Buzzcutter

A strange, bird like creature. They often appear in groups of three or more, against the bottoms of platforms or the tops of tunnels.

Behavior
One of the few flying enemies in the game, Buzzcutters are faster than Bats and harder to kill. They can move through walls and platforms, and can sometimes be alerted of you through the radius of effect on bombs or skills. They will fly close to you and pause, open their mouth, then deal a biting attack. They can be extremely dangerous in large groups or tight spaces as their attacks cause the stun debuff and, their attacks charge about as fast or faster than the stun wears off. Bombs which cause freezing will slow them, making them easier to hit, but it can also freeze them in walls or platforms which makes them almost impossible to kill. The only way to avoid them is to kill them as soon as you can, jump down platforms, move around tunnels quickly to position better, or poison them.

Since the climbing speed of the player is quite slow without a speed buff, climbing away from them is ill-advised. Putting a turret of any kind down near them can draw their attention away from you, opening them up to easier hitting.
