Bird Strike Testing
(OP)
I am looking for a quality testing house that performs bird strike testing. Can anyone provide some contacts?

RE: Bird Strike Testing
Like a lot of qualification testing, aircraft bird shot testing is arbitrary.
The bird is to weigh 4 pounds and the velocity at impact is the max speed the airplane can fly below 14,000 ft.
So all this assumes so long as the bird's weight does not exceed 4 pounds and is not flying above 14,000 ft, the crew is safe.
Nor does the criteria take into account the direction the bird might be flying at impact.
Let's assume the airplane was qualified to 300 knots. If the bird is flying towards the airplane at 20 knots, the impact velocity is 320 knots. The energy at impact is proportional to the square of the velocity, so the energy at impact would be about 14% higher than the test impact energy level.

When fired into a flat plate, again there was very little if any difference in the amount of impact.

Both birds shattered into a zillion pieces.

Aircraft windshields are not flat panels perpendicular to the airstream.
When the bird impacts the windshield, only part of the energy needs to be absorbed by the windscreen. Most of the energy gets carried off with the remains that are deflected off to the side or over the top. That is why it is important for the bird to be freshly killed and still relatively soft.
To qualify a windshield, it takes several shots at various points considered most vulnerable. Aircraft centerline shots can be the most difficult to pass.
And if you are imagining a bunch of feathers, blood and guts,it does not work that way. At the impact area, it looks like it was painted with a coarse gray paint. The rest is pulversized and not identifiable.
