, orioles, and others, the meadowlark does not travel in large flocks, and it eats harmful insects rather than grain. The eastern meadowlark, Sturnella magna, known for its clear, whistling song, is about 10 in. (25 cm) long. In color, it is brown streaked with black above and yellow below with a broad black crescent across the chest. The Western species, Sturnella neglecta, is slightly smaller, and its call is lower. Recent experiments have shown that the two species do not interbreed in the wild, although they are nearly indistinguishable. Meadowlarks are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
