The people behind the IOC World List have published their latest updates. These have now been incorporated into BUBO Listing. The main changes were the addition of Urrao Antpitta, and the splitting of Horned & Sira Curassows; Hen & Northern Harriers; Common & Cape Verde Buzzards; Banggai, Oberholser's & Sula Fruit Doves; Philippine, Everett's & Negros Scops Owls; Northern & Mexican Barred Owls; Pacific, Salim Ali's, Blyth's and Cook's Swift; Dull-mantled & Magdalena Antbirds; Hair-crested & Tablas Drongos; Grand Comoro & Moheli Bulbuls; Nightingale Reed, Saipan Reed & Pagan Reed Warblers; Streaky-breasted & Bornean Spiderhunters.

Most world listers will find they can increase their list by applying these taxonomic updates! As usual you will be notified if any updates impact you.

The recent round of updates for the Clements checklist, as published by Cornell, have now been incorporated in BUBO Listing. There were plenty of taxonomic updates, including 12 new species and no fewer than 74 different splits. Also major changes to family composition and sequencing.

UPDATE - we'd forgotten to split Water Rail and Brown-cheeked Rail, so you may get prompted again for another taxonomic check.

Following on from our recent updates to the Clements Checklist, we have now updated the IOC World List to the recently released v2.9. Of most interest to listers will be the 15 new species added:

  • Tsingy Wood Rail Canirallus beankaensis
  • Black-banded Fruit Dove Ptilinopus alligator
  • Blue-moustached Bee-eater Merops mentalis
  • Whitely's Toucanet Aulacorhynchus whitelianus
  • Bronze-winged Woodpecker Colaptes aeruginosus
  • Xingu Scale-backed Antbird Willisornis vidua
  • Northern Fiscal Lanius humeralis
  • Mexican Jay Aphelocoma wollweberi
  • Montane Tiny Greenbul Phyllastrephus albigula
  • Sakhalin Grasshopper Warbler Locustella amnicola
  • Sao Tome White-eye Zosterops feae
  • Philippine Magpie-Robin Copsychus mindanensis
  • Orange-tufted Spiderhunter Arachnothera flammifera
  • Pale Spiderhunter Arachnothera dilutior
  • Masked Cardinal Paroaria nigrogenis

As always, BUBO Listing will alert you to any updates you need to make because of this. For details about how to do these, see how taxonomic updates are handled in BUBO Listing.

World listers will be pleased to hear that we have implemented all the recent updates to the Clements Checklist. There were many taxonomic changes, including several splits (especially amongst Asian babblers for example), a few lumps and many changes to the sequence of various passerine families.

We have just launched the IOC World List on BUBO Listing. This has been requested by many BUBO Listers and we feel it is likely to be adopted by most as their preferred world listing authority. We have also included species distribution details for all species to make it easier to understand the taxonomic differences between this and the Clements World List.

If you already have a world list on BUBO Listing based on Clements it is very easy to convert this into an IOC one. Just use Create New List as normal and ensure you use the "Copy from existing list" option, and specify your Clements world list. Where possible we have mapped taxa between IOC and Clements so it is likely that more than 90% of your list copy will be automatic. Where taxonomic treatment differs you will need to add the appropriate IOC taxa manually, using Batch Edit or View/Edit Species under My Lists. We have enhanced the list copying so that those species that cannot be mapped automatically are emailed to you so it is easy to add them to your new IOC world list at your leisure.

Of course if you don't already have a Clements world list then just Create New List as normal and we suggest pouring yourself a drink as you begin the task of entering all your records! Naturally it takes a while for big world lists, but it is a fun job to do, interrupted by pleasant reminiscences of past birding trips worldwide!

We have also compiled a basic summary of the taxonomic differences between the Clements and IOC world lists.
