Hello,

It appears in the latest release of Ender Zoo on CurseForge, the mod does not have a sound file for when the owl dies. It just plays the normal sound or no sound at all.

Looks like it has only three sounds registered, two ambient and one hurt sound

but the death sound should bejust the hurt sound

So youre right, it does play the normal sound on death and not a unique sound. would be a nice feature to add
