Western Meadowlark

Sturnella neglecta

The western meadowlark is a medium-sized icterid bird, about 20 cm (7.9 in) in length. It is found across western and central North America and is a partial migrant, breeding in western Canada and western United States west of the Great Lakes, and in northern Mexico. In the northern half of the breeding range, the birds migrate south for the winter, while further south they are resident all year. The winter range also extends south and southeast of the breeding range, as far as central Mexico, and east to western Florida. The western meadowlark nests on the ground in open grasslands and shrublands. It feeds on bugs and seeds. The western meadowlark has distinctive calls described as watery or flute-like, which distinguish it from the closely related eastern meadowlark. The western meadowlark is the state bird of six states; in Kansas, Montana, Nebraska, North Dakota, Oregon, and Wyoming. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 14°C (typically 8 to 22°C, from 14 areas). That range is wide, so temperature alone does not explain when it turns up.

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.
