The pond in fact had about an inch of ice on it, which was thawing (there was water on top of the ice because of the thaw), so the Heron is in fact stood on the ice. The photo was taken with my Casio Exilim 7.2M pixels at 3x zoom from my bedroom window which is about 30 metres away, and was then blown up in iPhoto. I wish I could’ve blown up the Heron, because not content to be chased off, the assassin (yes, he did kill at least one fish on a previous fishing expedition) returned a few days after the thaw:
Here it is again, a little further away (but there was more light, hence less grainy) up a tree that overlooks the pond. I do admit to being torn, as they are quite beautiful. But I swear that if it eats one more fish, I’ll take countermeasures... Searching on Yahoo Answers reveals a range of options, including adding garlic to the pond, getting a large dog, or my favorite: “shoot the bastard”.
