Ebony bird call

In the morning, I wake up in the tent with the voice of a bird that I can hear just by separating a piece of cloth.
 It's one of the real thrills of camping, isn't it?

 A bird call that appeals to birds by making a squeak. I made it with ebony.
 It is a work of ciia, a writer of wooden lathes. Comes with a leather strap.
