A juvenile Northern Harrier flies over the open grasses looking for its next meal. The dark chocolate eyes says it’s a female; juvenile males have pale greenish-yellow eyes. By the time of adulthood, the eye color of both sexes gradually change to lemon yellow. It was fascinating to watch this hawk as it would fly low into the strong breezes, hover some, and then land in the grasses. Then it would fly back up and start the process over again. These hawks are unique in that they are the most owl-like of hawks as you can see from the disk-shaped face which work much like an owl’s, and with stiff facial feathers to direct sound to the ears; it uses both vision and sound to capture its prey.
