I am sure Martin is right about the every known Koel-host in the Canberra area has been Red Wattlebird. The Koel has only been breeding in Canberra since about 2009. This appears to have increased fairly steadily since then. This is about 10 years after they started coming here in regularly increasing summer numbers. So presumably it is a new problem for the local Red Wattlebirds. About a question whether they parasitise Magpies. Apart from lack of evidence of this, I doubt it. To go into the general: cuckoos parasitise species smaller than them. Are there exceptions to that generalisation?




The Red Wattlebird is their main host in the Blue Mountains (NSW) too. It’s also by far the most common of their potential hosts in the area.

I think I am correct in saying that every known Koel-host in the Canberra area has been Red Wattlebird - although one observer is keeping an eye on a Koel that he in turn been keeping an eye on some Magpie Larks.  That being said where I live, a few kms out of Canberra and about 200m higher, a female Koel arrived in the area a couple of weeks ago and we have a Noisy Friarbird building a nest at present.

Hi Bill,

HANZAB doesn't list Australian Magpie as a host. The three most recorded parasitized birds were friarbirds, figbirds and magpie-larks. Red Wattlebird was listed too. This was published in 1999, so before the big wave of range expansion into Victoria we have seen in the past decade, so perhaps wattlebirds are parasitized more often in Victoria?

Hi all, Bill here

Following my post about Koels, I’ve had a question about whether they parasitise Magpies. I thought they concentrated on larger honeyeaters.

Does anyone know? I don’t have HANZAB to hand, unfortunately.
