2025 edition -> 2026 edition     IOC bird list v 14.2 -> AviList v2025

[Note: In v14.2 of the IOC bird list, birds that are regularly present along the Pacific coast of Central America and Colombia were incorrectly shown as being of species 142/0845  Brown Booby. This is the subspecies etesiaca, which should have been ascribed to species 142/084E  Cocos Booby. The error was corrected in v15.1 of the IOC bird list. However, in view of the significance of this error for the distribution of the newly-split species, that error was acknowledged and corrected in the 2025 edition of this eBook. Hence, that correction in v15.1 did not impact upon the content of this eBook.]
