Corvus brachyrhynchos

The American crow is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America, only absent from the tundra biome.

Movement and weather

Each season it is first heard regularly where daytime highs are around 3°C (typically -4 to 26°C, from 16 areas). That range is wide, so temperature alone does not explain when it turns up.

Over the weeks it was present in the past year, its centre in North America ranged from 39°N in December to 49°N in July, about 1,100 km apart.

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.
