Over recent weeks we have heard one or two Horsfield’s Bronze-cuckoos calling from various vantage points on our property or nearby; their call usually carries well over a hundred metres. On one occasion I saw two in the tree shown in the photos here. One was chasing the other so I suspect that mating was imminent. The tree in question is about 40 metres from our back varanda.
Most of the various cuckoos in Australia are like the true cuckoos of Europe except for their call. They are parasitic breeders, laying their eggs in the nests of a wide range of host parents who then incubate the eggs, hatch and raise the young. In many cases the cuckoo will dispose of the host bird’s eggs, or the cuckoo chick will hatch first and remove the eggs or young as the hatch.
We also get the Pallid Cuckoo and the Fan-tailed Cuckoo in our area most spring times but I haven’t heard either of them yet this year. On only one occasion we had a Shining Bronze-cuckoo in our garden, and it is possible to have the Black-eared Cuckoo here too, but I’ve yet to record that species on our block of land.
