Great Blue Herons are basically birds of prey. They love a gopher or two or six. And like Hawks and Owls, they too cough up pellets of indigestible material. Ladies and gentlemen, I present you...
The Park Service has cut down a lot of trees at Crissy Field that were once frequented by hunting hawks. Thankfully the few that remain have still got some hawk attracting properties. The other evening I saw a Red-tailed Hawk bank in the setting sunlight and land to survey the gopher strewn grass below. Above, it leaps into action when it spots something moving in distant taller grasses.
Snowy Egrets can often be seen foraging together in scattered groups but there is inevitably some tension and competition. When an egret decides it has had enough it isn't shy about showing its displeasure.
