The first objective of the present study was to determine whether peregrine falcons (Falco peregrinus) and brown goshawks (Accipiter fasciatus) actively flown using traditional falconry techniques were more fit than cage-exercised birds.
Earle signed a law protecting all raptors, excepting the three species of "bird-killing" accipiters and two species of owls, the great homed owl and the snowy owl (Nyctea scandiaca) (Kosak 1995).
Thirty-five years of conservation and education efforts at the Sanctuary, in part, resulted in statewide, year-round protection for all diurnal birds of prey, including the three "bird-killing" accipiters, in 1969 (Senner 1984).
Bats have been observed falling below the strike of attacking accipiters and falcons and recovering to avoid capture (Byre, 1990), similar to what we observed.

Examining seasonal patterns of space use to gauge how an accipiter
responds to urbanization.
The Eurasian sparrowhawk Accipiter
nisus and black kite Milvus migrans commonly found in open woodlands, marshes, desert grassland, partially cleared lands, and cultivated fields.
Proximity to active Accipiter
nests reduces nest predation of Black-chinned Hummingbirds.
