Avian use and vegetation characteristics of conservation reserve program fields

Article Abstract:

The loss of tallgrass prairie ecosystems in the Midwest has led to a loss of habitat for several wildlife species, including grassland associated bird species. The Conservation Reserve Program (CRP) is said to have major wildlife benefits, and a study compares vegetation and avian use of CRP fields in the cool-season grasses and legumes (CP1) and warm-season native grasses (CP2) fields, to find a link between vegetation characteristics and avian abundances. The study found that CP2 fields were mainly used by higher nesting species such as the dickessel, sedge wren and common yellowthroat, with the CP1 fields providing low vegetation height and low litter depth, favoured by grasshopper sparrows and bobolink. The CRP provides the best chance of a breeding habitat for native prairie birds.

Effects of nest dimensions on use of artificial burrow systems by Burrowing Owls

Article Abstract:

Research is presented concerning the impact which different configurations of artificial burrow systems had on their use by Burrowing Owls in Idaho during 1997 and 1998. The preferred nesting chamber size is discussed.
