摘要
We studied the song of the insular Cyprus Short-toed Treecreeper, Certhia brachydactyla dorotheae Hartert, 1904, and compared it with the songs of mainland populations. The song of dorotheae differs from the Central European and south-west European subspecies brachydactyla Brehm, 1820 and megarhynchos Brehm, 1831 most obviously in the number of elements and elements per second, with the effect that the song of dorotheae appears to have a slower rhythm. Furthermore, the starting frequency and ending frequency of their songs are lower. Our findings provide additional support for the subspecific status of the island population of the Short-toed Treecreeper, Certhia brachydactyla dorotheae, on Cyprus.
