Bats around Milan

Milan, Lombardy, Italy

Every measure here is worked out per 5 degree square, so this covers the wider area around Milan (45° to 50° latitude, 5° to 10° longitude, about 550 km across), not the city alone. Counts are shares of all bats records in the same weeks, so busier stations do not inflate them (methods).

Arrived in the last four weeks

No bats arrived here in these weeks last year, as far as the records show.

Expected in the next six weeks

No arrivals expected here in the next six weeks, going by last year.

Dates are last year's first regular records after at least six weeks away, with each species' own uncertainty on its page. Each species page can email you when it turns up.
