Swainson’s Hawks Are Threatened in California



The Swainson’s Hawk (Buteo swainsoni) is listed as threatened in California.

Its numbers have declined significantly in parts of the western United States; and in the western Canadian prairie, reproduction of the Swainson’s Hawk has dropped since the mid-1980s, following a decline in its main prey species, Richardson’s ground squirrel.

In 1995, satellite telemetry was used for the first time to investigate Swainson Hawk migration; these studies revealed that thousands of these hawks were dying in Argentina as a result of the use of pesticides.
