Détails de l'observation
How the terns have tabled. In recent years, a pelagic-only species for San Francisco. Cold front with rain seemed to ground them and subsequent reports indicated they took off shortly after the weather cleared. Other simultaneous reports of this species roosting further down the coast in San Mateo. Roosting with Elegant and Caspian Terns on the sand inside the lagoon, just off the footbridge. Small terns, red bills with black tips, varying amounts of black in primaries, gray underside, short legs. Some photos indicate a pencil line of black along outer tail feathers.
