FIGURE 5. Geographic distribution of Sporophila bouvreuil (yellow triangles) and Sporophila pileata (blue circles) based on specimens, literature and field work. Inset: area of sympatry in the states of Minas Gerais (MG) and São Paulo (SP).
FIGURE 4 in Plumage variability and taxonomy of the Capped Seedeater Sporophila bouvreuil (Aves: Passeriformes: Emberizidae)
FIGURE 4. Map illustrating the geographic distribution of the ventral color patterns of adult male birds in the S. bouvreuil complex. Reddish brown ventral coloration is indicated by yellow triangles, light yellowish brown by blue squares, light gray by green triangles, pale brown by green circles, pinkish gray by red circles. The type localities are indicated by the asterisks: 1: S. b. bouvreuil; 2: S. b. crypta; 3: S. b. saturata; 4: S. b. pileata. Note two character groupings: one formed by S. b. pileata in blue, and the other by S. b. bouvreuil, S. b. saturata and S. b. crypta in orange, showing an area of sympatry in the state of São Paulo.

Urbanisation impacts plumage colouration in a songbird across Europe: evidence from a correlational, experimental, and meta-analytical approach
<p>Urbanisation is increasing rapidly across the globe, transforming landscapes, presenting organisms with novel challenges, shaping phenotypes, and impacting fitness. Urban individuals are claimed to have duller tones in carotenoid-based traits, the so-called ″urban dullness″ phenomenon. However, at the intra-specific level, this generalisation is surprisingly inconsistent and often based on examples from few populations or a limited geographic area. Here, combining correlational, experimental, and meta-analytical results from a common songbird, the great tit (<em>Parus</em> <em>major</em>), we investigated carotenoid-based plumage coloration in urban and forest populations across Europe. We find that, as predicted, urban individuals are paler than forest individuals, although there are large population-specific differences in the magnitude of the urban-forest contrast in colouration. Our meta-analysis indicates a non-significant effect of environmental pollution on carotenoid-based plumage for the species, suggesting that the observed differences across urban populations are not only driven by pollution. Finally, using one region as an example (Malmö, Sweden), we reveal population-specific processes behind plumage colouration differences, which are likely the result of variation in the spatial and temporal distribution of carotenoid-rich resources in anthropogenic environments. Our results provide convincing evidence for consistency on the "urban dullness" phenomenon but highlight that its magnitude depends on local urban characteristics.</p>
