Abstract
Abstract We studied the breeding bird communities of 19 reclaimed surface coal-mine grasslands in southwestern Indiana in 1997–1998, using roadside point counts and off-road transects. The mine grasslands in this study were large, ranging from 110 to 3180 ha in area (median, 590 ha). Although dominated by a few Eurasian grass species, they supported diverse bird communities in which grassland-dependent species were prominent along with grassland-associated and successional scrub species. The mean abundances of species (relative to one another) on roadside and off-road counts were positively correlated. Red-winged Blackbirds (Agelaius phoeniceus), Eastern Meadowlarks (Sturnella magna), and Grasshopper Sparrows (Ammodramus savannarum) were present at >90% of point count locations. Other common species, in descending order, included Dickcissels (Spiza americana), Common Yellowthroats (Geothlypis trichas), Killdeers (Charadrius vociferus), Indigo Buntings (Passerina cyanea), Henslow's Sparrows (Ammodramus hen...
