Grassland Birds and Killdeer

The video explores the habitat and behavior of grassland birds, focusing on the killdeer. It describes the killdeer's preference for open grasslands over beaches, their tolerance to human activity, and their unique precocial nature. The video explains the advantages and risks of the killdeer's extended incubation period, which results in chicks that are independent soon after hatching. Observations of chick development highlight their growing confidence and independence.
