Bewick's Wren

At the Pismo Beach Butterfly Grove last March, Erika and I also photographed a Bewick's Wren (pronounced like the car). Years ago this wren was common across most of the United States, but has almost disappeared from the East. Now it is most common in southeastern Arizona, central Texas, and southern California. The reasons for this decline are not understood, but may include agricultural pesticides or competition with Starlings, House Sparrows and House Wrens. House Wrens have increased while Bewick's Wrens declined. Now many pale Carolina Wrens are misidentified as Bewick's Wrens. Bewick's Wrens were named by Audubon for his friend, the British engraver Thomas Bewick (Kennedy and White 1997).
