Abstract
Three new species appeared in the Hungarian avifauna in 2013: the Black-throated Thrush, the Booted Warbler and the Caspian Plover. A Black-throated Thrush stayed at the Nagyerdõ, Debrecen between the 1st and 12th of March. A Booted Warbler was trapped and ringed at the Hortobágy Fishpond on the 25th of May. Finally, a Caspian Plover was observed near Kardoskút on the 15-17th of November. Thus the number of bird species known to occur in Hungary has increased to 409.
