In addition, territory quality should be correlated with individual quality because higher quality resident kestrels should be able to defend higher quality territories.
The objectives of my proposed study of American Kestrels will be to examine possible relationships among and between hunting behavior, territory quality, and individual quality in male and female American Kestrels.
The results of this study will provide important information about habitat and perch selection by American Kestrels in central Kentucky in addition to the possible role of individual quality on hunting behavior and habitat use.
Methods Field work will take place from 15 October 2000 through at the Blue Grass Army Depot, Madison Co., Kentucky. Proximate basis of variation in carotenoid pigmentation in male House Finches.
Differential habitat use occurred only because migratory female kestrels usually arrived on wintering areas before males and, therefore, were more likely to establish territories in the better quality, more open habitats before males arrived (Smallwood 1988).
In central Kentucky, many American Kestrels are residents.
During the study period, I will search for American Kestrels throughout accessible portions of the depot.
Searches will be conducted on foot as well by automobile. Plumage coloration is a sexually selected indicator of male quality.
As a result, male and female kestrels would likely have equal opportunity to establish winter territories in the higher quality, open habitats. Plumage colour signals nutritional condition in the House Finch.
If so, habitat segregation should be less apparent in central Kentucky than in areas further south where wintering populations of kestrels are largely migratory.
