ABSTRACT
Three pairs of American Rough-legged Hawks (Buteo lagopus) were placed together at the Macdonald Raptor Research Centre in March 1974. A 16L:8D photoperiod regime was begun in April. The pair with the greatest exposure to outside disturbance and the most equal temperaments laid five fertile eggs over a period of ten days. Copulation was seen 19 times preceding the first oviposition, 15 times between the first and fifth ovipositions, and 27 times following egg-laying. All eggs were artifically incubated at 37.5 C, 50 to 60 percent humidity. Four hatched. The chicks, two of each sex, were hand-raised successfully.
