This year, I had the good fortune to see both brown-headed nuthatches (Sitta pusilla) and Eastern bluebirds (Sialia sialis) raise broods in some of my nest boxes. I saw the babies fledge, which was truly an enjoyable event.
For some time, the parents continued feeding their babies after they left home, but eventually they got to the point that they could catch or find their own food. As summer progressed, the parents and children both visited my feeders and it was gratifying to see the families thrive. Then during September and October, I saw a behavior that I don’t remember from years past.
The nuthatches started to return to their nest box almost daily. They didn’t check out nearby boxes but went to their original home and today they are still visiting there, sitting on top, fluttering around it and looking inside.
Their frequent visits seem to have intrigued a local tufted titmouse (Baeolophus bicolor) who decided to take a look in their box, too,but that was only a one-time visit as far as I could see.
It’s not only the parents doing this, but also one or more of their offspring. So how true is the saying “you can never go home again” (origin a novel by Thomas Wolfe)? It originally meant that you can’t recapture exactly how things were in your youth because changes take place in situations and places. But people do often journey back to the places where they grew up and apparently birds do, too! Maybe they are wondering if their nest box is still the same good place for a home.
The bluebirds began doing the same with their home nest box as well. They take turns flying from nearby branches to cling to the box and investigate the now empty dwelling. While the nuthatches just lean and peer inside, the bluebirds eventually go inside for a bit.
Oddly, there seems to be some contention involved. For example, when this pair was investigating, they had a little tiff for some reason.
I can only guess that the birds are checking out the nest boxes in anticipation of next year’s nesting season. The nuthatches and bluebirds will begin breeding again around March, although nuthatches might already begin building a new nest as early as December. It will also be interesting to see if they end up roosting in the boxes during the colder winter nights.
Watching the nuthatches and bluebirds nest, fledge and feed is an enjoyable pastime and I’m looking forward to seeing them repeat the process next year. In the meantime, perhaps I’ll continue seeing them around the nest boxes this winter – as Pliny the Elder said, “Home is where the heart is” and something is sure attracting them back! (And yes, I know, that is a bit of anthropomorphizing.)
