  1. Control predators not on islands for songbirds

    A randomised, replicated and controlled trial conducted over two breeding seasons in North Dakota, USA (Dion et al. 1999), found no significant difference in the daily survival rates of songbird nests at eight sites where medium-sized mammalian nest predators had been removed compared with eight control sites. Species removed were red fox Vulpes vulpes, striped skunk Mephitis mephitis, raccoon Procyon lotor and American badger Taxidea taxus. Observations from artificial nests suggest that compensatory predation by smaller mammal species (such as ground squirrels Spermophilus spp.) may have counteracted any effects of target predator removal.
