Bird preferences for fruit size, but not color, vary in accordance with fruit traits along a tropical elevational gradient.

When restricting attack rates only to fruits that were held in the beak (indicating potential dispersal), we found the interaction between fruit size and elevation to again be the most important interaction (GLM holding rates ; Figure 6 ; Table A4 ), although in this case, it was marginally significant overall ( p = .05).

Size and elevation We found avian community‐level fruit size preferences to mirror a decreasing trend in frugivorous bird gape width, suggesting community‐scale trait matching.
