Great Blue Heron juvenile 9/16/18

Juvenile Great Blue Herons are easy to spot with their dark gray caps and two-toned bills, unlike adults with black and white heads and an all yellowish bill. They belong to the genus Ardea, the great herons, of which there are about a dozen species found inhabiting temperate and tropical wetlands around the globe. Great Blues are perhaps the most stealthy of all the herons, wading very slowly or holding perfectly still before making a lightning strike at fish and other prey. This youngster isn’t yawning, it’s trying to stay cool in the 90ยบ heat by holding its mouth open wide and vibrating its neck muscles in a form of panting called gular fluttering.
