I've nearly hit birds flying (and actually hit one but at night). They're actually not bad at avoiding aircraft going 100+ mph. They'll tuck their wings and dive if they feel they're in danger so typical training is to pull to avoid a strike (and lower the chance it impacts the windscreen). Obviously not all birds are great at this, particularly the larger ones but they do seek to avoid aircraft generally.
