Movement and weather

Each season it is first heard regularly where daytime highs are around 13°C (typically 11 to 14°C, from 9 areas). That holds across 15° of latitude, which suggests its timing follows temperature more than the calendar.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
