(2012) is an interesting case. We believe that the authors of the paper describing <i style='mso-bidi-font-style:normal'>Cinclodes espinhacensis</i> have missed the opportunity of making a more useful comparison of vocalizations in the genus and have based their conclusion mostly on our previous lack of knowledge to justify their species instead of putting forward a better frame to understand what a species should be in <i>Cinclodes</i>. There is no thorough comparative study of other species vocalizations or morphology and no evaluation of behavioral responses to playback, and thus no possibility of evaluating whether the differences described should be interpreted as indicating the existence of a new species or of a new subspecies. Weighing up the evidence mentally in comparison to <i style='mso-bidi-font-style:normal'>Cinclodes</i> with which we are familiar (including<i style='mso-bidi-font-style:normal'> pabsti</i>), does not reveal any meaningful biological difference between <i style='mso-bidi-font-style:normal'>espinhacensis</i> and <i style='mso-bidi-font-style: normal'>pabsti</i> to justify their treatment as different species. More objective reasons to support this view are summarized below.</p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'><o:p>&nbsp;</o:p></b></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> Vocalizations</b>: even though Freitas et al. (2012) have found differences in some acoustic parameters, these are highly variable, and there is no mention on whether the cuts were unsolicited or in response to playback, which may influence parameters such as pitch and number of notes per vocalization (let alone differences due to different recording gear and recording quality), several acoustic parameters also show no difference (9 out of 17 parameters show no difference, while 8 out of 17 do; how should we interpret this?), the shape of notes in the songs is identical (the call is also extremely similar in every respect with 3 out of 6 parameters showing no differences; without a clear  yardstick we cannot evaluate just how conservative songs are in<i style='mso-bidi-font-style:normal'> Cinclodes</i>), and finally there is a whole lot of pseudoreplication in their measurements as it is not clear how many calls and songs from each individual they've measured (i.e., individual consistency and species level differences are conflated).</p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> <o:p></o:p></b></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'>Morphology</b>: there is no diagnosable morphometric difference except for tarsus (with a large p, though...) and weight (which is awkward, given that morphometrics usually correlated with weight such as wing size are identical; we are in the presence of two birds with very similar shapes which have dramatic weight differences, perhaps an artifact of weighing birds in different seasons and/or with different tools?)</p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'><o:p>&nbsp;</o:p></b></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> Comparison to <i style='mso-bidi-font-style:normal'>Upucerthia</i></b>: given the lack of comparative data within <i style='mso-bidi-font-style:normal'>Cinclodes</i>, looking at its sister genus <i style='mso-bidi-font-style:normal'>Upucerthia</i> is warranted. The authors didn't mention the existence of ecogeographic variation in <i>Upucerthia </i><span style='mso-bidi-font-style:italic'>(e.g., <i>U. dumetaria</i> and <i>U. jelskii</i>), which</span> may easily explain the difference in coloration between <i style='mso-bidi-font-style:normal'>espinhacensis</i>/<i style='mso-bidi-font-style:normal'>pabsti</i> without necessarily meaning that a different species is involved (indeed, all undisputedly valid species in <i style='mso-bidi-font-style:normal'>Cinclodes</i> [and<i style='mso-bidi-font-style: normal'> Upucerthia</i>] differ in pattern and coloration, not just coloration). Tail pattern is particularly important in <i style='mso-bidi-font-style: normal'>Cinclodes</i> yet <i style='mso-bidi-font-style:normal'>pabsti</i> and <i style='mso-bidi-font-style:normal'>espinhacensis</i> show identical tail patterns. The level of differentiation found between <i style='mso-bidi-font-style: normal'>espinhacensis</i> and <i style='mso-bidi-font-style:normal'>pabsti</i> seems equivalent to that between <i style='mso-bidi-font-style:normal'>Upucerthia jelskii</i> and <i style='mso-bidi-font-style:normal'>U. validirostris</i> two  species that answer readily to playback of each other (whose vocalizations are so variable that they defy any meaningful quantitative characterization despite being structurally undistinguishable as is the case of note shape [and pattern?] in <i style='mso-bidi-font-style:normal'>espinhacensis</i>/<i style='mso-bidi-font-style:normal'>pabsti</i>) and which should be considered as part of a single geographically variable species (Areta and Pearman <i style='mso-bidi-font-style:normal'>in press</i>). If the darker saturation of dorsal plumage in <i style='mso-bidi-font-style:normal'>espinhacensis</i> is the only difference between it and <i style='mso-bidi-font-style:normal'>pabsti</i>, then similar distinctions at subspecies rank or indeed at color morph level can be found in numerous furnariid species (Remsen 2003).</p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'><o:p>&nbsp;</o:p></b></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> Genetic differences</b>: the meager genetic differentiation, with values falling between those of the conflictive cases <i style='mso-bidi-font-style:normal'>oustaleti-olrogi</i> and <i style='mso-bidi-font-style:normal'>nigrofumosus-taczanowskii</i>, adds little to answer the question of the species-level of <i style='mso-bidi-font-style: normal'>espinhacensis</i> but if anything, it should raise suspicion.</p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'><o:p>&nbsp;</o:p></b></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> Geographical gap</b>: finally, we would like to stress that the gap between <i style='mso-bidi-font-style: normal'>espinhacensis</i> and <i style='mso-bidi-font-style:normal'>pabsti</i> should not be used as a tool for species-level assignment. A large gap (for the poor flying <i style='mso-bidi-font-style:normal'>Scytalopus</i>) of 450 km is known to exist (or was known to exist) between records of <i style='mso-bidi-font-style: normal'>S. iraiensis </i>in Paran· and Minas Gerais, which may well be a sampling artifact (Vasconcelos et al. 2008). How much of the gap between <i style='mso-bidi-font-style:normal'>espinhacensis</i> and <i style='mso-bidi-font-style: normal'>pabsti</i> is an artifact? Let us also consider that species such as <i style='mso-bidi-font-style:normal'>Cinclodes fuscus</i> may easily fly 3000 km from Patagonia to Buenos Aires and another 3000 km back every season during their migration (and perhaps much more, when reaching south-east Brazil). To be clear: the gap between <i style='mso-bidi-font-style:normal'>espinhacensis</i> and <i style='mso-bidi-font-style:normal'>pabsti</i> is within flight distance of at least one migrant <i style='mso-bidi-font-style:normal'>Cinclodes</i>, and all inland <i style='mso-bidi-font-style:normal'>Cinclodes</i> have powerful flights.</p> <p class=MsoNormal><o:p>&nbsp;</o:p></p> <p class=MsoNormal> In sum, we do not see evidence for considering the EspinhaÁo birds as a different (biological) species from southern birds, and hope these arguments will generate an interesting discussion for SACC members.</p> <p class=MsoNormal><o:p>&nbsp;</o:p></p> <p class=MsoNormal><b style='mso-bidi-font-weight:normal'> References<o:p></o:p></b></p> <p class=MsoNormal style='margin-left:.25in;text-indent:-.25in'>Areta, J.I. and M.

