Something's happened to Holland Park's Parakeet population. They're not there. Vanished. They've been scratched off the canvas of the park.

Sitting in the Dutch Garden, I'd always glimpse a zap of lime green dash from tree to tree, or at least hear them squeaking and squawking.

And now, nada. So where are they? On holiday? Gone somewhere warmer? Pitched camp and headed for another part of town?
