Dragonflies? (countdown - 2!)

This is an obvious confusion of peck 啄 and burn 灼 because both words share the same transcription, i.e. zhuo2. The interesting question is, why translating from Hanyu pinyin, the Latin transcription system, and not from the original character, which clearly looks different ...

I'd translate it as:
"Beware of the pecking birds. Keep your distance."

Many thanks, Li Bin!
