Chattering wrens (Charles River Peninsula)

The house wrens are taking over the CRP. You can find them everywhere--in the center of the property as well as the fringes. As is their practice, they've colonized the bluebird boxes (and jammed the ones they aren't using with sticks). There is one corner of the property that is particularly sensitive, and they never fail to chatter at me as I walk by. The reason is obvious--they have young ones [chattering too] in a box near the trail.
