Abstract: ABSTRACT. The genus Sporophila (Cabanis, 1844) unites about 30 species of small seedeaters that predominantly inhabit open or semi-open areas in the Neotropical region. The taxonomy of this group is based on morphological studies from collected male specimens. The dynamic spatial and temporal variation in the male plumage and lack of knowledge of their vocalizations make it difficult to properly diagnose some species even today, so these two aspects account for the existing taxonomic dilemmas involving Sporoph… Show more

“…The notes of the introduction, main song and calls of all other species of capuchinos are clearly different, both observed in our comparison, as with the direct comparison with the characteristic spectrograms for capuchinos that other authors have published (see Areta 2008, Repenning et al 2010, Areta et al 2011, Areta and Repenning 2011a, 2011b, Campagna et al 2011). Note that in the introductions of other species (Figure 3I-VII), all notes have a frequency distribution almost vertical and descending in all cases, whereas in S. iberaensis these notes are ascending or stable, but mostly appears in the form of main note with shape of “Eiffel Tower” with a significant frequency range both ascending and descending symmetrically.…”

“…We did not find that any other species of capuchinos had the note shaped as an “Eiffel Tower” that is consistently present in the introductions of S. iberaensis . We consider this a diagnostic note of the species both considering our study of spectrograms of six species of capuchinos, and the spectrograms provided in the results of studies by Areta (2008), Areta et al (2011), Areta and Repenning (2011a, 2011b) and Repenning et al (2010).…”

“…The taxonomy of the southern capuchinos is based on male plumage coloration and song, and to a lesser extent on geographic distribution and habitat use (Meyer de Schauensee , Ridgely and Tudor , Rising et al ). Recent detailed analyses of these traits have led to the discovery of alternative color morphs within some species (Repenning et al , Areta and Repenning , Areta et al ), the merger of previously recognized taxa (Areta ), and helped identify the sister species to the core southern capuchino radiation (Machado and Silveira , , Campagna et al ). The southern capuchino species that are currently recognized show statistically significant differences in their songs and plumage attributes, which are maintained in sympatry (Benites et al , Campagna et al ).…”

“…Despite the limitation of only being able to detect putative hybrids in a single sex and age class, a number of unusual coloration patterns have been described in four capuchino seedeater species: Sporophila hypoxantha has an alternative coloration morph known as uruguaya [ 20 ], S . melanogaster presents the xumanxu morph [ 21 ], S . ruficollis the caraguata morph [ 22 ] and S .…”
