Figure 1

Standardized effect sizes and 95 confidence intervals of functional, morphological and cognitive traits for predicting territory acquisition in lekking long-billed hermit males. Effect sizes are shown for models on the complete data set, including juveniles (n = 30, blue markers) and the one on the subset of adult males (n = 20, orange markers). Effect sizes with confidence intervals that do not overlap with zero (highlighted by the vertical dashed line) were considered to have an effect on lek territory ownership. Photo (by David McDonald) shows a long-billed hermit visiting a feeder like those used in the spatial memory test.
