The four best models for explaining the response of 1317 tropical and sub-tropical bird species to land-use intensity. (The fit of each model to the data was measured using the AIC, shown here as the difference between the AIC of the model in question and lowest AIC of all models. Traits included in these models were: GL, generation length; MIGR, migratory status; DIET, dietary guild; FORSPEC, whether the species was a forest specialist; MASS, body mass. Response to land-use intensity was modelled as the probability of presence of species in each of three land-use intensities—undisturbed, light and intensive—and, given presence, the abundance ratio in light relative to undisturbed and, intensive relative to undisturbed land use. AIC weights reflect the relative support for each model in terms of AIC values, and were calculated following [1].)

rank	model	AIC difference	AIC weight
1	GL+MIGR+DIET+FORSPEC	0	0.455
2	MASS+GL+MIGR+DIET+FORSPEC	−2.35	0.131
3	MASS+MIGR+DIET+FORSPEC	−2.53	0.124
4	MIGR+DIET+FORSPEC	−2.60	0.057
