Different rates of survival and reproduction among individuals within a species underlie patterns of distribution and abundance. Such differences can arise due to differences among sites in the quality of habitat or in the quality of individuals or both. The goal of this research is to investigate the causes and consequences of individual variation in reproductive success in American kestrels (Falco sparverius). I will work along a geographical gradient from Quebec to Georgia. At three locations, I will monitor reproduction and survival as a function of body condition and quality of habitat and conduct intensive behavioral observations to determine what role foraging effort plays in influencing body condition and reproductive success. To test hypotheses, I will experimentally manipulate the number of available nest-sites and handicap adults. The ecological and conservation implications of this research include providing a basis for understanding how species may respond to large-scale changes such as global climate change and smaller scale changes such as habitat loss and fragmentation.
