This cache is for the birds!
They're on the sign here and they are all around, simply solve the mystery and find the cache.
Check out the birds on the sign, look closely. There are several you might see close by such as the Great Egret or an American Coot.
My favorite the Great Blue Heron, and I guess the next would be a Tri-colored heron or Anhigna (sometimes know as the duck bird)
Or sometimes if your not lucky no birds at all?
Well I have given you all you need, now go enjoy the view, the birds and find the cache!
