Underestimated Neotropical diversity: Integrative taxonomy reveals two unrelated look-alike species in a suboscine bird (Pachyramphus albogriseus)
<p>We applied an integrative taxonomic framework to evaluate the systematics of the Neotropical Black-and-white Becard, <em>Pachyramphus albogriseus</em> Sclater 1857. Combining phylogenomic (ultraconserved elements), morphological, and vocalization data, we confirmed that this species is polyphyletic; some individuals form a clade sister to <em>P. polychopterus</em> and should be afforded species rank as <em>P. salvini</em> Richmond 1899 (Slender-billed Becard), whereas the remaining subspecies of <em>P. albogriseus</em> (Broad-banded Becard) are sister to <em>P. major</em>. We found that <em>P. salvini</em> differs from <em>P. albogriseus</em> in song, color of the lores, wing-bar width, body size, and bill width. Whereas <em>P. albogriseus</em> occurs in montane forest in Costa Rica and Panama (ssp. <em>ornatus</em>) and along the eastern slope of the Andes from to N Venezuela to S Peru (ssp. <em>albogriseus</em>), <em>P. salvini</em> is found in the lowlands from Pacific Colombia south to NW Peru and in the Río Marañón drainage. The latter also occurs, possibly only seasonally, along the eastern slope of the Andes, where the two species' ranges approach closely. We treat <em>P. a. guayaquilensis</em> Zimmer 1936 as a junior synonym of <em>P. salvini</em> Richmond 1899, and <em>P. a. coronatus</em> Phelps and Phelps 1953 as a junior synonym of <em>P. a. albogriseus</em> Sclater 1857. This study provides a striking example of a major problem for comparative biology: underestimated and mischaracterized diversity. We argue that there are likely many more cases like this awaiting discovery.</p>

Ecological and evolutionary drivers of geographic variation in songs of a Neotropical suboscine bird: The Drab-breasted Bamboo Tyrant (Hemitriccus diops, Rhynchocyclidae)
<p>Understanding the evolutionary and ecological mechanisms that shape the spatial divergence of signals involved in reproductive isolation is a central goal in studies of speciation. For birds with innate songs, such as the suboscine passerine birds, the integration and comparison of both genetic and ecological factors in explaining song variation at the microevolutionary scale is rare. Here we evaluated the evolutionary and ecological processes underlying the variation in the songs of the Atlantic Forest endemic Drab-breasted Bamboo Tyrant (<i>Hemitriccus diops</i>), testing the effects of both stochastic and adaptive processes, namely the Stochastic and Adaptation Acoustic Hypotheses, respectively. We combined vocal, genetic and ecological (climate and forest cover) data across the species' range. To this end, we analyzed 89 samples of long and short songs. We performed analyses on raw and synthetic data song variables with linear mixed models and multivariate statistics. Our results show that both song types differ in spectral features between the two extant phylogeographic lineages of this species, but such vocal divergence is weak and subtle in both song types. Overall, there is a positive relationship of acoustic distances with the amount of forest cover in long songs. Our results suggest that there is cryptic geographical variation in both song types and that this variation is associated with low levels of genetic divergence in both songs and with ecological factors in long songs.</p>

FIGURE 4. simplified chronogram from the BEAST analyses, illustrating the crown age and number of extant species for most clades recognized as family level taxa in our proposed classification. Unresolved nodes are collapsed and species richness of each terminal clade is illustrated by its height. Clades are coloured in accordance with their species number: black: ≤19 species; medium grey: 31–54 species, light grey:>75 species. Blue bars show the 95% confidence interval of the age estimates. The curve at the bottom of the chronogram is a simplified version of the δO18 curve of Zachos et al. (2001), serving as a proxy for global temperature.
