I just watched a heron catch and eat a frog from the garden pond. The presence of the heron isn’t unusual, but they’re generally both shy and uncannily good at spotting people, even through glass and at some distance. It took it some time to eat the frog — presumably mainly because frogs are quite an awkward shape, especially if you only have a beak to control them with — and several times the heron dipped it into the pond. I’m tempted to say ‘washed it in the pond’ but perhaps that’s not what’s going on. After all, the frog just came out of the same bit of water, so it doesn’t obviously need washing. Perhaps they just wash all their prey habitually? Or perhaps wet frogs are easier to swallow? I don’t know.
