As over the years I have used various taxonomies such as Clements, IOC, BOU and ABA, inevitably issues can arise in the mapping of these species between taxonomies and errors can creep into species lists. For example Setophagea petechia is Yellow Warbler in the BOU taxonomy but in the IOC taxonomy it is Mangrove Warbler. In IOC American Yellow Warbler is Setophaga aestiva. To help spot any such issues it would be helpful if in the species window, in the box where a species taxonomy and other details are shown, for the species name in the secondary taxonomy to be shown.
