The specimen illustrated had the misfortune to fly into our lounge room window in early December 2005. The bird was stunned but after being photographed recovered and flew off.
We have observed a pair of Blue Wrens raising a Horsefield’s Bronze-Cuckoo chick. The fledgling mimicked the actions of the Blue Wrens by staying close to or on the ground. The chick was at least twice the size of the surrogate parents. They were kept extremely busy feeding this voracious monster.
The Shining Bronze-Cuckoo is similar in appearance.
