Observation details
They nest at the bottom of the Briones Reservoir Spillway. The photo below only shows a small portion of the nest area. Occasionally somethings triggers the flock to all fly away from the nest area simultaneously, and my maximum count of them at such a time was 40, more if some stayed behind.
