Other biodiversity: Restore habitat along watercourses
A replicated site comparison in 2002–2012 in 21 riparian sites in the Central Valley, California, USA, found similar amounts of parasitism by the cowbird Molothrus ater in restored or remnant forest sites. Birds: Similar amounts of parasitism were found in restored or remnant forest sites. Lower parasitism rates were found for spotted towhee Pipilo maculatus (Sacramento River: 26% vs 47%) and red-winged blackbird Agelaius phoeniceus (San Joaquin River: 0% vs 25%) in restored sites, compared to remnant sites, in some comparisons. Methods: Restored sites were formerly farmland, and restoration included planting. Bird nests were observed every three days in April–July (Sacramento River: 1993–2003; San Joaquin River: 2007–2009).
