The Stuffed Falcon is treasure that can be obtained in the episode In the Air Tonight in Sly Cooper: Age of Thieves. It is worth 244 coins and the time needed to reach the safehouse is fourteen seconds.
"For a long time, this falcon flew with a group of other birds until a smelly skunk thief shot it down one day. No one looked at it the same way after that, and it became lost after a visit to the taxidermist. However, it has been found again, and it will now be cherished for generations to come."
It is located underneath of the safehouse. Only Penelope can obtain this treasure.
