The California Condor once ranged throughout the mountains and foothills of the western United States, extreme southwestern Canada, and northwestern Mexico. Its numbers were severely reduced until only 18 remained in the wild by the early 1980's. These were captured and used for a captive breeding program along with offspring of eggs taken earlier from Condor nests. Small numbers of California Condors were recently reintroduced into their former range in southern California and also the Vermilion Cliffs area to the north of the Grand Canyon in Arizona. This California Condor was photographed in 1983 from the Valle Vista Condor Lookout in the Los Padres National Forest in southern California. It was one of six seen that day, which represented one third of the remaining wild population of 18 at that time. Photo taken with a Nikkor 300mm f4.5 ED lens on Kodachrome 64 film. (Date: August 1983)

National symbol of the United States, the adult Bald Eagle, with its dark brown body and all white head and tail, is unmistakable when seen in the field. The Bald Eagle gets its name from the white feathers which cover the head of the adult, making it appear "bald" when seen from a distance. Young birds are dark overall with whitish wing linings and a variable amount of white in the tail. They require 4 to 5 years to attain full adult plumage. The Bald Eagle breeds in Alaska (more than 50% of the total population), northern and eastern Canada, the Northern US states, and Florida. It is always found along lakes, rivers, and coastal areas, often in large concentrations in winter where there is open water. This one was photographed flying at eye level along the Homer spit in Alaska. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 200 film. (Date: June 1989)
