Poster Abstract

American kestrels, Falco sparverius, are a species of small falcon. As a fairly common raptor, they make a reasonable species to monitor relatively easily over the summer months. Though not threatened in the American Northwest, other subspecies of Falco sparverius have been in decline over the past 10 years. By understanding local ecology of these birds, such as nesting behaviors, prey availability, and general movement, we can better understand our population of American kestrel to possibly prevent human impacts to their well-being. The first year of this study was set out to determine a practical research area, learn the habits and movements of local kestrels, and set a base for further study. The study area was conducted in various terrains, farmland, pastures, or wild fields, in Washington County, OR. Researchers banded a total of 29 individuals : 20 adults and 9 nestlings. 10 active nest sites were identified and will be revisited in following years. Stemming from this initial study, senior capstone projects will draw on the techniques learned during its course. Projects are anticipated to study potential contaminant exposure and nesting behavior and evolution of Falco sparverius to create a better artificial nest suited to local conditions.
