Black Crowned Night Heron warning a pair juvenile Snowy Egrets that bad things would happen.
Thinking this matches the Short Billed Dowitcher in faded breeding plumage best but meh.
Even though it is bigger, this Yellow Crowned Night Heron wasted no time in getting out of the way of the Snowy Egret on a squawking rampage.
Always the last one...
This Great Egret had taken off to get away from a challenger.
