Appendix H. The results are presented of one way ANOVAs testing for differences in the abundance of bird guilds among unlogged forest (P), older logged forest (L89) and recently logged forest (L93).

Canopy foliage gleaning frugivores (F2,34 = 5.233, P = 0.010), canopy foliage gleaning insectivores (F2,34 = 5.234, P = 0.010) and terrestrial insectivores (F2,34 = 5.993, P = 0.006) were significantly (using one way ANOVAs in Statistics for Windows 6.1, Statsoft, Tulsa, USA) more abundant in unlogged than recently logged forest but did not differ significantly between unlogged and older logged or older logged and recently logged forest (Fig. H1). Canopy bark gleaning insectivores (F2,34 = 8.912, P < 0.001) and canopy frugivore/carnivores (F2,34 = 8.525, P < 0.001) were significantly more abundant in unlogged forest than both recently and older logged forest but there was no significant difference in abundance between older logged and recently logged forest. Understorey nectarivores were significantly more abundant in unlogged and recently logged forest than older logged forest (F2,34 = 7.679, P = 0.002) but there was no significant difference between unlogged and recently logged forest. The only guild more abundant in logged forest was the undergrowth insectivore guild, which was significantly more abundant in recently logged and older logged forest than unlogged forest (F2,34 = 14.873, P < 0.001); there was no significant difference in abundance between older logged and recently logged forest. There were no significant differences in abundance among forest types for understory bark gleaning insectivores (F2,34 = 0.0279, P = 0.972), canopy foliage gleaning insectivore/ frugivores (F2,34 = 1.360, P = 0.270), canopy nectarivores (F2,34 = 0.602, P = 0.554), canopy sallying insectivores (F2,34 = 0.443, P = 0.646), understory foliage gleaning insectivores (F2,34 = 1.348, P = 0.273), understory foliage gleaning insectivore/ frugivores (F2,34 = 2.897, P = 0.069), understory sallying insectivores (F2,34 = 1.790, P = 0.182) or understory sallying substrate insectivores (F2,34 = 0.738, P = 0.485).
