Employ grazing in non-grassland habitats
A replicated controlled trial in a cottonwood Populus sargentii bottomland in northeast Colorado, USA (Sedgwick & Knopf 1987), found that moderate late-autumn cattle grazing had no impact on breeding densities of six selected migratory songbirds over three study years. Five 16 ha cottonwood floodplain plots were fenced and cattle-grazed in October-November 1982-1984, and five were unmanaged. Analysis focussed on six species dependent on the grass-herb-shrub layer for foraging, nesting, or both: house wren Troglodytes aedon, brown thrasher Toxostoma rufum, American robin Turdus migratorius, common yellowthroat Geothlypis trichas, yellow-breasted chat Icteria virens and rufous-sided towhee Pipilo erythropthalmus.
