Question about sound heard coming from hive
First year beek here and only one Lang hive.
This hive is doing well & they are evicting drones in preparation for winter.
I was watching this eviction play out & heard a noise from deep within the hive, I don't know exactly how to describe it, but it kinda sounded like a small woodpecker or lil' jackhammer.
Haven't heard this noise before.
It was kinda neat.
Would someone care to shed some light on what I heard?
Edit to add:
No odd tenants within, mouse or snake.
I checked before I added a mouse guard last week.
