When asked to name her favorite bird, a young ecologist friend once replied with a smile: “All wrens!” I begin to understand her affection.
Coming home in the early morning, we saw (figured out from the bird book) a Bewick’s wren pulling fibers from the front door mat. Often I attach cat and dog fur, harvested-from-brushing, to the ribes and elderberry, mostly as deer deterrent but available as nesting material.
This time I stuck some in small tufts around the edge of the doormat. A little later I spotted both the Bewick’s wren and (another I had to look up) – a marsh wren. The fur quickly disappeared.
According to “Birds of the Puget Sound Region” (well-used and always sitting by the binoculars), the marsh wren male builds “multiple spherical nests.” The female chooses just one, to line and lay her eggs in.
