Proposal (99) to South American Classification Committee
Change English name of Ramphocelus melanogaster
Effect on South American CL: This proposal would change the English name of
a species on our list from a "Meyer de Schauensee" name
("Black-bellied Tanager") to an "Isler" name
("Huallaga Tanager").
Background: Meyer de Schauensee (1966, 1970) used the name
"Black-bellied Tanager" for Ramphocelus melanogaster, and this
was followed by Parker et al. (1982) and presumably other literature, until
Isler & Isler (1987) changed this to "Huallaga Tanager " in
reference to its small range, the Huallaga River valley of Peru. This was
followed by Ridgely & Tudor (1989), who noted:
"As R. melanogaster is no more
"Black-bellied' than is R. dimidiatus (and is much less
so than many races of R. carbo), we find that formerly used name to
be decidedly misleading. As its range is limited to the Huallaga River valley,
that name provides a good modifier."
This
was followed by Sibley & Monroe (1990) and Clements and Shany (2001), but
not Dickinson (2003).
Analysis: I think Bob's description (above) of "Black-bellied"
as "decidedly misleading" is somewhat over-the-top. Although R.
melanogaster is indeed no more "black-bellied" than R. dimidiatus,
the name emphasizes a striking difference between it and parapatric R. carbo;
whereas the parapatric form of the latter has a blackish belly the blends into
the dull reddish breast, R. dimidiatus has a sharply demarcated pure
black belly that is highlighted by the brilliant red breast, sides, and flanks
--its "gaster" is indeed very "melano" -- it was given that
scientific name for a good reason. Worries about confusion between R.
dimidiatus and R. melanogaster are, for field ornithologists, a
geographical impossibility.
Recommendation: I tentatively vote "NO" on this proposal because
my basic philosophy is "just live with" old, bad names for sake of
stability unless highly misleading. On the other hand, I like geographic names,
and "the" book for the Thraupidae uses "Huallaga," as does
the current field guide for Peru. What will convince me to vote YES is the word
from Tom that the new Peru book will use "Huallaga."

===========================
Comments from Robbins: "YES. This is an improvement as it
accurately conveys its restricted distribution."
Comments from Zimmer: "YES. I don't like to tinker with
established names too much, but when we can substitute a good geographic name
for a marginal plumage-based descriptive name for what is a highly localized
species, then I'm all for it. The disruption in continuity would seem to be
more than offset by a name that is much more informative, and memorable (as
opposed to another descriptive name)."
Comments from Schulenberg: "NO. To begin with, I don't see any need
to change the name. There has been no taxonomic revision requiring names for
newly recognized (BSC) species level taxa, so ... why change an existing name
rather than maintain the stability of an existing name?
ÒSecondarily,
the name "Huallaga Tanager" does not work well for me. Ramphocelus
melanogaster is found only in the Rio Huallaga drainage of Peru - that is
true. However, it is not found on the lower Huallaga (where Ramphocelus
carbo occurs). It is the dominant Ramphocelus in the Rio Mayo
valley, a tributary of the Huallaga; and it may be the only Ramphocelus in
the uppermost, tropical portions of the Huallaga near Tingo Maria. Along the
Huallaga itself, upstream from the mouth of the Mayo but below Tingo Maria, the
picture is more clouded. This is a poorly known area, but it appears that at
the junction of the Huallaga and the Mayo carbo is the dominant Ramphocelus.
And carbo, or carbo x melanogaster hybrids, reportedly
have been collected at several sites upstream from there (i.e., in the
direction of Tingo).
ÒSo,
melanogaster is confined to the Huallaga valley. But it does not
occupy the entire Huallaga drainage, and seems to overlap, at least in part,
with the more widespread carbo.
ÒMaybe
I'm too close to all this ("thinking about it too much"). But the
geographic situation is, to me, unexpectedly complicated, and so I am reluctant
to endorse this name change. Of course, as already mentioned, I would have
needed a very very good reason/strong argument to change an existing name in
the first place.Ó
Comments from Stiles: "NO, in the name of consistency, although
personally I like "Huallaga" (to me it is irrelevant whether there
are one or ten more congeners in the Huallaga valley if this is the only one
restricted to it). However, "black-bellied" is not wrong, just non-diagnostic,
and is a mnemonic for the scientific name."
Comments from Nores: "NO, aunque el
vientre negro no es exclusivo de esta especie, no es para m’ un
"misleading name". Con este criterio habr’a que cambiar el nombre a
muchas otras especies que no tienen un color exclusivo. Por ejemplo: Masked
Yellowthroat (Geothlypis aequinoctialis), el cual tiene la m‡scara menor
que Geothlypis semiflava, e igual que Geothlypis trichas."
Comments from Jaramillo: "NO. This was a difficult one. I don't want to
change the name to maintain stability, but at the same time since so many works
have adopted Huallaga Tanager, maintaining our status quo will be seen as a
name change by many users of English Names. In other words, this committee
should have been around 20 years ago, before every bird book author started
changing names! I don't think Black-bellied is wrong, just not all that
creative, and since Tom has problems with Huallaga from a geographic
perspective it all adds up to a no vote for me. Stay with Black-bellied
Tanager."
