  1. We indicate groups used for separate occupancy analysis: ground omnivores and insectivores (GRD), Columbiformes (COL), passerine granivores (GRAN), ground nesters passerine granivores (GRGR), insectivores (INS), and insectivorous aerial foragers and salliers (AER). We also indicate subgroups (g1, g2, g3, g4, g5) for analyses within each group, and total number of observations in field borders (B) and interior (I)
  2. aGroup (guild): 1 = ground omnivores; 2 = ground granivores; 3 = granivore foliage gleaners; 4 = ground nesting granivore foliage gleaners; 5 = insectivorous foliage gleaners; 6 = ground and foliage omnivores; 7 = ground insectivores; 8 = insectivorous salliers; 9 = insectivorous aerial foragers
