Species that have a pattern of moving from one geographical area to another, primarily according to the seasons, and usually traveling long distances along established routes.
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.
Studying 28 species of warblers, flycatchers, tanagers, and vireos, we find the birds relied on the flowering of honey mesquite to detect the availability of insects they eat.
Maps and information about potential spread of avian influenza in migratory birds in Alaska. Includes descriptions and photos of the waterfowl that are being monitored.
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.
Experimental use of artificial burrows in south Texas to help in conservation of the migratory burrowing owls (Athene cunicularia) that breed in dry grasslands using animal burrows.
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.
