ticking sound

Last couple of days I heard a ticking sound in my garden,
at first I could not figure out...what it was.

Then I remembered...
I slowly sneaked to the place where the sound came from.

Yes...!
A song thrush (zanglijster)...hammering a snail...!
hammering the house of the snail so long on the stones..till it breaks.
having his delicious snack...
