Even though we removed the beginnings of about 10 nests in the early spring, the mother succeeded in building one overnight right outside of our entryway door. Sure enough, she worked hard to nest 4 tiny eggs and soon ennough four little mouths peeked over the edge and we watched her drop worms into the open beaks. It is absolutely amazing to see the work and growth of a new family and all too soon...they flew the nest.
We had two nests, actually. The other was on the back deck and the mother would try to swoop us every time we took a step back there. I could watch her from the basement window while sitting on the couch. I bet she fed her babies every 20 minutes for several days.
