Table 2: Comparisons of propensity to approach across species.

A base model included sex, age, and condition as predictors; the test models then included species. The best-fit model included species. Reference levels for predictors indicated in table.

Predictor	Estimate	Std. Error	z value	P value
Age (as covariate)	−0.205	0.117	−1.749	0.080
Sex (reference: female)	−1.182	0.816	−1.448	0.148
Condition (refence: barrier)	−0.001	0.766	−0.001	0.999
Species (reference: Barbary)	2.369	1.104	2.146	0.032*
