Sex-specific relationships between urbanization, parasitism, and plumage coloration in house finches
Historically, studies of condition-dependent signals in animals have been male-centric, but recent work suggests that female ornaments can also communicate individual quality (e.g., disease state, fecundity). There also has been a surge of interest in how urbanization alters signaling traits, but we know little about if and how cities affect signal expression in female animals. We present data of carotenoid-based plumage coloration and coccidian (Isospora spp.) parasite burden in desert and city populations of house finches Haemorhous mexicanus to examine links between urbanization, health state, and feather pigmentation in males and females. In earlier work, we showed that male house finches are less colorful and more parasitized in the city, and we again detected such patterns in this study for males; however, urban females were less colorful, but not more parasitized, than rural females. Moreover, contrary to rural populations, we found that urban birds (regardless of sex) with larger patches of carotenoid coloration were also more heavily infected with coccidia. These results show that urban environments can disrupt condition-dependent color expression and highlight the need for more studies on how cities affect disease and signaling traits in both male and female animals.

Hummingbird Plumage Color Diversity Exceeds the Gamut of all other Birds
<p>A color gamut quantitatively describes the diversity of a taxon's integumentary coloration as seen by a specific organismal visual system. We estimated the plumage color gamut of hummingbirds (Trochilidae), a family known for its diverse barbule structural coloration, using a tetrahedral avian color stimulus space and spectra from a taxonomically diverse sample of 114 species. The spectra sampled occupied 34.2% of the total diversity of colors perceivable by hummingbirds, which suggests constraints on their plumage color production. However, the size of the hummingbird color gamut is equivalent or greater than the previous estimate of the gamut for all birds, making hummingbirds the most diversely colored family of birds known. Using one model of avian visual systems, our new data for hummingbirds increases the avian color gamut by 56%. Our results demonstrate that barbule structural color is the most versatile plumage coloration mechanism, achieving unique highly saturated colors with multi-peak reflectance.</p>

Haemosporidian parasites and incubation period influence plumage coloration in tanagers (Passeriformes: Thraupidae)
<p><span>Birds are visually oriented and use their plumage coloration as an important signaling trait in social communication. Males and females may have different patterns of plumage coloration, a phenomenon known as sexual dichromatism. Because males tend to have more complex plumages, sexual dichromatism is usually attributed to female choice. However, plumage coloration is partly condition-dependent, therefore other selective pressures affecting individuals' success may also drive the evolution of this trait. Here we used tanagers to study the relationships between dichromatism and plumage coloration complexity with parasitism by haemosporidians, investment in reproduction, and life-history traits. We screened blood samples from 2849 birds belonging to 52 tanager species for detecting haemosporidian parasites. We used publicly available data for plumage coloration, bird phylogeny, and life-history traits to run models with plumage dichromatism and complexity in males and females. We found that dichromatism was more pronounced in bird species with higher prevalence of haemosporidian parasites. Lastly, females with high plumage coloration complexity were associated with a longer incubation period. Our results indicate an association between haemosporidian parasites and plumage coloration suggesting that parasites impact mechanisms of both sexual selections, increasing differences between sexes, and social (non-sexual) selection, driving females to develop more complex colorations. </span></p>
Complex plumages spur rapid color diversification in kingfishers (Aves: Alcedinidae)
<p>Colorful signals in nature provide some of the most stunning examples of rapid phenotypic evolution. Yet, studying color pattern evolution has been historically difficult owing to differences in perceptual ability of humans and analytical challenges with studying how complex color patterns evolve. Island systems can provide a natural laboratory for testing hypotheses about the direction and magnitude (i.e., rate) of phenotypic change. A recent study of bird coloration found that the plumages of island species are darker and less complex than continental species. Whether such shifts in plumage complexity are associated with increased rates of color evolution on islands remains unknown. Here, we use geometric morphometric techniques to test the hypothesis that plumage complexity and island insularity interact to influence color diversity in a species-rich and cosmopolitan clade of colorful birds—kingfishers (Aves: Alcedinidae). In particular, we test three predictions: i) plumage complexity enhances interspecific rates of color evolution, ii) plumage complexity is lower on islands, and iii) rates of plumage color evolution are higher within island systems. Our results show that more complex plumages result in more diverse colors among species and that island species have higher rates of color evolution. Importantly, we found that island species did not have more complex plumages than their continental relatives. Thus, complexity may be a key innovation that facilitates response to relaxed (or divergent) selection pressures on islands. Lack of strong support for competition-driving rates of evolution along different color axes hints at an allopatric model of color evolution in which species adapt to local conditions on different islands. This study demonstrates how a truly multivariate treatment of color data can reveal evolutionary patterns that might otherwise go unnoticed.</p>

Vermivora photographs in plumage genomic study
<p><span><span><span><span><span><span><span><span><span><span><span>Hybrids with different combinations of traits can be used to identify the genomic regions that underlie phenotypic characters important to species identity and recognition. Here we explore links between genomic and plumage variation in Blue-winged Warbler x Golden-winged Warbler hybrids, which have traditionally been categorized into two discrete types. "Lawrence's Warbler" hybrids are very yellow overall, similar to Blue-winged Warblers, but exhibit the black throat patch and face mask of Golden-winged Warblers. "Brewster's Warbler" hybrids are similar to Golden-winged Warblers, but lack the black throat patch and face mask and sometimes have yellow on their underparts. Previous studies hypothesized that (1) first generation hybrids are of the Brewster's type and can be distinguished by the amount of yellow on their underparts, and that (2) the throat patch/mask phenotype is consistent with Mendelian inheritance and controlled by variation in a locus near the Agouti signaling protein gene (<i>ASIP</i>). We addressed these hypotheses using whole genome re-sequencing of parental and hybrid individuals. We found that Brewster's hybrids had genomic hybrid index scores that indicate this phenotype can arise by majority ancestry from either parental species, their plumage varied from low-to-high levels of carotenoid pigmentation, and individuals captured in multiple years grew consistently less yellow as they aged. Variation in carotenoid pigmentation showed little relationship with genomic hybrid index and is thus inconsistent with previous hypotheses that first generation hybrids can be distinguished by the amount of yellow in their plumage. Our results also confirm that variation near <i>ASIP </i>underlies the throat patch phenotype, which we refined to a ~10-15 Kb region upstream of the coding sequence. Overall, our results support the notion that traditional categorization of hybrids as either Lawrence's or Brewster's over-simplifies their genomic and continuous variation in carotenoid pigmentation and is based primarily on one discrete trait, which is the throat patch/mask phenotype.</span></span></span></span></span></span></span></span></span></span></span></p>
