Peacocks exterminated, reference removed

edit

I've removed or altered unreferenced claims in the Research section. In the process,

I've deleted one reference from the article:

<ref>{{Cite web |url=http://www.uba.ar/comunicacion/p_electronicas/uu/anteriores/septiembre04/notas/02a.php |title=Archived copy |access-date=2008-02-21 |archive-url=https://web.archive.org/web/20080218013321/http://www.uba.ar/comunicacion/p_electronicas/uu/anteriores/septiembre04/notas/02a.php |archive-date=2008-02-18 |url-status=dead |df= }}</ref>

This reference establishes the existence of the mentioned 10th International Clinic Congress, but makes absolutely no mention of Tangolates, or the specific claims that were framed to be supported by the reference. This is misleading, so I removed it.
