Sheep Depredation by Golden Eagles in Montana
A limited study on two ranches near Dillon, Montana, near the end of the lambing season in 1974 revealed that 44 domestic lambs were killed by golden eagles (Aquila chrysaetos). This was 76 percent of all deaths recorded during the short study. Using an average docking percent of 90 (based on years before severe eagle problems developed), the 76 percent eagle predation, and the 1974 docking per...
متن کاملMorphometric , Karyotypic , and Laparoscopic Techniques for Determining Sex in Bald Eagles
Willow ptarmigan (Lagopus lagopus lagopus) were censused in late summer for 4 years and broods classified as first, renest, or null (empty) broods. From brood frequencies and clutch size data, estimates were made of egg production, hatching success, survival of young, and contribution to production of each class. Loss of first clutches (N = 231) averaged 27%, and renesting compensated for 43% o...
متن کاملMorphometric sex determination of Milky and Painted Storks in captivity.
Logistic regression was applied to develop a morphometric sexing method of two closely related stork species that were previously sexed through amplification of the CHD gene. Tarsus length (TL) and bill length (BL) measurements were recorded from captive populations of adult Milky Stork (Mycteria cinerea) (n = 60) and Painted Stork (Mycteria leucocephala) (n = 58) at Zoo Negara Malaysia. Despit...
متن کاملFood Consumption and Growth Energetics of Nestling Golden Eagles
AasTaAcT. -Food consumption, energy metabolism, and growth of 12 wild Golden Eagle (Aquilu chrysaetos) chicks were compared with 4 captive chicks to evaluate the influence of food availability and sibling interaction on growth in wild nestlings. Captive female and male eaglets consumed and assimilated similar amounts of black-tailed jack rabbit (Lepus calijbrnicus). A linear relationship betwee...
متن کاملTechniques and Results of Artificial Insemination with Golden Eagles
The techniques and-some of the events involved in the successful artificial insemination and incubation of Golden Eagles (Aquila chrysaetos) at Cornell University during 1972 are summarized. Cooperative insemination techniques (Berry, 1972)were used primarily, as opposed to the traditional forced, massage methods normally used for poultry (see Smyth, 1968). Cooperative insemination requires bir...
