The IOC World Bird List 5.4 contains 10,756 (10,763?) species classified in 241 families and 2282 genera.

Hume's Owl Strix butleri on stamps changes English and scientific name to Desert Owl Strix hadorami. The reason for this is that Hume's Owl is split - the southern populations keep the scientific name Strix butleri with new English name Omani Owl, the northern populations are renamed Desert Owl Strix hadorami (Israel 1987.01-2, Mozambique 2013.11, Sao Tome & Principe 2003.08, St Vincent & Grenadines 2001.07).

Micronesian Kingfisher Todiramphus cinnamominus is split to three species.
Guam (Micronesian) Kingfisher Todiramphus cinnamominus: no longer on stamp
Rusty-capped Kingfisher Todiramphus pelewensis: Palau 1994.02, 2000.01, 2007.01
Pohnpei Kingfisher Todiramphus reichenbachii: Micronesia 1990.01, 1991.03

Tuamotu Kingfisher Todiramphus gambieri on stamps changes English and scientific name to Niau Kingfisher Todiramphus gertrudae (French Polynesia 1991.01, 2010.01). The reason for this is that Tuamotu Kingfisher is split - the extinct Mangareva Kingfisher Todiramphus gambieri and Niau Kingfisher Todiramphus gertrudae.

Five splits from Collared Kingfisher Todiramphus chloris are accepted.
Mariana Kingfisher Todiramphus albicilla: Guinea-Bissau 2012.15
Melanesian Kingfisher Todiramphus tristrami: Solomon Is 2004.03
Pacific Kingfisher Todiramphus sacer: Fiji 1994.01 1995.01 1995.03 1996.02, Niuafo'ou 1983.01 1986.01, Niue 1992.02 1993.04 1996.01
Other birds listed by me as Collared Kingfishers should probably be listed as belonging to some of the new species.

Several subspecies of Variable Dwarf Kingfisher Ceyx lepidus are raised to species level.
Variable Dwarf Kingfisher Ceyx lepidus is no longer on stamp.
