A short quiz about a picture

In the picture above there are three men:

X - one who looks like he is in the process of swallowing a crow
Y - one who looks like he is trying to digest a crow
Z - one who looks like he just succeeded to feed two persons with two crows

Assign numbers to X, Y and Z (from left to right, please)

Update: Another picture, with a person that caught the crows and wrung their necks. But it's elementary, my dear Watsons, so no prizes for that one.
