The American egret and the great egret are two distinct species of egrets that are similar in appearance but have some key differences.
The American egret (Ardea alba) is found in the Americas, while the great egret (Ardea alba) is found in many parts of the world, including Europe, Asia, Africa, and Australia.
The American egret is slightly smaller than the great egret, with a height of around 32-41 inches (81-104 cm) and a wingspan of around 52-62 inches (132-157 cm). The great egret has a height of around 39-53 inches (99-135 cm) and a wingspan of around 59-79 inches (150-201 cm).
The American egret has a white body with black legs and feet, and a long, pointed bill that is black with a yellow tip. The great egret has a similar appearance, but its legs and feet are black, and its bill is entirely black.
There is more confusion caused because other common names of great egret includes American egret while there is no other common name of American egret includes great egret.
