A study in 1999-2000 on the reclaimed Chinook mine (39-67 ha) and Universal mine sites in southwest Indiana, USA (Galligan et al. 2006), found 465 bird nests of 31 species at Chinook and 446 at Universal. Red-winged blackbird, eastern meadowlark, field sparrow, dickcissel, grasshopper sparrow and Henslow's sparrow were the commonest nesting birds. Reproductive success (i.e. nests that fledged young) of key species, e.g. Henslow's sparrow (9 of 21 nests fledged young) and grasshopper sparrow (26 of 41), and of several other species was comparable with that in non-mined grassland habitats. Both sites were seeded with (mostly) non-native grasses and were situated in open grassland; shrub/savanna; and grassland with patches of shrubs.
