Figure 1 in A new genus for Thalurania ridgwayi (Trochilidae)
Figure 1. External morphology of males (upper row) and females (lower row) of 'Thalurania' ridgwayi and the four species of Eupherusa, illustrating the forked blue tail, lack of a distinct red patch on the secondaries and tertials, and lack of white in the tail of the former.

FIGURE 2 in New range limit of the Anopetia gounellei (Aves: Trochilidae): state of art and a review on the updated area
FIGURE 2: Updated distributional range limit of Anopetia gounellei overlapped with the dry ecoregions; others ecoregions were avoided for the sake of clarity. The range is not restricted to the Caatinga ecoregion, going beyond it by more than 212,000 km². However, few records are outside the dry ecoregion limits, and even they are close to their limits
FIGURE 1 in New range limit of the Anopetia gounellei (Aves: Trochilidae): state of art and a review on the updated area
FIGURE 1: Updated distributional range of Anopetia gounellei overlaid with the older range limit, the Caatinga biome (by Ministério do Meio Ambiente, Brazil) and the presence records. The occurrence was expanded over 400.000 km² and records from 2010 to 2015 (the year after the first record outside the range limit) are spread over the north-south and east-west limits. It is possible to observe on the south and southwestern areas of the range many records outside the Caatinga biome limit
North American Trochilidae Occurrence Data Filtered from GBIF
<p>This is a filtered dataset from GBIF including all Trochilidae observations identified to the species level in the North American range. Data was downloaded using rgbif::occ_download and accessed from R via rgbif (https://github.com/ropensci/rgbif) on 2024-11-10. The original unfiltered GBIF occurrences can be download at https://doi.org/10.15468/dl.ekuew6, and https://api.gbif.org/v1/occurrence/download/request/0005475-241107131044228.zip. The data is filtered to have coordinates in North America, no geospatial issues, no duplicates across species and coordinates, no coordinate uncertainty greater than 1 kilometer, and no occurrences lying within 1km of a college or university. This dataset is incomplete as it does not include ALL observations that occur in North American countries as observations lacking a continent field of "north_america" in GBIF are not included. The data was uploaded to Zenodo after filtering with the following DOI: 10.5281/zenodo.14062667.<br> </p>
Interspecific hybridization explains rapid gorget color divergence in Heliodoxa hummingbirds (Aves: Trochilidae)
Hybridization is a known source of morphological, functional, and communicative signal novelty in many organisms. Although diverse mechanisms of established novel ornamentation have been identified in natural populations, we lack an understanding of hybridization effects across levels of biological scales and upon phylogenies. Hummingbirds display diverse structural colors resulting from coherent light scattering by feather nanostructures. Given the complex relationship between feather nanostructures and the colors they produce, intermediate coloration does not necessarily imply intermediate nanostructures. Here, we characterize nanostructural, ecological, and genetic inputs in a distinctive Heliodoxa hummingbird from the foothills of eastern Peru. Genetically, this individual is closely allied with Heliodoxa branickii and H. gularis, but it is not identical to either when nuclear data are assessed. Elevated interspecific heterozygosity further suggests it is a hybrid backcross to H. branickii. Electron microscopy and spectrophotometry of this unique individual reveal key nanostructural differences underlying its distinct gorget color, confirmed by optical modeling. Phylogenetic comparative analysis suggests that the observed gorget coloration divergence from both parentals to this individual would take 6.6–10 My to evolve at the current rate within a single hummingbird lineage. These results emphasize the mosaic nature of hybridization and suggest that hybridization may contribute to the structural color diversity found across hummingbirds.

FIGURE 4 in Biogeography and taxonomy of racket-tail hummingbirds (Aves: Trochilidae: Ocreatus): evidence for species delimitation from morphology and display behavior
FIGURE 4. Summed scoring for plumage (for characters included, see Table 3), biometrics (see Table 4), and display behavior (see Fig. 3) in pairs of Ocreatus; line indicates critical threshold value (7) for species delimitation according to Tobias et al. (2010). Abbreviations: mel = melanantherus, per = peruanus, add = addae, ann = annae.
FIGURE 3 in Biogeography and taxonomy of racket-tail hummingbirds (Aves: Trochilidae: Ocreatus): evidence for species delimitation from morphology and display behavior
FIGURE 3. Aerial displays of Ocreatus males, based on notes from field and laboratory observations by K.-L. Schuchmann (KLS) and C. Cordier (CC) (cf. Appendix 2; after Schuchmann 1987). A—addae (N> 15, April 1984–1992; Bolivia, Cochabamba, eastern slope, cloud forest, 2000 m a.s.l., CC; laboratory observations, Bonn, Germany, KLS): simple, repeated horizontal arc-flight of male in front of/above female without vocalizations, in annae with additional jerky sideward movements (not shown). B—peruanus (south of Quito, Ecuador, KLS): male with dive-in maneuvers with exposed leg puffs and vertically raised rectrices (in addition to A) without vocalizations. C—underwoodii (Mares, Valle del Cauca, Colombia, KLS): similar to B but male afterwards lifting back upwards and then rapidly beating the tail feathers down, producing a prominent, whip-like mechanical sound, which is responded to by female uttering high-pitched uttering calls. For detailed explanation see text. Rating of magnitudes for scoring analysis (cf. Fig. 4) was from 0 (addae vs. annae) to 2 (addae/annae vs. melanantherus). Drawings by S. Rick.

Marks with asterisk indicate localities not referable to pools.

B—from north to south: O. underwoodii melanantherus—pool L (white), pool M (yellow), pool N (orange), pool O (red); O. peruanus—pool P (pale turquoise), pool Q (turquoise), pool R (violet blue), pool S (light purple), pool T (dark purple). C—from north to south: O. annae—pool U (yellow), pool V (orange); O. addae—pool W (turquoise). Note that pools exclude immature specimens; for that and other reasons (see Discussion), possible parapatry of melanantherus and peruanus along the eastern Andean slope in Ecuador is not depicted.
