Cute little thing. Not sure if it was a fledgling or not but it didn't seem able to fly. Managed to get the cat inside and the bird hid behind a tree. I went back a little later and it was still there but had disappeared by the time I went to try and put it in a box to either go to the vet or move to a highler location.
Apollo was suitably unimpressed that he wasn't allowed back out. He's just rolled over with a sigh.
