Ruby-crowned Kinglets (Regulus calendula) invade the hardwoods around Peck's Lake [Arizona] in the Fall. This sample is of a small flock in October, 1997. Listen for the funny little "talk" at the beginning - it's not heard as often as the chattering later.
The Spring Songs of Ruby-Crowned Kinglets are much more melodic and variable than at other times of the year. In this sample a male flits and flys around an admiring female at Tavasci Marsh [Arizona], March 16, 1998.
