Juvenile wren

Bewick's Wren (pronounced 'Buick' like the car) was named after a friend of Audubon's long before the automobile was built. If I've correctly identifed it, it is a West Coast wren, common west of the Cascades in Oregon and Washington and in the Southwest and Mexico.

The Bewick's Wren is a year-round resident, while the house wren migrates to Mexico for the winter. Not seeing a wren in the winter doesn't prove much; however, as the Bewick's wren will move around to lower elevations, even though not migrating as such.

The first 3 photos show a parent Wren transporting an insect to a juvenile.
