On the left is a Great Egret, on the right a Tricolor,
They appear to both be the same size.
But the Tricolor is in water to his ankles,
And the Great Egret is up to his thighs.
(This picture illustrates the concept that often binoculars, or in this case a camera lens, can distort the size of a bird. I know that Great Egrets are larger than Tricolored Herons, but it wasn't till I looked closely that I could see why they appearer to be the same size.)
