As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

BOU to adopt IOC World Bird List

The British Ornithologists' Union (BOU) has announced that it is to adopt the International Ornithological Congress (IOC) World Bird List for all its ornithological needs, including the British list, from 1 January 2018.
This follows a detailed review by the BOU's Records Committee (BOURC), which involved inviting the four main global avian taxonomic authorities (eBird/Clements, HBW/BirdLife, Howard & Moore and IOC World Bird List) to each submit a proposal that could be assessed against agreed BOURC criteria and related questions.

Initially, the BOU Council appointed a delegation which discussed the merits of each proposal to help arrive at an informed view on behalf of Council. This delegation reviewed the proposals but did not consider there was any strong reason to make a recommendation for any of the candidate taxonomies ahead of a full meeting of BOURC.

BOURC subsequently met on 10 December 2016 and invited members of the Council delegation to attend, two of whom did so. The Council delegates engaged in discussions but had no vote in the process. It was expected a recommendation to BOU Council would be made as a result of the meeting. All members of BOURC, bar one, were present.

Before discussing the taxonomic proposals in detail, the Committee considered two issues raised by those present. First, the need for and benefits of a unified global taxonomy were agreed upon. Second, it was agreed that the EU's current use of the HBW/BirdLife taxonomy would not be a material factor influencing the Committee's discussions.

The Howard & Moore proposal was discussed first as this was the only proposal for a taxonomic system which was not currently available online, and the Committee felt that accessibility of the new taxonomy to be adopted was important. With no online version envisaged until the next update (which was said to be some years away), the Committee concluded that this proposal would not be considered further.

In their respective submissions, the IOC World Bird List and eBird/Clements had stated their increasing collaboration, and their agreement that a single global taxonomy was desirable. On the latter point the International Ornithologists' Union (IOU) has stated that it intends to hold a session at IOC2018 in Vancouver, Canada, in August 2018 which will look at ways to progress to a unified global taxonomy.

This left the Committee with two alternatives: HBW/BirdLife on one side and IOC World Bird List and eBird/Clements on the other. Arguments were advanced in support of both alternatives, and the BOURC members at the meeting were evenly split between adopting either HBW/BirdLife or the IOC World Bird List. From a show of hands during which the Chair abstained, there were four votes on each side. Each member of the Committee then summarised his or her reasoning, and members were given the opportunity to reconsider their vote.
