Oftentimes when I come upon a Great Blue Heron fishing in the marsh at dawn, they appear as though they have been there for some time, as if they are nearly finished feeding for the morning. That’s because they may very well be done. Great Blue Herons have specialized rod-type photoreceptors in their eyes which allows them to hunt both day and night!
