In Ontario the Carolina Wren is rare enough to rejoice the bird watcher when found, but, at least in southern Ontario, common enough that you have a fair chance of finding one eventually.
They may be found at any season but are most likely to be located in spring when their rollicking song is to be heard.
This is biggish wren, with rich brown colouration and prominent white”eyebrows”.
It is fond of ravines but is not entirely averse to human habitations.
It has a variety of cardinal-like songs, usually of three syllables, sometimes written as “tea-kettle, tea-kettle,tea-kettle”: it also gives a rolling chatter when disturbed.
