Birds at Altitude

I have been picking up swarms of mosquitos at 5500ft this year.
That is a first.
I often see Blue Herons at 4500 ft.
Seems like every year they are getting higher.

What's the highest altitude that you ever saw a bird swoop past your plane?

The other day I was flying at 5000' MSL, over land that was mostly about
1000' (so 4000' AGL) and saw a flock of birds, hawks of some sort I think,
one of which came close enough to make me quite nervous (although from the
way he was flapping I think he was much more nervous than I was).

I don't think I've ever seen birds above 3000' MSL / 2500' AGL or so before
and I was pretty surprised...

Do birds typically stay low, or have I just been lucky until now?

I have inspected other B-52s where the low level flock of ducks came
through
the radome and into the crew compartment.. not fun.

Sounds rather messy...

Had to ride through a 4 engine approach once... and they were all on the
same side..

What's the minimum number of engines required to keep it aloft? Probably
different number if they are all on one side vs split between both rights, I
guess...
