Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison, Eric K. Bollinger
Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison, Eric K. Bollinger
Eric K. Bollinger
We estimated nesting success at real and artificial nests of grassland birds to test the influence of nest type, nest position, and egg size on predation rates. We distributed wicker nests and realistic woven-grass nests baited with a clay egg and either a Northern Bobwhite (Colinus virginianus) egg or a House Sparrow (Passer domesticus) egg in four grasslands that were part of the Conservation Reserve Program in east-central Illinois. Nesting success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nesting success was markedly lower, averaging 39% over the entire nesting cycle and 59% during approximately …
