Tree Swallows (Tachycineta bicolor) have been back in the neighborhood for a few weeks. They have been checking nest boxes around the garden but they have been chased out of each nest box they tried by the House Sparrows. In turn, we chased the Sparrows out. It’s a spring ritual that we have to do in order to secure a place for the songbirds.
Finally, a pair of Tree Swallows settled into one of the boxes. Hopefully, the other two pairs will not be discouraged by the Sparrows and will find another place to raise their families. We had three Swallow families in our garden last year and they tend to come back to the same place year after year.
The female has been building her nest for the last few days. Her mate keeps an eye on the intruder Sparrows. It’s fun to see her selecting nest material and trying to get it into the nest box.
Welcome home kids.
