Interestingly, though, if you put in "Yellow-naped Amazon Parrot" those photos don't show up. The capitalisation and hyphens don't matter, but that extra word "parrot" definitely changes the results.
Could be because they are quite common in European collections. For specimens without subspecies-status, Zootierliste mentions 28 current collections, for the Lesser yellow-naped 3 collections and the Roatan yellow-naped amazon is kept at the moment at 1 collection.
From American avicultural magazines I also get the impression that the species is quite to very common in the USA ( at least in private aviculture ).
