These birds are large, but there is little to them. They are skin, bones, and feathers. That’s why you rarely see a decent head on photograph, they disappear.
You must be at an angle to get them (or Great Blues) flying towards you.
Above is an Egret flying into a swamp rookery from the woods. They will drop down from tree top, come in low, and finally climb to the nesting trees.
Below is a series of photographs taken following the Egret as it flew in towards me, finally twisting to climb.
