In the early summer, I found house sparrows were using the new box. Later, a young one was peeking out waiting for a parent to return.
Babies soon learned to fly and then out into my backyard.
See, even outside of the nest, it still liked to get fed for a while. But pretty soon it learned to get food on its own and become independent.
"Now I can fly over a tall pine tree, Ya ho!"
"I can have a drink whenever I get thirsty!"
"I am enjoying a stroll among dandelions to find a bug."
My mother used to tell me, "Many years ago, I used to get up with a sparrow's chirping in the morning without an alarm clock." Well, although I no longer have to get up early to get to work, House Sparrows still wake me up early in the morning.
P.S. I checked the bird box at the end of summer to see how it looked like inside.
Aha, it is stuffed with everything!! Hundreds of trips to make that comfortable bed. A lot of work required to make a nest.
