Are birds IFR?

I read an article on the CASA website they did DNA testing to find out what
airplanes were hitting from the remaining remnants on the aircraft.

We often talk about bird strikes they said at night bat strikes were common.

Here in Austin where we have the worlds largest urban bat colony, bat
strikes at night are common. I've never hit an actual bat, but I did
have one drop a large fruit object in order to dodge my prop. After I
put the plane away it looked like total carnage - big squishy red pulp
just above the landing light... Until I realized that it was extra
sticky and sweet. Apparently in that little flash of recognition we
both had through my windscreen, the bat dropped his load (I'm guessing
a fig, probably about 2 inches across) in order to climb.
