Maybe Red Quru is a male in mating season (Like Hypnock) who changes color. While in this mating mode he suffers a deficiency in a certain type of mineral. Therefore he must drink from the mineral-rich volcanic water to restore these minerals. They may even accumulate on his wing tips, and the mineral may be highyl conductive of electricity, so when banged together create a spark of electricity. The flash maybe used to attract mates from far away or makes his presence known. I dunno, it sounds plausible to me.

I'm just laving my message from the chat here to spark some discussion.