No attempt in the paper is made to use statistical tests for diagnosability.&nbsp; Following the nomenclature for stats in my recent series of papers, the&nbsp;authors of this new taxon&nbsp;therefore looked only at &quot;Level 1&quot; (statistical significance of differences between means using t; the weakest form of differentiation) and &quot;Level 4&quot; (diagnosability based on recorded values; which is the form of differentiation most subject to biases related to sample size).&nbsp; The Isler et al. 97.5% test of diagnosability was not applied, nor were any tests of 50% or 75% diagnosability.&nbsp; Out of the continuous vocal and biometric variables studied, only body mass appears to have met the &quot;Level 4&quot; test.&nbsp; However, here, the means are less than four average standard deviations apart, so would not meet statistical tests of diagnosability (Level 5), even before controlling for sample size.&nbsp; I do not know these birds and do not want these comments to detract in any way from appreciation of the authors' efforts in discovering and publishing many interesting details of this previously undescribed new taxon.&nbsp; Other data, notably molecular and plumage data, will be relevant to the question of species rank too.&quot;</span><span style='font-family:Cambria; mso-ascii-theme-font:minor-latin;mso-hansi-theme-font:minor-latin'><o:p></o:p></span></p> <p class=MsoNormal><span style='font-family:Cambria;mso-ascii-theme-font:minor-latin; mso-hansi-theme-font:minor-latin'><o:p>&nbsp;</o:p></span></p> <p class=MsoNormal style='mso-pagination:none;mso-layout-grid-align:none; text-autospace:none'><u><span style='font-family:Arial;mso-bidi-font-family: "Times New Roman"'>Additional comments from Zimmer</span></u><span style='font-family:Arial;mso-bidi-font-family:"Times New Roman"'>:  </span><span style='font-family:Helvetica;mso-bidi-font-family:Helvetica'>One of the highlights of the tour was our couple of days in the EspinhaÁo range, where we were able to locate a couple of pairs of the recently described <i>Cinclodes espinhacensis</i>. &nbsp;I had voted on the relevant proposal (#548) to the SACC just prior to the trip, rendering my vote based solely on available information as presented in Freitas et al.

