Hmmm, I haven't hit any deer or cows, but I have hit four birds. Three in flight (two sparrows and one hawk) and one (gull) on the road.

And then there was that flying melon tossed out of a car going in the opposite direction on RT 1. (I was in a Chevy S10, so who cares?)

No whistles installed in any of the above incidents.

 Birds "get" cars: they see a car
 coming, they get out of the way.
 They're pretty good at that, too: sometimes they'll wait
 until the last
 minute to move, a final peck at that nice piece of road
 kill.
 
 Deer don't seem to be able to determine the likely course of
 a vehicle
 -- they are unable to get out of the way because they don't
 know where
 "the way" is.
 
 Cows seem to be as clueless. At least the ones here that
 I've had to
 wade through.

 entering the road, even if deer do hear them.  After
 all, they almost certainly hear and see the vehicle. 
 When I hit a deer, the things were running around in a blind
 panic.  I had slowed to almost a crawl (annoying other
 drivers whom I guess just wanted to hit the deer anyway,
 they had to see them), and the deer had disappeared back
 into the woods.  I sped up, the deer came back and ran
 in front of me before I could stop.

 conclude from this paper that constantly honking your horn
 is the only effective method to alert deer.  Not such a
