Hummingbirds are known for their distinctive patterns of sexual dimorphism, with many species exhibiting sex-related differences in various ecologically-relevant traits, including sex-specific differences in bill shape. It is generally assumed that such patterns are consistent across all hummingbird lineages, yet many taxa remain understudied. In this study we examined patterns of sexual size and sexual shape dimorphism in bills of 32 of 35 species in the monophyletic Mellisugini lineage. We…

The overall positive association of plumage with BLSD suggests that social status determines priority of access to nectar‐providing flowers, as well as help explain the lek paradox.

Evolution of sexual dimorphism in bill size and shape of hermit hummingbirds (Phaethornithinae): a role for ecological causation

Both raw regressions of traits and phylogenetic independent contrasts supported the prediction that dimorphism in bill curvature of hermits is associated with longer bills, and some evidence indicates that differences between sexes of hermit hummingbirds are associated with differences in the use of food plants.

Rensch’s Rule Crosses the Line: Convergent Allometry of Sexual Size Dimorphism in Hummingbirds and Flower Mites

A common cause is proposed for this convergent pattern of sexual size dimorphism that conforms with Rensch’s rule, which is found in hummingbirds and phoretic flower mites.

Bill Shape and Sexual Shape Dimorphism between Two Species of Temperate Hummingbirds: Black-Chinned Hummingbird (Archilochus alexandri) and Ruby-Throated Hummingbird (A. Colubris)

ABSTRACT. Sexual size dimorphism occurs throughout the animal kingdom, and its ecological and evolutionary causes and implications have been intensively studied. Sex-specific differences in bill

Parallel evolution of character displacement driven by competitive selection in terrestrial salamanders

Findings suggest that the repeated instances of character displacement have evolved in situ in Plethodon jordani and P. teyahalee, and suggest that selection from competitive interactions plays an important role in initiating sympatric morphological divergence in these species, and drives parallel sympatrics Morphological divergence between species.
