The marsh harrier is a medium-sized bird of prey found in wetlands across Europe, Asia, and Africa. They are known for their long wings and tail, which help them glide gracefully while searching for food. Their diet mainly consists of small mammals, birds, and amphibians, which they hunt from the air or by hovering. These birds are characterized by sexual dimorphism, meaning males and females have different plumage. Males are typically brown with a distinctive pale head, while females are larger and have a more mottled appearance. Marsh harriers are also known for their impressive courtship displays during the breeding season.
