Carolina Wren

Except for posting a photo, I find I have not blogged much about Carolina Wrens. The species is abundant in the American southeast and in parts of eastern Mexico. Here in the upper midwest, this wren is casual throughout the year. I have heard its ringing “tea-kettle, tea-kettle” call once in Minnesota and I seen it a few times in South Dakota. Swanson (in Birds of South Dakota), suspects that most records in that state are the result of post-breeding dispersal by young birds from southern breeding areas.

Perhaps due to warming climate, Carolina Wrens have expanded their range north since the late 1800s. These wrens, however, do not survive cold winters. They do quickly recover from winter setbacks, as they often nest up to three times during the summer, and nests with four or five eggs are the rule (Haggerty and Morton 2014).

This photo appears to be a February 2011 shot taken at the Corkscrew Audubon Sanctuary in Florida.
