Migration Patterns of Swainson's Hawks
USGS wildlife biologists Michael Kochert, Mark Fuller, and Linda Schueck will present preliminary information about migration patterns of Swainson’s hawks at the annual meeting of the Western Bird Banding Association in Boise, Idaho on September 6. Swainson’s hawks are medium-sized birds of prey that are found in grasslands and agricultural areas. They migrate more than 6,000 miles every spring and fall between breeding areas in North America and their winter ranges in Argentina. Tracking their migration movements provides important information about timing, habitat use, and stopover sites. Further, it may help to understand the extent to which local nesting birds might be threatened by habitat loss and environmental contaminants.
