Eastern Meadowlark

Sturnella magna

The eastern meadowlark is a medium-sized icterid bird, very similar in appearance to its sister species, the western meadowlark. It occurs from eastern North America to northern South America, where it is also most widespread in the east. The Chihuahuan meadowlark was formerly considered to be conspecific with the eastern meadowlark. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 13°C (typically 8 to 25°C, from 22 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 28°N in March to 38°N in April, 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.
