For the last few years when driving past the man-made lake on Mounts Bay Road in Perth I’ve wondered why all the trees are white.
The kids always ask me why, and I, like the guy on that ad – you know the Great Wall of China is to keep the rabbits out guy – make up some rubbish because I don’t know.
Like: “It’s the dust from the roadworks where they are building the railway.” Which of course didn’t hold water after the railway was opened last year…
The other day I decided enough was enough. I was going to get to the bottom of this for once and for all. I stopped the car, got out and investigated, Nancy Drew style.
These trees look as if they have been spray-painted and now I can reveal that they have… in a way.
This bird – and his mates – are the culprits. Up in the branches there is a colony of these black birds (does anyone know what they are)… and that white stuff?
You got it. Guano. Birdshit.
Doh! I should have guessed that.
It was, perhaps not surprisingly, very obvious. It coats the trees from the top to the ground – I’m surprised they can photosynthesise at all.
Just call me Nancy.
