Grassland Bird Abundance Estimates on Reclaimed Surface Mines
The restoration and reclamation of sites previously mined for coal are increasingly being recognized as potential habitat for a number of grassland bird species. These sites are typically planted in a variety of native and non-native grasses as part of the reclamation process. Bird species such as the Henslow's Sparrow (Ammodramus henslowii) and Grasshopper Sparrow (Ammodramus savannarum), which are currently the focus of considerable conservation efforts due to steep population declines, are present at these sites. Accurate and precise estimates of population density are important components of this conservation effort. These results could lead to recommendations about the reclamation process that would further enhance the quality of these sites for grassland birds.

The Effects of Gypsy Moth Management on Non-target Organisms
The most prevalent insecticide used to control forest defoliation by the exotic gypsy moth (Lymantria dispar) is Bacillus thuringiensis. This naturally occurring bacterium is relatively target specific and therefore reduces the mortality of non-target organisms associated with more broad-spectrum insecticides. However it is lethal to the majority of caterpillars that contact the bacterial spores highlighting the concern for threatened and endangered moth and butterfly species as well as concern for species and populations of forest Lepidoptera for which we know little about. Application of Bacillus thuringiensis may also pose a potential problem for the large group of migratory birds that depend on these caterpillars to feed their young during the temperate summer. Our research indicates that this non-target caterpillar reduction had some negative effects on avian reproduction including reduced nestling weights. However, these effects do not appear to be dramatic enough to cause long term population declines for the species we studied. Applications of Bacillus thuringiensis over smaller spatial scales and for short periods of time should not severely limit the breeding productivity of the bird species studied.
