While this has occurred for the past three years at least, i.e. Wattlebird raising a Common Koel and nesting in a nearby very tall bottlebrush tree, this was the first sighting of a new babe'! I guess the young Wattlebird siblings have flitted about in-cognito, and not nearly as obvious as the noisy Koel turns out to be.
now its left wondering where Mum has shot through to?!
it became very windy a while later when I went back for some more photos, and the Koel was holding tight while keeping its feet warm it seemed
then it started to shower, and I could hear the Koel singing out as I retreated. I'm sure it's days of being tucked snugly into a nest now are well gone.
It was March last year, when I was lucky to pick up photos of the Wattlebird nurturing the Common Koel, shown in this blog post, at the same location. When I note it being March, I'm curious now, about such an extended breeding season? Poor Mums!
