The bird doesn't have to come into the cabin to be a significant proble.
I hit one exactly of the most forward part of an AS355 nose cone. The carcass then slid down and under the belly. Some feathers and guts(?) at the impact site and a disk about 18 inches across still attached at the top but pushed into the cabin behind the instrament panel. The biggest danger was the detritus that blew around with the new vent after impact. Especially the sand, which could have created eyeball problems except that I had my clear visor down.
