Identification - This wren is smaller than a sparrow. Of all the wrens it is the grayest and lacks distinct markings. It has a very faint eyebrow stripe and ring and its heavily barred tail is without white spots.
Morsels - House Wren pairs have been observed destroying the nest, eggs, and even nestlings of other House Wrens and other species that nest close to their territory. The behavior, which is inhibited in mated males and breeding females, is thought to have evolved as a result of competition for nesting cavities.
