3. The dress of a hawk

A falconer wouldn't be seen dead with a badly dressed bird. Time to invest on some proper attire:

Bewils. The leathers buttoned to the birds legs, embellished with the hawk bells.

Creanse. A thin twine fastened to the leash in disciplining a hawk.

Hood. A cover for the head, to keep the hawk in the dark. A rufter hood is a wide one, open from behind. To unstrike a hood is to draw the strings so that the hood can be easily pulled off if so desired.

Jesses. The little leather straps with which the leash is fastened to the legs.

Leash. The leather thong for holding the hawk.
