Table 1. Percentage of predicted presence area of Little and Great Bustards in Campo Real 2012 and Calatrava 2009 (corresponding with the evaluation datasets).

	Campo Real		Calatrava
	Little Bustard	Great Bustard	Little Bustard	Great Bustard
Predicted area (%)	72.07	49.73	58.50	54.55
Omission error rate	0.09	0.33	0.21	0.11
P	0.003	0.0375	<0.001	<0.001

Omission error rates (proportion of presence occurrence records of the evaluation dataset that fall in an area predicted as unsuitable for the species) and p-values of one-tailed binomial test for evaluating model performance and significance respectively are provided.
