August is upon us, and whether we like it or not, it's time for the next update to the ebird/Clements taxonomy. As a birder I personally wouldn't mind if the taxonomists took a break, giving us a chance to adapt to the changes that seem to flood us mercilessly during these years. In vain, however, I know, as long as there are still genetic 'mysteries' unsolved. So while looking forward to the day all birds have been genetically examined and catalogued, I'll do what I can to keep up with the flow of knowledge, recognizing that life becomes easier if we all speak the same language.
All the changes relevant to Mexico can be seen in the article linked-to here above, but the most important ones are as follows:
Two new species are added to the official list of Mexico, since both Mallard and White-collared Seedeater are being split into two new species, respectively, and all the four species are present in Mexico: Mallard, Mexican Duck, Morelet's Seedeater and Cinnamon-rumped Seedeater. Time to study the differences between females of the latter two.
And Vermiculated Screech-Owl, Paltry Tyrannulet and Passirini's Tanager all become historical names since the two first gain new names through splits and the latter through a lump: Middle American Screech-Owl, Guatemalan Tyrannulet and Scarlet-rumped Tanager.
The thorough re-positioning of the orders of the non-passerines this year will probably cause some confusion at first among users. Now for example, Pigeons and Doves and Shorebirds and Relatives are to be found before the raptors, and Cuckoo and Nightjars before the Shorebirds. This is of course very must out of sync with any given field guide, and one can only hope that the changes made now are consensus born, giving new field guide editions [and the rest of us] a chance to keep up with the development.
