Presumably the other three spend the night in the west-nest tree in the lowest nest located there. We saw wrens working around the nest remainder in the east-tree and think that they may be gathering material to use in construction of a nest which is being constructed at the lowest fork of the same tree. - Hunted about .5 mi.
