Here is a snowy egret, photographed on Siesta Key, mid 1980's, with film. Someone asked if this was processed/printed on fabric but no, this was actually roller-scanned from a print way back when....
Meanwhile, this is a more recent image, home home on the nest... What a great 'hairstyle' and attitude of these young snowy egret chicks:
You can tell a snowy egret from a great egret or a (white variation) blue heron by its combination of black legs and yellow "slippers".
Here is a short video clip (more recent, 4k video, 2019) where you can see both the coloring as well as typical behavior, spotting and spearing a fish.
Below is an adult Great Egret, in spring (breeding) plumage, the fine plumes ("aigrettes") once so highly sought for fashion-wear that these birds nearly became extinct.
