Bird Quiz

[kaaliz]

Most of the questions on this Bird-related quiz I got were just anagrams, though some were more tricky like:

From Tellurium and Radon (4) The answer was in their chemical abbreviation Te and Rn.

This is the last one and I cannot get it, or even what it's asking.

Z:NPNJ

Any ideas?

Nothing obvious comes to mind, unless...

Could the letters N, P & J refer to previous answers? (Assuming the answers are lettered A-Z)

You might have more luck in Quizzes and Puzzles - there are some clever people there.

Thanks, but the previous questions were just numbered. I didn't even notice the Quizzes and Puzzles section. I'll give it a try. Thanks again.
