All I know is that I have to net my cherry trees in the spring otherwise the sparrows decimate them. Other than that they don’t bother me. I have two families of Juniper titmouses that come back every year to a couple of birdhouses under my grapevine pergolas. They eat bugs.

I get the point, and it’s terrifying, but -

For the first time in the last say 10 years, my backyard is full of chickadees (a close relative to the sparrow).

"Sparrows seem to have fallen into a bit of a decline for the time being."

Sparrows and many other kinds of animals, because of the plague of feral and domestic cats.

It’s not just sparrows, all the songbirds I grew up with have disappeared.

It doesn’t help that there are 40,000 cats in Key West—a major nesting flyway from Latin America.

A few years back, I had the fortune of having a front porch in the shade and a pair of nesting bluebirds in a birdhouse I had built and installed on the front lawn @ 20-30 yards away.
When the sun hits just right, the bluebirds were brilliant, beautiful.
I'd just sit there with binocs and enjoy. So so peaceful and relaxing, I had no idea!

Then the sparrows drove them out and broke their eggs.
