Birds' The American peregrine falcon, Falco peregrinus anatum, an endangered bird, was known to have nested in Echo Park in 1972-l973. These birds have been exterminated east of the Rockies in the United States, and in most of eastern Canada during the past 20 years. It is now seriously threatened elsewhere. Although peregrines have not been definitely sighted in Dinosaur N.M. for several years, the area along the river is ideal habitat for them. The possibility of reintroducing peregrines is being explored. Because of climate, topography and availability of food, Dinosaur N.M. would be an excellent location t . t d ., t 2 o 1n ro uce peregr~nes In o. Prairie falcons are found within the monument. Although the data available is inadequate it seems reasonable to assume this bird is falling victim to the same factors causing the decline of the other falcons.3 Canada Geese nest actively along the Green and Yampa Rivers. Most nesting sites are located on river islands in the Canyon of Lodore and Island Park. Several nests have been found on canyon ledges as much as 20 feet above the river. This unusual phenomenon has been of considerable interest to waterfowl v- biologists. Many avian predators occupy this habitat, such as bald and golden eagles, four species of hawk, and Turkey vultures. The ,Green River is a major flyway for migratory waterfowl. Many ducks and geese visit and winter in the area. N.M. 2polish, Torn. "The Introduction of the Peregrine Falcon in the Dinosaur 3 Cox, James A. The Endangered Ones.
