Book Description
To assess the consequences of increased recreational activity on bald eagles (Haliaeetus leucocephalus), we studied factors that influenced their behavior and reproductive success in the Gulkana River basin, Alaska, from 1989 to 1993. Both extrinsic and intrinsic factors were associated with reproductive success. Productivity averaged 0.86 young fledged per occupied territory (SE = 0.05) with 59% nest success (n = 274), but productivity varied among years and subdrainages (P

Book Description
Symbol of power, strength, and freedom, the American bald eagle appears on coins, dollar bills, postage stamps, identification cards, and the presidential seal. It is seen everywhere except in the sky, although that is changing; nearly extinct in 1970, the bald eagle has made a modest comeback. In Eagle’s Plume, Bruce E. Beans recounts the compelling, centuries-old story of the bald eagle’s place in American culture and landscape an its struggle for survival. Reviled by western stockmen as a killer of lambs and calves, the bald eagle has been deified by environmentalists as a reminder of America’s natural heritage. When the great national bird was robbed of its habitat and poisoned with pesticides, federal and environmental groups and local communities rallied to save it. Their heroic efforts are chronicled in the book, which also takes the measure and pulse of the bird that so impressed ancient storytellers.
