Mortality of prairie falcons during the fledging-dependence period
Article Abstract:
Mortality rates of the prairie falcons during the fledging-dependence period in southwestern Idaho are high, but consistent between the years despite a decline in the primary prey of falcons in 1993. The key cause of mortality is the predation by the great horned owls, in addition to the presence of hematophagous ectoparasites in aeries. Survival is lower during the fledging-dependence period, in contrast to the incubation or the nestling periods.

Numerical and functional responses of migrant Bald Eagles exploiting a seasonally concentrated food source
Article Abstract:
Research is presented concerning the correlation between the population fluctuations of migrant Bald Eagles and the spawning of Kokanee Salmon at the Hauser Reservoir, MT. The correlation was more evident for juvenile Bald Eagles.
