Analyzing Landscape Correlates in American Kestrel Nest Box Occupancy

- The American Kestrel (Falco sparverius) weighs in at about 80-160 grams and is roughly the size of a mourning dove or a blue jay, registering it as one of the smallest raptors in North America (Smallwood et al. 2002, Birds of North America). They are known to be common and widespread in their range, spanning over the entire North American continent-- unfortunately, these birds face a declining ... read morepopulation, with reports showing as much as a 12 percent decline in some regions over a ten year period (USGS Breeding Bird Survey). The causes for these declines are currently unknown, although there is some speculation on causes like habitat loss, pesticide use, predation, and competition from other species like European starlings (Sturnus vulgaris). This study aims to investigate features in the landscape that may correlate with numbers of nesting American kestrel breeding pairs, using nest box data obtained from conservation programs in 4 different states and different land coverage maps using GIS (Geographic Information Systems). By understanding the rates in nest box occupancy in American Kestrels and how features in the landscape can impact their success, we may be able to make better informed decisions about the placement of these nest boxes to better aide their population.read less
