It was a scene that reminded me of the classic bit in the Jungle Book film where Kaa the snake is trying to hypnotise Shere Kahn the tiger. He goes through his eye twirling, th-th-inging routine until a bored Shere Khan just splats Kaa's head under a huge paw and says 'Oh, I haven't got time for that sort of nonsense'.
The story of the Purple Gallinule at S'Albufera is interesting. Hunted to extinction here, a re-introduction programme began in 1991 with 28 birds released. By 1999, there were 200 pairs.
