I'm housesitting for a friend and her cat didn't come in until late last night. I heard it come in and went to the kitchen to find one dead chick and one live chick that had just been brought in by the cat. I retrieved the chick and put it in a tissue box with a heat pack under it and a woollen sock tucked into the opening. I took it to a vet today, under advice from Sydney Wildlife Rescue, and I will check in tomorrow to see if it has survived.
This observation is for the bird you can hear through the audio (and not the child at the very end squealing). :)
Not sure on ID and only have these two rather terrible photos!
