The nest looks like an ordinary tuft of green and brown weeds. It is open only on one side, and this entrance may also be hidden by overhanging weeds or by a roofed run. For birds who nest on the ground, in easy reach of predators, concealment is the best defense. Concealment does nothing however to protect them from their worst tiger, the mower. The birds are in the middle of nesting during June and July, and if alfalfa is mowed early, many nests are destroyed.
Meadowlarks are relatively silent while they're nesting and caring for the young.
If you hear a meadowlark resume his singing in summer, you'll know the first brood has probably fledged, and the parents are about to start a second nest. Two species of meadowlarks Not all meadowlarks sing the same song. We have two species in the United States, Eastern Meadowlark and Western Meadowlark. They look almost exactly alike, but their songs are easy to tell apart. The Eastern Meadowlark whistles a melody of about four or five notes.
