Since he's close to shedding, it could certainly be a piece of loose skin in his nose causing him to whistle a bit. That'd be perfectly normal too.
Lol that would be a wierd sound if its coming from the end because it was loud and definitely startled me. hopefully it is just the shedding and not anything else. This would be my first shed with him
