The FeatheredFriends are both cachers and avid bird watchers. To find the final cache in this series, you will need to find the clues in the other caches and unjumble them below.

The final coordinates of the cache are:
N 36 0B.IRD
W 079 WA.TCH
If a letter in a red circle appears in the final coordinates, substitute the number at the beginning of the jumble into the final coordinates.
Once you have unjumbled the clues and deciphered the coordinates, finding the cache should be easy.
