A few days ago this colorful heron filled itself with small fish caught from the Cedar River. The bird looks to be a Great Blue Heron based on its bill colors, head and neck feathers. The water's color is due to the reflection of nearby green foliage and seasonal algae.
The expert angler fished in the afternoon sun, below the low head dam at Palisades Kepler State Park near Mount Vernon, Iowa. Apparently unfazed by my approach, the heron made the choice of catching food versus fleeing. Smart bird.
