Carolina Wren
Copyright © 2005 Jerry Kumery

Conservation Concern: NONE

Population Trend: Poorly Known
Credibility: Very Poor

The Carolina Wren is an uncommon to rare breeder in the CW Region which is on the far northern fringe of its range.  Populations here often have difficulty combating harsh winters, but BBS trends indicate that the Carolina Wren's numbers are still increasing in our area.  Nesting usually takes place in woodlands with adequate low understory - often near water in sheltered ravines.  BCN eBird trends also show a notable increase, but the standard error is very high for this species.
