Identification - This small wren, which is smaller than a sparrow, has brown upperparts and brown-washed underparts. It is stockier and buffier than its relative the Marsh Wren and has a buffy undertail and lacks a conspicuous white eye-stripe. Faint streaks on the top of the head are very difficult to see, as are streaks on the back.
Morsels - Most birds have monogamous relationships where the pair stays together at least during the breeding season. Others, like the Sedge Wren, have a polygynous relationship where the male mates with more than one female. Since the female tends to choose her mate, she wants to make a choice that will ensure the success of her raising the young. Thus, some females will choose an already mated male that has a productive territory rather than a bachelor male with a less productive territory.
