For those that keep up with us from week-to-week, you already know we have been lucky enough to have some house wrens nesting out in the yard. As with every year, we place a couple of wren nesting boxes out in the yard and hope that a well-vocalized male selects one of them to raise his family through the spring and early summer months.
As we highlighted in our last post, house wrens are wildly aggressive, given their small size. In addition to actually chasing out larger birds and claiming their nesting sites, these small birds will also sabotage existing sites so as to keep competing males at bay.
This year, one of our boxes was stuffed full of debris. This year, we watched the male over the course of about a week busy filling both boxes, one an act of sabotage, the other with a brood.
