Songs and calls of the Golden-crowned Kinglet (Regulus satrapa) from a
number of locations in Eastern North America were examined. Songs wer
e comprised of a variable number of six syllable types. The order of s
yllable presentation, however, was highly predictable both within and
among individuals. Song structure resembled that of the congeneric Fir
ecrest (R. ignicapillus) of Europe. Two common calls of the Golden-cro
wned Kinglet (ti and zeet) occurred throughout the geographic range ex
amined and strongly resembled calls of the Firecrest and Goldcrest (R.
regulus), as well as having similar putative functions.
