Often partially covered by a roof or arch. However, males will sing from ground or from the tops of grass bunches if no taller structure is available. Vegetation structure seems more important than a particular species of plant. Often placed at the base of a plant and is generally well-concealed. Some nests may be in a shallow depression in ground.

However, I could not find any published account of a parasitized nest in California. Management for Western Meadowlarks that provides the most bang for the buck should be concentrated in these four areas. Some information exists that could impact management decisions in California, however it should be pointed out that much of this research comes from the Midwest. Whether Western Meadowlarks are consistent in most ecological aspects in California to other parts of the United States is open to debate. A far smaller percentage of land exists in this fashion in California, however it would be interesting to know how grassland birds do respond to the California version of CRP or similar lands.
