These efforts can help with the reproductive success of declining bird species such as American kestrels
, while producing fruit crops attractive to consumers.
The majority of rough-legged hawks, northern harriers and American kestrels
were observed in open grass lands, while most red-tailed hawks were observed along forest edges (Table 2).
For the study, 929 raptors of six species admitted to the center were used including Cooper's Hawk (Accipiter cooperii), Red-tailed Hawk (Buteo jamaicensis), American Kestrel
(Falco sparverius), Eastern Screech-Owl (Otus asio), Great Horned Owl (Bubo virginianus), and Barred Owl (Strix varia).

Sex-related differences in habitat selection in wintering American Kestrels
, Falco sparverius.
Howell and Noone (1992) also observed American kestrels
perching on slowly rotating turbine blades.
Furthermore, the number of studies quantifying parental effort (PE) is scarce: while Wiebe and Bortolotti (1994) did so by observing the amount of food parent American Kestrels
(Falco sparverius) delivered to food-supplemented nests, no one has quantified PE by observing the time parents devote to hunting (hunting effort).
Buprenorphine appears to have a longer duration of action and minimal adverse effects when compared to other opioids in American kestrels
The research team, led by biological sciences professor Julie Heath, will examine American kestrels
and create a modeling system to predict how the reaction of other bird species will be to changes in weather patterns.
Found nowhere on Earth but three of the eight Channel Islands (Santa Barbara, San Clemente, and San Nicolas), the lizards are extremely vulnerable to predation--barn owls and American kestrels
find them especially tasty.
They included three African hawk eagles, four jackal buzzards and two American kestrels
, McDonagh, 27, of Fryer Road, West Heath, could have been jailed for up to seven years after admitting the illegal importation of birds of prey, selling them and two charges of offering birds for sale.
Much to our amazement, we were directly beneath a cut-off limb that served as the perch for what appeared to be four young American kestrels
, who ambled back and forth along the branch more than a little curious what was going on beneath them, not to mention wondering just where in the heck Mom flew off to.
Oral VecTest performed well for small samples of American Kestrels
(Falco sparverius), Northern Cardinals (Cardinalis cardinalis), Common Grackles (Quiscalus quiscula), and House Finches (Carpodacus mexicanus).
In addition to the hawk, rangers have spotted two American kestrels
and 24 other species of birds, as well as bobcats, fox, deer, rabbits and kangaroo rats.
Additional projects include establishing a nest box monitoring program for Eastern bluebirds, American kestrels
, barn owls and purple martins; planting food plots for wildlife, and installing wood duck nest boxes and a variety of other ongoing projects that enhance and protect Eastman's unused land as a habitat for wildlife.
