“…A general herbivorous diet has arisen multiple times within the theropod lineage (Zanno & Makovicky, 2010) and herbivorous or mixed diets are increasingly prevalent throughout Avialae (Zhou and Zhang 2002; Zhou et al., 2004; Zheng et al., 2011; Li et al., 2014; O'Connor & Zhou, 2020). That said, it is often difficult to place species in one specific dietary category; even living birds that are primarily frugivorous have been reported to occasionally prey on vertebrates, including other birds (e.g., Mahecha et al., 2018). Therefore, diet should not be considered a straightforward indicator for carotenoid coloration, but rather a potential guide to its likelihood along with other factors.…”

Carotenoids are pigments responsible for most bright yellow, red, and orange hues in birds. Their distribution has been investigated in avian plumage, but the evolution of their expression in skin and other integumentary structures has not been approached in detail. Here, we investigate the expression of carotenoid-consistent coloration across tissue types in all extant, nonpasserine species (n = 4022) and archelosaur outgroups in a phylogenetic framework. We collect dietary data for a subset of birds and investigate how dietary carotenoid intake may relate to carotenoid expression in various tissues. We find that carotenoid-consistent expression in skin or nonplumage keratin has a 50% probability of being present in the most recent common ancestor of Archosauria. Skin expression has a similar probability at the base of the avian crown clade, but plumage expression is unambiguously absentin that ancestor and shows hundreds of independent gains within nonpasserine neognaths, consistent with previous studies. Although our data do not support a strict sequence of tissue expression in nonpasserine birds, we find support that expression of carotenoid-consistent color in nonplumage integument structures might evolve in a correlated manner and feathers are rarely the only region of expression. Taxa with diets high in carotenoid content also show expression in more body regions and tissue types. Our results may inform targeted assays for carotenoids in tissues other than feathers, and expectations of these pigments in nonavian dinosaurs. In extinct groups, bare-skin regions and the rhamphotheca, especially in species with diets rich in plants, may express these pigments, which are not expected in feathers or feather homologues.

“…Although there is some evidence that predators eavesdrop on prey signaling behaviors (Ryan et al 1982;Mougeot and Bretagnolle 2000), there is no information on whether predators eavesdrop on signaling during contests or on any prey contest cue. In addition, there is no direct evidence about whether escalated fighting increases predation risk in birds, maybe because it is difficult to observe predation on adult birds (Ricklefs 1969;Gotmark and Post 1996;Mahecha et al 2018) which could coincide with an escalated fighting event. Here, I describe a predation event of a possibly injured or fatigued adult Rufous Hornero (Furnarius rufus) by an Aplomado Falcon (Falco femoralis), immediately after a severe contest between two horneros on the ground.…”

Predation risk is often hypothesized to be a cost of escalated fighting, and it relies on the assumption that predators eavesdrop on distracted prey. However, there is no direct evidence supporting these two ideas. Here, I report a predation event that occurred immediately after escalated fighting in birds. Two Rufous Horneros (Furnarius rufus) were engaged in a contest on the ground, while a third hornero watched from a close by (~3 m) perch. The hornero that won the contest, having strongly pecked its opponent, then joined the third hornero on the perch. The loser hornero appeared to be injured or fatigued after fighting and crouched motionless, wings down, and belly touching the ground. Approximately 10 s after the fight, a large Aplomado Falcon (Falco femoralis) suddenly flew toward the loser hornero, caught the bird, and flew away. This casual predation record indicates the falcon was eavesdropping on these horneros' contest, possibly using the opportunity to attack the loser hornero which, due to being injured or fatigued after the contest, was more vulnerable to predation. This anecdotal evidence indicates the existence of a predation cost associated with escalated fighting, stressing the importance of natural history records in animal behavior research.

“…This essentially frugivorous species exhibits a striking sexual dimorphism (Show 1982). The male is characterized by a fan-shaped crest and brilliant orange plumage, while the female displays browner colors (Mahecha et al 2018). Males spend much of their time displaying at leks where females select the one with which they will mate (Show 1982;Mahecha et al 2018).…”

Rupicola peruvianus Latham, known as the Andean Cock-of-the-Rock or locally as Tunqui, is distributed in the Andean cloud forests of South America from Venezuela to Bolivia. Here, we contribute to the bioinformatics and evolutionary systematics of the Cotingidae by performing high-throughput sequencing analysis on R. peruvianus from Luya, Amazonas, Peru. The R. peruvianus mitogenome is 17,035 base pairs (bp) in length and contains 37 genes (GenBank accession No. MN602289). The mitogenome is similar in structure and content to published mitogenomes from the neognathid orders Passeriformes and Falconiformes. Phylogenomic analysis of the R. peruvianus mitogenome situates it in a clade with the Pipridae, sister to the Tyrannidae. We anticipate that further mitogenome sequencing of the parvorder Tyrannida will improve the phylogenetic resolution and our understanding of the evolutionary history of this taxon.
