  1. Most of the individual burrows observed in the study were detected during both ground and drone surveys of their particular transect. Tables a and b show the numbers of these burrows that were classified as potentially active and/or inactive in each of the two grassy communities. To provide a basis for evaluating agreement of this aspect of the two methods, the marginal proportions in each table were tested for homogeneity using McNemar’s test (see text)
