Hi I took these photos in the Boolarra State Forest this morning. The chick was being fed by an adult Yellow Robin. The chick looked very big compared to the adult Robin and I am wondering if it may be a cuckoo chick? We have the Fantailed Cuckoo and the Bronze Cuckoo in the forest.
I think that is the juvenile robin, fully grown in size but only just fledged and not yet independent. I'm happy to be corrected though.

Looks like a young Yellow Robin to me.
