Some common terms we use come from falconry. For instance, the
term, 'under your thumb’ comes from the falconry way of holding
the bird's talons under ones thumb to keep it from flying away.
A falcon is fitted with
a small leather hood over the bird’s eyes and head to keep it
from being distracted. From this we get the term ‘hoodwinked’.
Falconers regularly
give their bird a small treat when landing on their hand. Each
time the bird goes to find game, like rabbits, and returns it is
given another treat. After a few sessions the bird is full and
no longer wants to go hunt. It is said the bird is ‘fed up’.
