I was sitting at home working a moment ago when I heard the sound of what I thought was a tennis ball hitting the window high up on the side of our house.

I looked up as a bird fell into the court yard, and I watched it as it lay on the ground where it landed and twitched a little before lying still. A indigenous Little Wattlebird, dead.

And I feel faintly ridiculous about this, but the bird dying has upset me a little. I'm not used to watching a creature die. And I'm not used to being confronted by my impact on the natural world as directly as this.

This whole blog is supposed to be about how to make my neighbourhood more ecologically sustainable, but for this bird the fact my house existed at all, with it's unnatural glass surfaces, was enough. And right now, faced with the reality of this little prone body, the life of even one wild bird seems like a high price to pay.

I'm feeling a little guilty.
