meadowlark, any member of the genus Sturnella, belonging to the family Icteridae (order Passeriformes). Meadowlarks are sharp-billed plump birds, 20 to 28 cm (8 to 11 inches) long. The two species in North America look alike: streaked brown above, with yellow breast crossed by a black V and a short tail with distinctive white outer feathers. The eastern, or common, meadowlark (S. magna) ranges from eastern Canada to Brazil, the western meadowlark (S. neglecta) from western Canada to Mexico (introduced to Hawaii). The former has a simple four-note whistle and the latter an intricate fluting. Meadowlarks consume insects in summer and weed seeds in fall and winter. The nest is a grass dome hidden in a field.
The red-breasted meadowlark (Pezites militaris), which occurs from Ecuador southward, and a subtropical relative (P. defilippi) are sometimes grouped with red-breasted blackbirds.
