The day
as a circle.

Midnight at the top, clockwise around a full day. The outer ring is the bird activity by day, with the burst of the dawn chorus at sunrise. The inner ring is the bats at night. Where the sun sets, the birds hand over. Each ring has its own scale, and you switch by season.

  • Birds by day, peak at dawn
  • Bats at night
  • Sun rise & set

Reading the data honestly

  • Too few days measured, but not enough
  • No sensor not listened here
  • Now current hour

This is the yearly average. Sunrise and sunset shift across the year; the faint band shows that spread.

No bat sensor data in this period (sonar sensor active since 2 April 2026).

Birds by day, bats by night. The handover falls around sunset.
