This week I got my hands (thanks to Loreta Rosselli) an article describing a new species of parrot of Colombia. 20 years ago, one of the authors spoke to a poultry dealer Melgar (Tolima), who mentioned the existence of a yellow-necked parakeet. In January 2010, doing fieldwork on the Internet, the authors found a photo which apparently confirmed that indeed there was a sort of yellow-necked parakeet, which had gone unnoticed by scientists.

The first error is so serious, is that the article did not designate a type specimen as required by International Code of Zoological Nomenclature , so technically the description of F. flavicollis is invalid. The second error is the background: these birds do not represent a new species! They are simply Cascabelito ( Forpus conspicillatus) to which I have painted or faded plumage to make them look like something different, a common practice among wildlife traffickers. The Cascabelito is one of the most common species of parrots in Colombia, is abundant in the region from which the photo and also, even as the authors acknowledge, in the photo is clear that besides the individual is the yellow-necked but one which undoubtedly is a Cascabelito that has not been adulterated plumage.
ever heard the story that the great Mono Hernández on one occasion did the same, that she thought she found a new species of parrot plumage typical Colombian. However, if I remember correctly, the monkey was careful enough to wait until the birds molt and regain their normal plumage, so the supposed new species was never described (if anyone knows the story well, any comments are welcome) . What I know is that the book parrot of Colombia, and José Vicente Rodríguez Mono, they mention that alter the plumage of parrots is a widespread activity among the dealers of these animals. Perhaps the authors of the description of " flavicollis F. " did not have access to this book ...
