Well everyone has its own opinion, and mine is that (Despite not being a fanatic wildlife protector) such a stupid thing as trying to set up a new guiness record in domino falling is not worth the life of a single sparrow. I don't know what Skybird meant when he said he felt so sad, but personally I feel very SAD to see that our human race has reach a stupidity level such as to consider a guiness record in domino falling a matter of life or death for an innocent sparrow that with no trace of harming willigness steped over it.
Some people should stop for a second and rethink a bit about their lives if they are so immersed in consumism, pleasure life and lack of moral references as to consider it justified to perform such an action. Though I agree that punishing this crminally is a bit exaggerated, as the moral pain the author should feel -if he was rational enough- should be enough. And if he is not rational enough to understand this, well, then he has already received a much more severe punishment by the nature.
