species' names described in that period. Meise was of the opinion that between 135 and 200 represented good species. At the ninth IOC in 1938, Meise presented a second paper, listing 23 new species described in the intervening period, plus a further 36 which had been described during 1920–1934 and not covered in the earlier paper. Meise's papers were: Meise, W. (1934) Fortschritte der ornithologischen Systematik seit 1920 Proc. VIII Cong. Internat. Ornith. pp. 49–189 Meise, W. (1938) Exposition de types d'oiseaux nouvellement décrits au Muséum de Paris Proc. IX Cong. Internat. Ornith. pp. 46–51 After the Second World War, ornithologists based at museums in the American Museum of Natural History produced further reviews; again, each of these listed newly described species and presented an analysis, indicating which were and were not good species. To date, six such papers have been compiled; they are, in chronological order: No further detailed analyses have been published since the 1992 paper, although the British magazine Birding World has published two articles by Oscar van Rootselaar listing newly described species since 1990: Discoveries by year 1964 Barau's petrel Pterodroma baraui Greater yellow-headed vulture, Cathartes melambrotus 1973 †Poʻo-uli Melamprosops phaeosoma (now extinct) 1981 Chubut steamerduck, Tachyeres leucocephalus Okinawa rail, Gallirallus okinawae Yellow-footed honeyguide, Melignomon eisentrauti 1982 Mirafra ashi Malurus campbelli Ploceus ruweti Vidua raricola Vidua larvaticola 1983 †Alagoas foliage-gleaner, Philydor novaesi (now extinct) Amsterdam albatross, Diomedea amsterdamensis Glaucidium albertinum Cichloris llaneae Gerygone ruficauda Nectarinia rufipennis Eungella honeyeater, Lichenostomus hindwoodi 1984 West African batis 1985 Red Sea swallow, Hirundo perdita Phyllastrephus leucolepis 1986 Ash-throated antwren, Herpsilochmus parkeri Ploceus victoriae 1987 Cettia carolinae 1991 Roviana rail, Gallirallus rovianae from Roviana, Solomon Islands 1995 Sichuan treecreeper 1997 Lina's sunbird, Aethopyga linaraborae, from Mindanao, Philippines Red-shouldered vanga, Calicalicus rufocarpalis Batrachostomus pygmeus 1998 Araripe manakin, Antilophia bokermanni Sangihe scops owl, Otus collari 1999 Jocotoco antpitta, Grallaria ridgelyi, from Ecuador 2000s See Bird species new to science described in the 2000s. 2010s See Bird species described in the 2010s. 2020s See Bird species described in the 2020s.
