Table 3 in Integrative taxonomy reveals hidden diversity in the Catharus fuscater (Passeriformes: Turdidae) complex in Central and South America

Table 3. Adult plumage colour variation in the C. [fuscater] complex based on specimens in the ANSP, DMNH, FMNH, and LSUMZ. Numbers taken from Smithe (1975) denote colours on the crown, back, undertail coverts (tl-covs), flanks, breast, and throat. ‘Chin’ is scored with two levels (0,1) referring to the absence or presence, respectively, of an unbroken (although sometimes faint) line of darker feathers connecting the malar regions across the chin. Specimens from southern Ecuador and north-western Peru (C. [f.] caniceps) were scored separately from north-western Ecuador (C. [f.] berlepschi), despite showing low genetic divergence, to illustrate plumage colour differences. Specimens from eastern Panama (C. [f.] mirabilis, Undescribed 1) were scored using non-fresh (faded) specimens (see text). Color scores from a ‘brown type’ unsexed specimen of C. [f.] fuscater, the only study skin of that taxon available for the formal analysis, are included below as ‘female’. SexNTaxonCrownBacktl-covsFlanksBreastThroatChinM5C.

[fuscater]复合群成体羽色变异。 本研究依据Smithe（1975）的色号标准，对头顶、背部、尾下覆羽（undertail coverts，简称tl-covs）、胁部、胸部及喉部的羽色进行标识。“颏部”评分分为两个等级（0、1），分别对应横贯颏部、连接两侧颊区的不间断深色羽带（有时色泽较淡）的有无。 尽管厄瓜多尔南部与秘鲁西北部的标本（C. [f.] caniceps）与厄瓜多尔西北部的标本（C. [f.] berlepschi）之间遗传分化程度较低，但为清晰展示羽色差异，本研究仍将二者分开评分。 来自巴拿马东部的标本（C. [f.] mirabilis，未描述类群1）采用非新鲜（褪色）标本进行评分，详细说明参见正文。 本次正式分析仅能获取C. [f.] fuscater的唯一一件剥制研究标本——一件未鉴定性别的“褐色型”标本，其羽色评分被纳入下文并标注为“雌性”。 以下为评分表格： 性别|标本数|分类群|头顶|背部|尾下覆羽|胁部|胸部|喉部|颏部 M|5|C.
