Checked out the Triadelphia Reservoir from the Greenbridge boat ramp and the "pipeline" today.   The most unusual birds were a Bonaparte's Gull and 2 Horned Grebes.   The Bonaparte's Gull was flying with about 20 Ring-billed Gulls and made several passes over the reservoir before disappearing into the clouds.
