Another Cuckoo
FAN-TAILED CUCKOO Cacomantis flabelliformis
Spring is the time to catch sight of cuckoos and this one is a Fan-tailed Cuckoo.
It is quite similar to a Brush Cuckoo but the difference can be seen in the broader white barring on the underside of the tail with white spots on the upper parts of the tail.
The Fan-tail also has a vivid yellow eyering.
This bird is a female. The male is more highly coloured on from the chin to the belly. The female's belly is more rufous in clouring.

Cuckoos
PALLID CUCKOO
Spring has finally arrived.
Several days ago, I could hear cuckoos calling from the tops of trees along the Dry Creek, just south of Broadford. The call is very distinctive, notes rising semitone by semitone.Hence the common name 'semitone bird'. Its call is repetitive and monotonous, going on and on and on. It is sometimes called the 'brain fever' bird after this constant calling.
All Australian cuckoos, except the Pheasant Coucal, which is not found in Victoria, are brood parasites. They lay their eggs in the nests others, leaving these smaller step parents to brood and raise the usually much larger young.
I have watched a Yellow Robin, feeding a young, but much larger than itself, cuckoo hatchling. How hard must it be to keep up with an ever hungry youngster of a huge size?
The semitone bird is a Pallid Cuckoo Cacomantis pallidus. Whist it is reasonably common, it is much more visible in the Spring, during mating time, when its call,from the top of trees or posts,lets us all know to another perch and continue with its song.
