Weather Conditions: 62 degrees, little to no wind, 100 percent cloud cover to sun breaking through. The view across the marsh was briefly very sharp until the sun started peeking through. Then the distant views became quickly distorted.

Observation Method: through scope from Island Rd.

Other Activity: Initially 1 osprey was observed incubating in the nest. After panning and checking the other nests a second time, I observed 1 osprey on the post by the nest, but could no longer see the osprey incubating in the nest. The view was getting more distorted at this point, so it is hard to be sure.
