysis of bird populations, research tools, datasets and analyses, bird identification, and seasonal bird lists.
Site for the Platte River Program in Nebraska an area that is a critical staging area for migratory waterbirds of the Central Flyway. Includes links to color-infrared aerial photos, 1938 historic aerial photos, and Cottonwood Ranch research site.
Identification manual with colored photos of species of puddle ducks, diving ducks, geese, mergansers, swans, cranes, herons, egrets, pelicans and cormorants. Also includes information on ordering print copy and downloading as *.zip file.
How will the increasing use of wind turbines affect populations of wild birds and bats? This shows which birds and bats we study, and the aspects of their ecology that may be affected by wind energy development.
