At SeaWorld you get egret conflict. They will steal your $5 trays of fish in a flash. And if your fish toss misses the sea lion's mouth, into the mouth of an egret it will go. Notoriously, Shamu has taken at least one unwary competitor (a pelican) into his mouth.
The fringe benefit, during breeding season, anyway, is regular aigrette displays as snowy egrets try to show each other who's the boss.
I believe the feathers in the bill of the egret up top have been plucked from a fellow egret.
