Taxonomy changes in birds

Today I got the latest update of the recently published The Clements Checklist of Birds of the World, 6th Edition by the late James F. Clements. I am not as serious bird 'hunter' for my list as my other friends but love to see new things and the birds are in the leading position. In 2006 I spent a nice holiday in Cuba with my wife and saw the local race of Common Black-Hawk which is now considered as a separate species named Cuban Hawk-Eagle Buteogallus gundlachii. If you are a list keeper it is very useful to record not only the species but the subspecies as well. Taxonomy changes can result surprise while you are sitting in your chair at home. It is sad to see some of the species recently confirmed/believed to be extict such as Guam Flycatcher Myiagra freycineti (Guam, S Mariana Islands), Kauai Oo Moho braccatus (Kauai, Hawaiian Island) and Bishop’s Oo Moho bishopi (Maui, Hawaiian Island). It is a little bit strange for my eyes to read that due to the recent phylogenetic analyses a close sister-group relationship identified between flamingos Phoenicopteriformes and grebes Podicipediformes. This is now recommended by the British Ornithologists' Union (published in Ibis) to name this group as Mirandornithes and place them between Ciconiiformes and Falconiformes, with the flamingos listed before the grebes. There is again a huge change in the Gull family indicating that our knowledge is not yet fully complete regarding this group of birds. Studies provided some new result in the relationship of different species that's why BOU recommends a new sequence list for the birds ever recorded in Europe: Ivory Gull Pagophila eburnea Sabine’s Gull Xema sabini Black-legged Kittiwake Rissa tridactyla Slender-billed Gull Chroicocephalus genei Bonaparte’s Gull Chroicocephalus philadelphia Black-headed Gull Chroicocephalus ridibundus Little Gull Hydrocoloeus minutus Ross’s Gull Rhodostethia rosea Laughing Gull Larus atricilla Franklin’s Gull Larus pipixcan Mediterranean Gull Larus melanocephalus Audouin’s Gull Larus audouinii Pallas’s Gull Larus ichthyaetus Mew Gull Larus canus Ring-billed Gull Larus delawarensis Lesser Black-backed Gull Larus fuscus Herring Gull Larus argentatus Yellow-legged Gull Larus michahellis Caspian Gull Larus cachinnans American Herring Gull Larus smithsonianus Iceland Gull Larus glaucoides Glaucous Gull Larus hyperboreus Great Black-backed Gull Larus marinus The member of former Larus genus decreased drastically as a result of grouping the species showing strong relationship with each other. Naming e.g the new genus Chroicocephalus with three species in Europe (Slender-billed Gull, Bonaparte’s Gull and Black-headed Gull) is among the main changes. So today I won a species but maybe next time I will loose one due to lumping. You never know but all in all this is a game. :) I have seen 2001 species so far... ______ Please don't hesitate to share your thoughts, feelings and comments on my blog or its content.
