Birds around San Francisco
San Francisco, California, United States
Every measure here is worked out per 5 degree square, so this covers the wider area around San Francisco (35° to 40° latitude, -125° to -120° longitude, about 550 km across), not the city alone. Counts are shares of all birds records in the same weeks, so busier stations do not inflate them (methods).
