The snowy egret is a bird I've seen rarely in Vermont, but frequently down at Parker River Wildlife Refuge. It's about half the size of a great egret and a lot more mobile and it's distinguished by its black beak and yellow feet (I think of them as akin to clown shoes just because of the garish color).
Watching one of these creatures hunt is an entertaining experience. Instead of casually standing still, being very quiet and blending in until it spots prey, it aggressively goes after its prey, but does so with an odd, diagonal, pattern. You can see it stand for a bit then suddenly just dart about five or more feet to grab something out of the water.
This particular picture is from Parker River Wildlife Refuge in Plum Island, MA, but my first sighting of a snowy was in coastal Maine, on a dark and wet day, when we spotted a small group of them on some rocks in a nearby river. At the time, it was true excitement to spot and photograph a new bird for me, but even years later, I love watching them move, dart, weave and bob about.
