Mlíkovský J. / Faunistic work of Josef Prokop Pražák Faunistic work of an ornithological swindler, Josef Prokop Pražák (1870–1904): an assessment Zhodnocení faunistického díla ornitologického podvodníka Josefa Prokopa Pražáka (1870–1904) Jiří Mlíkovský Department of Zoology, National Museum, Václavské náměstí 68, CZ-115 79 Praha 1, Czech Republic; e-mail: [email protected] Mlíkovský J. 2012: Faunistic work of an ornithological swindler, Josef Prokop Pražák (1870–1904): an assessment. Sylvia 48: 152–161. Josef Prokop Pražák (1870–1904) published faunistic data on the birds of Austrian East Galicia, China, Chile and Bohemia. Many of these data are highly improbable or even demonstrably fraudulent. As shown elsewhere (Mlíkovský 2011), Pražák was a deliberate swindler from the beginning of his scientific career to the end of his life. Pražák was a talented ornithologist and some of his faunistic data may be genuine. However, such a large amount of the data he published is demonstrably or probably fraudulent that none can be accepted as valid, because there is no way how to discern between Pražák’s genuine and fraudulent data. In 1893 and 1894, Pražák donated voucher specimens of some of his Bohemian “rarities” to the Naturhistorisches Museum Wien, Austria. At least one of these specimens had been previously stolen by Pražák from the collections of this Museum. Thus, none of these specimens can be used as evidence for the occurrence of the species in question in Bohemia. Josef Prokop Pražák (1870–1904) publikoval faunistická data o ptácích rakouské Východní Haliče, Číny, Chile a Čech. Mnohé z těchto údajů jsou vysoce nepravděpodobné či dokon- ce prokazatelně zfalšované. Jak jsem ukázal jinde (Mlíkovský 2011), Pražák byl vědomým podvodníkem od počátku své vědecké kariéry až do konce svého života. Pražák byl dobrým ornitologem, takže některé z jeho faunistických údajů mohou být pravdivé. Z jeho dat je však takové množství prokazatelně či pravděpodobně zfalšovaných, že žádná nelze akceptovat, zejména proto, že nelze odlišit, které z Pražákových údajů jsou pravé a které zfalšované. V le- tech 1893 a 1894 daroval Pražák dokladové exempláře některých ze svých českých “vzácností” Přírodovědeckému muzeu ve Vídni v Rakousku. Alespoň jeden z těchto exemplářů však Pražák předtím z tohoto Muzea ukradl. Žádný z těchto exemplářů nelze tedy použít jako doklad pro výskyt dotyčného druhu v Čechách.