</span>Each time I attempted playback of the song of <i>pabsti</i> (using pre-recorded songs of 4 different individual <i>pabsti</i>&nbsp;from Rio Grande do Sul), the pair of <i>espinhacensis</i>&nbsp;came roaring back in, singing and displaying wildly.<o:p></o:p></span></p> <p class=MsoNormal style='mso-pagination:none;mso-layout-grid-align:none;

</span>Once again, the reaction was immediate, with the bird we were watching flying straight at us and landing on the ground nearby and calling (single-note calls) over and over in apparent distress.<span style="mso-spacerun:yes">&nbsp;

</span>On the other hand, a complete absence of response to playback is usually more informative, especially if the recipient of the playback responds to its own voice without responding to the other taxon.<span style="mso-spacerun:yes">&nbsp; </span>And, I do think that the voices of the various cinclodes are largely similar enough that a positive response from one species to playback of another is not necessarily a deal-breaker.<span style="mso-spacerun:yes">&nbsp; </span>However, in the current case, the response from 2 pairs of <i>espinhacensis</i>&nbsp;to both single-note calls and loudsongs of <i>pabsti</i>&nbsp;was immediate, dramatic, and vigorous, and accompanied by the same sorts of wing-flapping displays that are used by other cinclodes in defending their territories against conspecifics. &nbsp;I can think of plenty of closely related species-pairs with parapatric/allopatric distributions in which the loudsongs are nearly identical but the calls are very different (e.g. some pairs in the <i>Hypocnemis cantator</i>&nbsp;complex), or, where the calls are nearly identical but the loudsongs are very different (e.g. <i>Schistocichla</i> antbirds), but seldom are both the calls and the songs as well as the associated territorial displays identical.<o:p></o:p></span></p> <p class=MsoNormal style='mso-pagination:none;mso-layout-grid-align:none;

</span>While that may be the case for the bulk of the population, the pairs of <i>espinhacensis</i> that we encountered were at the lower elevational limit, and were frequenting highly human-modified pasture and margins of seasonal ponds, all subject to heavy grazing by cattle and horses -- in other words, the same kinds of habitats where one finds <i>pabsti</i> in Rio Grande do Sul.<o:p></o:p></span></p> <p class=MsoNormal style='mso-pagination:none;mso-layout-grid-align:none;

This is another borderline case as the one in Proposal 545. Species level definition in <i style='mso-bidi-font-style:normal'>Cinclodes</i> is not clearly associated to particular levels of divergence either in morphological or vocal characters. Similarly, level of molecular divergence among sister  species is characterized for a wide range of values, a pattern that might be the result of different historical and/or ecological processes associated with their divergence or problems with current taxonomy in the genus. In the particular case of this proposal, <i>espinhacensis</i> differs from <i>pabsti</i><span style='mso-bidi-font-style:italic'> in plumage coloration and size but in general are very similar birds with similar vocalizations. Moreover, after reading the article by Freitas et al. (2012), vocal analyses might suffer from lack of independence and lack of diagnosability tests, as others have indicated before. Kevin s data on playback further incline the balance toward recognition of two subspecies instead of two valid species under the BSC.
