Swamp harriers are opportunistic hunters and scavengers, often seen feeding on roadkill. They build large, bulky nests on the ground in areas with dense vegetation. During breeding season, watch for their spectacular "sky-dancing" courtship displays, featuring dramatic dives and loops.

Look for Swamp harriers in open country, particularly near wetlands, farmland, and coastal areas. They're active throughout the day but are especially visible in the morning and late afternoon. Scan the sky for their slow, circling flight pattern as they hunt close to the ground. Listen for their high-pitched "kee-o" call, often heard during breeding displays.
