I was out walking doggo last night and three kids stopped me to tell me that they'd found a kookaburra in a box. Weird, but okay. Turns out there was indeed a kookaburra in a box. It was a fledgling bird, hunkered down in the back of a cardboard box, on top of a folded towel. Ordinarily, I'd leave a young bird be, but someone had obviously intervened already, so I called a wildlife rescue helpline for advice. They couldn't reach anyone in Perth (typical), but suggested I take the bird home and seek help the next day (today).
I took muttley home and got my gardening gloves and went back and scooped the box with the bird inside. It had a bit of a nibble at my fingers, but was otherwise chill. I put it in the courtyard at the back of the house and put out a little dish of water. This morning, it was out of the box and exploring the courtyard, which I took to be a good sign. It could flutter around, despite not really having much of a tail yet and managed to get up onto the outdoor table (also a good sign). I called the Department of Biodiversity, Conservation and Attractions for some advice and they told me that I should contact another wildlife carer organisation. I did and was advised that if the bird seemed healthy enough, the best thing was to just let it go in a safe location.
We tried to feed it some little pieces of meat, which it took, but tried to thrash around, so it didn't actually eat. It would seem that's a behaviour for dealing with prey like insects, small lizards etc., which probably bodes well. So, this evening it was back in the box, so I scooped it up again, took it to a little patch of bushland away from the dog park where I found it and let it go. It fluttered back and forth a bit and it settled on the edge of a basketball half court, which looked like it sees very little use. I left it at that point and just hope that it can feed itself. Fair thee well little bird.
