HABITAT DESCRIPTION: |
|
Common throughout the state (Potter et al. 1980). Nests in freshwater or brackish marshes (Ehrlich et al. 1988), shrub swamps, grasslands (Nicholson 1997), lake margins, and other open habitats (Potter et al 1980). At the beginning of the breeding season, males forage primarily in upland meadows and farmlands; once the females arrive on the breeding
grounds, males spend more of their time foraging there (Skutch 1996). In marshes, nests are built near or over water (Ehrlich et al. 1988) in clumps of cattail or in bulrushes, shrubs, or small trees. In upland habitats, nests are placed in sturdy herbaceous plants or occasionally on the ground (Nicholson 1997). Insects are gleaned from (Ehrlich et al. 1988) and
males display on emergent vegetation (Skutch 1996). NATURE SERVE GLOBAL HABITAT COMMENTS: Fresh-water and brackish marshes, bushes and small trees along watercourses, and upland cultivated fields; in migration and winter also in open cultivated lands, plowed fields, pastures and prairie (AOU 1983). BREEDING: Usually nests near
water, in cattails, rushes, sedges; occasionally in shrubs or trees.
