Wedgies being at the top of the heap will not get out of the way. You can even fly right up alongside them in formation and they are not really concerned.
After they released calicivirus to kill rabbits in Australia it took away some of the food chain for Wedgies and the easier option for them was "road kill". Some horror stories of them being run over by vehicles for the same reason.
Not relevant in this case so much but with later types of helicopter that are much quieter it is a bit disconcerting how close you can get to some birds before they move out of the way to the point where you actually need to change the way you operate in some areas and/or be aware of it.
