🦩Great Blue Heron
The great blue heron is a large wading bird in the heron family (Ardeidae), common near shores of open water and wetlands over most of North and Central America, as well as Northwestern South America, the Caribbean, and the Galápagos Islands. It is occasionally found in the Azores and is a rare vagrant to Europe. An all-white population found in South Florida and the Florida Keys is known as the great white heron. Debate exists about whether these white birds are a color morph of the great blue heron, a subspecies of it, or an entirely separate species.

NPS: "It stands four feet tall, weighs slightly over four pounds, and has a wingspan of nearly seven feet." (4 ft = 1.22 m). Posture-dependent: ADW instead says "They stand approximately 60 cm tall", an outlier against the c. 1.2 m figure used across .gov pages.
