Anyone tuned in to bird songs is aware that the skies become fairly quiet once migration has taken place. 75% of North American songbirds head to warmer climes in the fall and when they disappear, so do their songs. Among those birds that remain in New England year-round are some species that actually continue to sing throughout the year as well. Northern Mockingbirds, Black-capped Chickadees, and Northern Cardinals are among them, as is the Carolina Wren (pictured), whose range has extended north as our climate has warmed.
Male Carolina Wrens sing year-round defending their territory. Unlike other wren species in its genus, only the male Carolina Wren sings. An individual can have from 17 to 55 song types. He will sing a song type an average of 15 times before switching to another song type, usually after a pause in singing. To hear a Carolina Wren, go to https://www.allaboutbirds.org/guide/Carolina_Wren/. How fortunate we are that their voices can be heard now and even in the dead of winter.
