This is a photo of an Eastern Koel-Eudynamys orientalis I took this photo of a young juvenile who host 'mother' is a Red Wattle Bird. The nest was in a Gordania tree in my front yard. She is raising this youngster and working very hard to supply it with food. The young Koel was perched on my balcony and it allowed me to get relatively close to take some photos. The baby is much larger than it's host mother and when I saw her feeding it, her whole head fitted in the youngsters mouth. The younster is still around and still calling for a feed. Hope you enjoy my Photograph. Jan Birds facts taken from http://birdsinbackyards.net/species/Eudynamys- orientalis It is a member of the Cuckoo family. Adults are rather shy and they are heard much more than seen. In contrast to the adults, fledglings can be very conspicuous as they beg loudly for food from their foster parents. In late September and early October each year, Common Koels arrive in Australia from their northern winter homes to breed. The Koels leave southern Australia in about March. The Common Koel is a brood parasite, that is, it lays its eggs in the nests of other bird species. Common hosts are the Red Wattlebird,Anthochaera carnunculata, friarbirds, the Magpie-lark, Grallina cyanoleuca, and figbirds. A single egg is laid in the host's nest and once hatched the chick forces the other eggs and hatchlings out of the nest. When the chick leaves the nest it roosts in the outer branches of a tree, cheeping incessantly while the significantly smaller parents desperately search for sufficient food to satisfy the nagging youngster. This is a full-time job, as the young Koel will grow to nearly twice their size. Eventually, it migrates northwards, usually later than the adults, to return as a breeding bird the following spring. Most Koels migrate from Australia to New Guinea and probably eastern Indonesia and even further north, but some remain in northern Australia. During breeding season, they are found in northern and eastern Australia, south to about Nowra, New South Wales, although occasional birds are encountered further south. Koels appear to be becoming more common in cities, such as Sydney and Brisbane, perhaps because of the abundance of ornamental plants and weeds that produce berries. However, another factor that probably contributes to their increasing abundance is the proliferation of some of their hosts, particularly the Red Wattlebird. The male Common Koel advertises its presence by a loud ascending whistle or 'koo-el', monotonously repeated; the call of the female is a repetitive 'keek-keek-keek-keek'. Males often call throughout the day and well into the night.
