Avian density and productivity studies and analysis on the Pawnee site in 1972
MetadataShow full item record
Accuracy of several avian census methods was investigated on ten 8.1-ha plots and along a 39.4-km roadside count. Methods included spot-mapping, flushing, total counts, ratios, and roadside and Emlen strip count procedures. Another index of breeding activities was obtained through live-trapping, banding, and color-marking. Data were gathered on nesting success, nesting phenology, nest site selectivity, and growth dates for nestlings.
