Bonapartes gulls flying around near the shore just below the dam catching fish and fighting.

Dettagli dell'osservazione

Estimate, counting by ones. After about 30 mins about 1/3 got up and headed south. Some were spending time around the mergansers that were diving on the far shore. At one point I watched a merganser with a fish in its mouth and a bonapartes gull was aggressive towards it. Almost riding on his back for a moment. 2025-11-26: Updated 320->380. Took a panoramic picture of the gulls on the water and went back later to get a better count estimate.
