The Great Blue Heron is America's largest heron and native to
North and Central America. It looks similar to the Grey
Heron of Eurasia, but has a rusty grey neck (instead of
white), russet shoulder patches and russet thighs. It also
has white upper legs and grey lower legs, looking like it is
wearing grey boots. Thanks to Alexandra Makhnina who took
these photos in Costa Rica.
The Great White Heron of Florida/Caribbean is a sub-species
(not the same as the Great White Egret).
