The marsh harriers are birds of prey of the harrier subfamily. They are medium-sized raptors and the largest and broadest-winged harriers. A migratory raptor that visits Indian and Africa from Europe and Asia during winters. These harriers glide low just above the grassland and make a quick dive to feed on frog, fish, insects and birds. The adult female is identified by the pale crown. This image was made as the bird was preening and a small feather is seen on one of the eyes as a result of the preening activity.
