Animals--13 healthy 3-year-old captive-bred American kestrels
Sexual segregation by habitat in American Kestrels
wintering in southcentral Florida: vegetative structure and responses to differential prey availability.
Representatives from Jersey Central Power & Light (JCP&L), New Jersey Audubon and the New Jersey Division of Fish and Wildlife recently banded four American Kestrel
chicks at a nest box located at the South Branch Wildlife Management Area in Hillsborough, New Jersey.
05, df = 27), while the number of American kestrels
, also a year-round resident, stayed about the same (F = 2.
1600 h, the junior author and two colleagues were present when an adult red-tailed hawk captured and killed an adult female American kestrel
(Falco sparverius) at Lemon Tank, San Clemente Island.
We found that there were significantly fewer American Kestrels
These findings are similar to previous results for VecTest, which also tested well with House Finches (Carpodacus mexicanus), Northern Cardinals (Cardinalis cardinalis), and American Kestrels
(Falco sparverius) (4).
On the other hand, studies of American kestrels
that overwinter in farmlands surrounding Hawk Mountain suggest that recently increased populations of Cooper's and, possibly, sharp-shinned hawks, both of which prey on kestrels, are affecting regional populations of this small falcon (Ardia and Bildstein 1997; Ardia et al.
Seasonal shifts in sex ratios of fledgling American kestrels
(Falco sparverius paulus): the early bird hypothesis.
Other Eastman wildlife habitat projects included establishing a nest box monitoring program for eastern bluebirds, American kestrels
, barn owls, and purple martins; planting wetland vegetation; installing wood duck nest boxes; enhancing a wetland area; planting wildflowers; developing a database of wildlife inventory found on the plant site; and a variety of other projects that enhance and protect wildlife and land on unused Eastman property.
She and her colleagues duplicated the conditions on the platforms by exposing captured American kestrels
to electromagnetic fields (EMFs) of 30 microteslas throughout two breeding seasons.
The commonest commuters, in order of numbers, are Cooper's, sharp-shinned, and red-tailed hawks, and American kestrels
Objective--To evaluate the thermal antinociceptive effects and duration of action of buprenorphine hydrochloride after IM administration to American kestrels
Growth rate was independent of brood size in Eurasian Sparrowhawks (Accipiter nisus; Newton 1978, Moss 1979), American Kestrels
We commend FPL for preserving and expanding nesting sites for the rare Southeastern American Kestrels
at Manatee County's Duette Preserve," said Marianne Korosy, Audubon Florida Important Bird area coordinator.
