Great Blue Herons move slowly and frequently, standing like a statue while stalking prey, photographer Dave Govan notes. A heron strike is lightning fast, using its dagger-like beak. Blue Herons will eat almost anything they can catch and manage to swallow. This heron is feeding on what look like small flounders. Its accuracy is amazing — it never missed during 20 minutes of observation at Picnic Point, Govan says.
