    The distribution and abundance of obligate grassland breeding birds in the US have declined across the Great Plains as native habitats have been converted to intensive human land use. A major finding of Scholtz et al. (2017: Table 3) was that the group-wise extinction rate among 13 common grassland nesting birds declined with increasing cropland. This conclusion runs counter to expectations and may be attributable to an artefact of flawed data or analyses. Here, we outline four concerns that may be contributing to the counter-intuitive association.
