Comments:
Wind NW, light to moderate, gusting over 10mph at the beach, overcast with low clouds/fog above 300 feet, 15C/59F. 10 minute sea watch from Rodeo Beach, followed by a circuit of the main lagoon.

Good day for migrant shorebirds but lower numbers of warblers and other western passerine migrants today - perhaps the wind?
