Carolina Wren – 1/17/11
Observer: Paul Lauenstein
Observation Date: 1/17/11
Observation Time: 3:40 p.m.
Observation Location: 284 Mountain Street
Common Name: Carolina Wren
Scientific Name: Thryothorus ludovicianus
Comments: Following the SFOC walk on Martin Luther King Day (January 17), while sipping hot cider at Vera Cross’s house at about 3:40 p.m., a pair of Carolina wrens appeared out the window. It was only 20 degrees outside. The wrens were flitting in and out of an old, unused flue, presumably trying to stay warm. When they perched on a nearby branch, they fluffed their feathers for better insulation.
The Carolina Wren is sensitive to cold weather, with the northern populations decreasing markedly after severe winters. The gradually increasing winter temperatures over the last century may have been responsible for the northward
range expansion seen in the late-1900s and early 2000’s.
A pair bond may form between a male and a female at any time of the year, and the pair will stay together for life. Members of a pair stay together on their territory year round, and forage and move around the territory together.
