title: Data from: The evolution of feather coloration and song in Old World orioles (genus Oriolus)

description: What is the tempo and mode of evolution – how fast and in what pattern do
 traits evolve – is a major question of evolutionary biology. Here we
 studied patterns of evolutionary change in visual and acoustic signals in
 Old World orioles. Since producing multiple signals may be costly, we also
 tested whether there was an evolutionary trade-off between the elaboration
 of those two types of signals. We studied 30 Oriolus taxa using
 comparative methods and a recent molecular phylogeny. Morphology and
 plumage hue evolved comparatively slowly, whereas song evolved rapidly.
 Among individual feather patches, the evolutionary rate of color was
 slowest in primaries, which are critical for flapping flight, and fastest
 in patches exposed to observers (mantle and breast). Thus, primaries seem
 to be under functional constraint while the evolution of visually exposed
 patches is perhaps shaped by sexual selection. Song evolution was
 comparatively fast, but also attracted to a single optimum. This may be
 due to selection for signal efficacy, because all orioles inhabit similar
 forested habitats. Only color diversity was best fit by a speciational
 model: the biggest changes in coloration were concentrated at speciation
 events, thus perhaps linked to the evolution of species recognition. Our
 analysis did not reveal any evolutionary trade-off between acoustic and
 visual signals, suggesting that the elaboration of visual and acoustic
 signals in the Old World orioles evolved independently. Our study shows
 that patterns of evolutionary change may be surprisingly complex even
 within a single clade of birds and thus further studies are needed to
 identify general patterns of signal macroevolution.
