I then reviewed all the bird species listed at https://en.wikipedia.org/wiki/List_of_birds_by_common_name and learned that I’d have to do two new bird chase caches if I wanted to cover all four missing properties.
One of the birds is the “cedar waxwing,” which covers one of the missing properties, but I’ll leave that one for a possible future “chase” cache.
The flyer of this cache is a “triple hitter” – it covers all three of the remaining missing properties.
Once you identify this flyer, determine the alpha-sum (A=1, B=2, etc.) of its common name, of its scientific name and of the language it would likely speak if it were a talking bird. Doubling the sum of these three sums will give you the distance in meters and the bearing in mils True (360 degrees = 6400 mils) to the cache from the posted coordinates.
