iGoTerra has updated the IOC World Bird List to version 7.3. The new version contains 14 species splits and 2 lumped species where noteworthy that Glossy Swiftlet is now split across 8 species. Thayer's Gull has been lumped with Iceland Gull.

For iGoTerra members who use IOC, you will benefit from automatic updates of ALL your lists for Birds! In case you have not yet assigned all your ticks and observations to subspecies, you may have a list of species that you have to manually assign correctly according to the updated taxonomy. These ticks/observations you will find when logged in under Observations => Update my splits and lumps: Birds. Details on the new and deleted species are available on IOC's website where you also are able to see more information of the changes in subspecies so if in doubt where to move your observations on a deleted subspecies this is a good reference.

In order to be better prepared for the next IOC WBL release in a few months, we recommend you to go through your lists with our Bird subspecies assignment tool. You should also refresh your checklists downloaded to Pocket to ensure that the new species are included.
