Is the largest bird I have been able to photograph. And it also is one of the pretties one. White herons are statuesque, stately, and elegantly plumaged, with long necks and long legs, herons rank among our most conspicuous and beautiful birds.

These birds have striking red plumage that's thought to play a role in attracting mates. They are known for having this stunning red (and sometimes yellow) color.
To develop red feathers, they need to eat seeds or fruit containing pigment molecules called yellow carotenoids. Their bodies then change those pigments from yellow to red.
