At Occoquan National Wildlife Refuge near the shore in a weedy area land side of the path.
First osprey of the year.
Harassing the coots (I think).
A small cloud of ground bees investigating the sand in the early spring sun.
A leaf hopper? Hundreds of these things were flying around, low to the ground, in the leaf litter and on tree trunks. A warm late winter/early spring day irruption.
