Cipher in the bird cage is very beautiful and peaceful to decode 

Check, if u lucky

i heard the owl thing hahah, that was probably how he knews !!

It's a famous spawn/cipher, survivors kinda like to be here so when you check here you've got 85% of chance to find someone, you don't even need any sound lmao

It was a trait. He noticed it being active so he knew a surv was there.

It was the sound of his owl returning to him
