Abstract We examined the influence of vegetation and predator community on nesting success of songbirds in the grasslands of eastern North Dakota, USA. Each year, eight sites were chosen: four were subject to predator removal, and four were non-removal sites. On each site, nests of grassland songbirds were monitored, and simulated nests were used to examine how vegetation characteristics at nests affect nest success. Vegetative characteristics at simulated nests did not differ from those at natural nests, but successful natural nests had greater forb and lesser grass cover than unsuccessful nests, whereas no differences in vegetation were detected between successful and depredated simulated nests. On non-removal sites, small mammals and ground squirrels (Spermophilus sp.) depredated nests in taller and denser cover when compared to nests destroyed by medium-sized mammals and birds. On removal sites, we found no difference in vegetation characteristics of nests depredated by different predator types. However, each group of mammalian predators depredated simulated nests with different vegetation characteristics on removal versus non-removal sites. On sites where predators were removed, small mammals and ground squirrels preyed on simulated nests in shorter vegetation containing fewer forbs, ground squirrels preyed on nests with higher grass cover and lower vertical density, and medium-sized carnivores preyed on nests in taller vegetation. These results support the hypothesis that high predator diversity may reduce the chance of “safe” nest sites, and suggest that the behavior of low-level predators may change when top-level predators are removed.

SummaryThree species of declining grassland songbirds were counted in June transects at 42 south-western Missouri (U.S.A.) prairie preserves managed three different ways: biennial July haying, spring burning on a 1–4 year cycle, and sites both burned and hayed every 2–4 years. Hayed prairies had twice as many Henslow's Sparrows Ammodramus henslowi as burned prairies and 2.5 times as many as sites which had been burned and hayed. Hayed prairies had 59% more Grasshopper Sparrows A. savannarum and 14% more Dickcissels Spiza americana than burned prairies. Fired and hayed sites had 34% higher detection rates of Grasshopper Sparrows than sites only burned and similar numbers of Henslow's Sparrows and Dickcissels as burned sites. The three species summed were 60% more abundant in hayed as in fired or fired and hayed prairies. Henslow's Sparrows increased and Grasshopper Sparrows decreased with time since the last management. Grasshopper Sparrows peaked one year earlier after haying than after burning. Dickcissels did not vary by time since last management. Henslow's Sparrows and Dickcissels were significantly more abundant in larger prairies. Preserve management for these three prairie birds should emphasize biennial to triennial mid-summer haying, instead of burning.
