Parental care and behavior of breeding American Kestrels
(Falco sparverius) in Central Argentina.
The majority of American kestrels
were observed on utility wires while most ospreys were seen on a nest platform (Table 3).
Ducks, Canada geese, American kestrels
, red tail hawks, barn owls, seagulls, sparrows, horned larks, swallows and starlings are commonly found at the Eugene Airport, Stephens said.
On San Clemente Island, American kestrels
vigorously defend nesting territories against red-tailed hawks, often chasing intruders several hundred meters from the area (B.
Some raptors such as Cooper's Hawks, Red-tailed Hawks, and American Kestrels
, however, show minimal sensitivity to urbanization and/or agricultural development (Berry et al., 1998; Boal and Mannan, 1999).
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).
Folks from the Indianapolis Zoo will be showing kids some of their exotic animals, such as spotted pythons, bearded dragons, and American kestrels
Don't forget binoculars: Red-tailed hawks are frequently seen flying over the tidal marsh and grasslands, and you may also see northern harriers, osprey barn owls, American kestrels
, and golden eagles.
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.
