This, Patuxent Reservoir Big Branch Recreation Area in Dayton, MD, is one of my favorite places too and I love nature watching here. It was just yesterday (Father’s Day) that I was here with my dad and we spotted three King Fishers, a Hawk, a Heron, penty of Turtles and Karp all in the areas where these two photos were taken. The top picture actually was taken of the three King Fishers but my camera phone is too crappy to pick them up. Two were sitting on the branch of the tree that hangs over to and above the water, the third sitting on the sandy bank near it. They were too far away for my camera to pick up.
Herons frequent this part of the Patuxent (right where the photos are taken) as well as the King Fishers. The King Fishers are camera shy but out of the three or four herons that frequent it, all but one are VERY shy in general.
The turtles are unlike the ones I came across at Centennial Lake and will run at the sound of someone in 30 or 40 feet away. I saw at least two species of turtle, one I know was a snapping turtle, the others were smaller and too far away for me to tell.
Karp are still spawning so this is a good time to watch for them near the banks/shores. Earlier this year I saw many more though spawning season then was in higher gear.
