I have not had a problem with my S, but I once hit an ibis in a F1 Brabham Repco.

On a private test day at the Surfers Paradise circuit in Queensland Oz, I was accelerating out of a 125 MPH corner when it flew low across the road in front of me. I hit it with the upper wishbone in an explosion of feathers, which fortunately accelerated it somewhat, before it bounced up enough to hit the low Perspex screen.

It smashed a couple of moderate pieces out of that, & was lifted enough to hit my helmet, above the visor pretty hard.

I think the roll over bar behind my head probably saved me from a broken neck. My head was bashed back into it hard enough to put a 6" crack in the back of my helmet.

The large bit of ibis still together followed on through the roll over bar, into the air scoop, where it bounced down into the valley between the cam covers. Some then went out the back of the engine cover, but enough stayed behind to be cooked by the heat of the engine. Believe me the smell of cooked ibis is most definitely not appetizing.

No serious damage was done, apart from the ibis. A new screen & helmet were required, but that ibis continued to get his revenge for a number of months. Despite much scrubbing & degreasing, every time the engine warmed up the stink of cooked ibis came back to remind us.
