Proposal (101) to South American Classification Committee
Change English name of Tangara viridicollis
Effect on South American CL: This proposal would change the
English name of a species on our list from a "Meyer de Schauensee"
name ("Silvery Tanager") to an "Isler" name
("Silver-backed Tanager").
Background: Meyer de Schauensee (1966, 1970) used the
name "Silvery Tanager" for Tangara viridicollis, and this was
followed by Parker et al. (1982) and presumably other literature, until Isler
& Isler (1987) changed this to "Silver-backed Tanager. " This was
followed by Ridgely & Tudor (1989), who noted:
"As this bird is not predominately silvery, we have
opted to slightly modify its English name to 'Silver-backed'; dorsal color also
represents the simplest way to separate T. viridicollis from
the closely related T. argyrofenges."
This was followed by Sibley & Monroe (1990), Clements and
Shany (2001), and Hennessey (2003), but not Fjeldså & Krabbe (1990) or
Dickinson (2003).
Analysis: "Silvery-backed" might be a slightly better name, but
not dramatically so. In contrast to the statement above, throat color is just
as simple a way to tell T. viridicollis from T. argyrofenges (which
will be brought up in companion proposal), and the silver of T. viridicollis
is not restricted to the back but also the conspicuously contrasting sides and
flanks.
Recommendation: I tentatively vote NO on this proposal. In
this case, I do not think the loss of an historical name is worth the slight,
at best, improvement. On the other hand, the change is not large, and if Tom is
going to use "Silver-backed" in the new Peru book, I'll change my
vote.

Comments from Robbins: "YES. I find that this is
enough of an improvement to merit the change."
Comments from Zimmer: "YES. I really think this
name is much more appropriate in conjuring up what the bird looks like, and it
has been used in a number of references."
Comments from Stiles: "NO - the old name is not
wrong, just nondiagnostic."
Comments from Nores: "Si. Yo no estoy de acuerdo en denominar a una especie como si fuera de un
color uniforme, cuando sólo tiene de ese color una parte del cuerpo. Con el
criterio anterior también se podría haber llamado a esta especie "Black Tanager"
porque tiene negro la parte ventral y la corona."
Comments from Jaramillo: "YES. I do find Silvery somewhat misleading, and
Silver-backed does conjure up a better image of what this bird looks like. I am
also going for Straw-backed on the next proposal and do like the parallel
nature of these names."
