FAQ
Frequently Asked Questions
No, it is a type of harrier, which is a distinct group of long-winged, long-tailed raptors in the genus Circus, separate from eagles (Aquila, Haliaeetus, etc.).
The Western Marsh Harrier (Circus aeruginosus) is an Old World species. It is not native to the Americas. North America has its own harrier species, the Northern Harrier (Circus hudsonius), which also frequents marshes.
Historically, habitat loss (drainage of wetlands) and persecution were major threats. Current threats include habitat degradation, disturbance, and, in some areas, illegal poisoning or shooting.
Look for a large, broad-winged raptor with a long tail, often flying low with wings held in a shallow 'V'. Males are pale grey with black wingtips; females and juveniles are predominantly brown with a creamy crown and throat.
