Nathanael,

 

There is a research going on into this locally, see message by Virginia Abernathy [] from 3/9/2015 which I have copied below: So in answer yes we know and it is particularly interesting as to why they are so restricted here and to look at if and how the RW are adapting. About your suggestion of magpies, currawongs, black-faced cuckoo shrikes and crested pigeons as well as the hollow nesters like the nearby rainbow lorikeets and galahs. Cuckoos generally are very selective and those choices you mention are way out for a Koel. Also most Cuckoos around the world mostly parasitise birds much smaller than themselves, so the bit you note about it looks rather difficult for a large koel to manoeuvre down to the nest is very ordinary for them, though they have developed ways of doing that too.

Dear COG,

I am an ANU PhD student working on koels in both Canberra and Sydney. Some of you may already be familiar with my research, but just in case you are not, I am looking at how quickly hosts of the koel can evolve defences, as the koel is a relatively recent addition to Canberra and only recently began using the Red Wattlebird as its primary host in Sydney and Canberra. I've been conducting nest experiments at wattlebird nests, as well as at nests of two older hosts: the Magpie-larks and Noisy Friarbirds.

During the first year of the study in Canberra, the COG members were incredibly helpful and encouraging, assisting me with locating nests and koel fledglings. This year I will have two field assistants in Canberra while I remain in Sydney. I have CCed both of them on this email so you can get in touch with them directly. My request is if you happen to find any host nests, host fledglings, or see koel activity (especially female koels, koel fledglings, ect) that you let them know so they can investigate. Any stage of host nest is usable for my project.

Both assistants have been through the ANU Animal Ethics training course and have all the proper permits and experience for conducting this work. I have also been/will be training them before they start work on their own.

I thank all of you for your help in the past and look forward to a great and exciting new season!

Cheers,

Virginia

 

May the koels be with you!

Do we know if Koels prefer Red Wattlebirds as foster parents and their nests for laying their own eggs? It sounds like a popular choice ... but given the location of the nest across the road from me where I've been watching a koel grow up over the past month amongst a dense pepper tree it looks rather difficult for a large koel to manoeuvre down to the nest so it must have been particularly attractive over the other nearby nests of magpies, currawongs, black-faced cuckoo shrikes and crested pigeons as well as the hollow nesters like the nearby rainbow lorikeets and galahs.

This afternoon there has been a young Koel in my yard, indeed just outside my window. Only calls are a simple weak squeak. Perched in dense bushes among grapes. Able to fly but not too keen on flying. I just saw another either young Koel or adult female and a RW go near it at the same time. I think the RW fed it but too hard to see among all the fluttering in the bushes.
