Construction projects have potential to result in “take” of the California threatened Swainson’s hawk (Buteo swainsoni) when activities occur near active nests. Our analysis examines nest occupancy, reproductive success, and disturbance responses relative to adjacent development intensity. In 2000, the Swainson’s Hawk Technical Advisory Committee established recommended timing and methodologies for identifying and monitoring Swainson’s hawk nests in California’s Central Valley. They identified various levels of risk of projects based on several factors including reproductive success of individuals, long-term survivability of populations, and normal site characteristics. An Incidental Take Permit (ITP) from the California Department of Fish and Wildlife Service is generally recommended if there is a high potential for a project to result in “take” of Swainson’s hawks. When an ITP is obtained, full-time monitoring of the nest is generally required by the California Department of Fish and Wildlife. Often other lower risk nests within 0.5-mile of a project are also monitored full-time but sometimes only on a weekly basis. We summarize findings from 14 nest monitoring efforts at nests within 0.5-mile of projects from 2014-2025. We found no indications that construction activities negatively affected nest success at any of the 14 nests that were monitored.
