Birds around Tokyo
Tokyo, Japan
Every measure here is worked out per 5 degree square, so this covers the wider area around Tokyo (35° to 40° latitude, 135° to 140° 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).

Expected in the next six weeks
