penguinphloppers: Archiving this one. Alas its protection has been mown down, and not it is sitting there unprotected to get muggled over and over. Here is a picture of the cache container for closure. I am donating the "bird lab on wheels" to "real" birds who might actually take advantage of it.
For future reference, the solve was a matter of converting the birds to their latin counterparts (*Genus species*), then mapping that to a chemical symbol, then mapping that to the periodic table. Image search could be used to figure out the species. There are a few direct hints for disambiguation.
