OK, now that we're on this subject, I've been wondering...

I gather that there is a list of vernacular, standard, English-language
names for all(?most) bird species of the world. Or, at least, for those
in the western hemisphere. Right?

These names make it easier for some people (esp. English-speaking
people) to discuss birds without resorting to using the Latin
binomials. That's good, I guess.

What I want to know is whether a "standard" list of bird names exists
in other languages, e.g., Spanish (a Spanish-speaker's "AOU" list), for
the birds of the hemisphere/world? If not, why not? If so, how about a
citation?

E.g., I have a difficult time discussing birding in Colombia with one
of my brothers-in-law, who is Colombian and is a rank novice birder,
because most of the birds he might see/discuss have no standard common
name in Spanish (as far as I know), so he is forced to use the Latin
binomials. That's ok with me, but not with him, and if we look at
tweeters discussions, use of common names is good.

There are lots of birds with (multiple*) common names in (Colombian)
Spanish, especially for birds found about the cities and towns. But
they represent a very small percentage of all Colombian bird species.

* Historical isolation due to rugged geography and regional cultural
differences has led to a proliferation of common names in Colombia.
Different species with the same name; same species with different names
(even within one small region due to immigration of people to the
region from many other places in Col)., etc.

If we want people to be concerned about their flora/fauna, they have to
be able to name it and talk about it. Common English names, and Latin
binomials, are not useful for the non-English-speaking concerned citizen.
