First: Don't let an empty birdhouse fool you - that's not the cache! You will know when you've found the correct Avian Cottage.
Next: The coordinates will take you to a grove of trees between Hwy 18 and Stratus Ave.
While you'll find avian cottages that look fairly new and several that are showing a bit of age, there's one that you seek... Be prepared to scratch your head, cross your eyes, look perplexed, etc. etc.!
But we are not telling you which cottage contains the cache. This is a difficulty of 5, after all!
On the correct cottage, you'll need the right motion.
How does this gadget work?
What's it take to gain access?
Excessive force is not needed!
Use your eyes and hands; no tools needed!
Have fun searching and trying to gain access.
Note that you might find some are occupied by the namesake of these cottages!
