... or is it because there are fewer bugs these days? I remember car
windshields getting so covered with bug splats that you had to clean
them several times a day. That was 50 years ago. Doesn't seem to
happen today.

For that matter, I remember seeing huge flocks of birds as well. Don't
see many these days.

The birds all starved because there were no bugs to eat:-}

I don't see a lot of bugs in town or on the main highways, but anyhing
more rural brings out a flock of them.

There was a story in "Air and Space" magazine about a plane fitted
with an optical glass bubble for air to air movie work. They covered
the glass with paper to protect it from bugs on takeoff, then tore off
the paper at altitude before they started filming.
