Cuckoo coincidence

Greetings from Darwin!  I'll be in your city at end March, hence my interest in your group.  Last time I was there you gave me directions to my first Superb Parrot!

Regarding Koel - the incidence of This Cuckoo increasing appears the same throughout Australia - certainly in the NT anyway.  I had a male bird calling this morning and have heard one on several occasions nearby this wet (I live 2km from the CBD).  This is the first year in the 6 years in Darwin I have heard one nearby.  Last year I heard one at Darwin River Dam, 50km south and maybe 1 other male around town.
Recently on my return  from holidays, I camped at Daly Waters 550km south, (as the bird flies!) from Darwin.  There were no fewer than 3 pairs in a very small area - again I stop here each time on my return in summer and have never heard one here before.
Finally I got good shots of a female!
A further sighting was made on the same trip at Pine Creek 200km south whilst searching for Hooded Parrot - another pair with a female 5 metres away from my car window at eye level!

Cheers, Rob

I am just now writing up the Eastern Koel for the Annual Bird Report.

Unlike coal, this species is going up and up and up in the ACT.

An interesting sidelight on the data is that it seems to be heading straight for the bright city lights of the Big Smoke: there are still no WOO records, for example.

Perhaps, as Jack's post suggests, when migrating they may return to their favourite places.

I’ve been following this discussion with interest as I have published my observations of adult Eastern Koel activity (association and possible interaction) around Koel fledglings for the past two seasons in CBN 39(2) 147-151 (2014) and CBN 40(2) 147-161 (2015).  Following the second paper Christine D has published an even more remarkable set of observations of adult and young Koels together in the fig trees of her garden [CBN 40(2) 162-172 (2015).
This year Koel activity in my local patch was very quiet for the first 3 weeks of 2016, when suddenly at least 5 adults moved into the area on the afternoon of 20 January and were very conspicuous by their calling and also much easier to locate than is often the case.  On 27 January I found my first Koel fledgling for this season where all this activity was first noticed and was centred, co-incidentally also within about 10 m from where I first found a fledgling last year.

PS  I would appreciate confirmation from some-one more expert on cuckoos than I am as to whether the intended recipient bird in Shorty’s photo is a juvenile or a less-barred adult Horsfield’s Bronze-Cuckoo.  The bird offering the food seems quite a bit more barred than is often the case, whereas juvenile birds often have very little if any barring.

Just after I read the recent wonderful discussion on cuckoos, I went outside and finally managed to locate the Horsfields bronze-cuckoo that's been calling here for a few days and infuriating us because we couldn't find it (we're holidaying in northern Tasmania). It was a juvenile sitting on a gate at the bottom of the garden, and it was making what I think of as begging actions - leaning forward, lowering its body and waggling its wings a little - between calls. I couldn't see a bird that these actions might have been aimed at.
We followed the bird into the paddock behind the house, where it sat on a wire fence, calling, and then we saw an adult Horsfields land next to it. The juvenile flew to the ground, caught a caterpillar, then offered it to the adult, which took it, then offered it back. The juvenile took the grub again and ate it, after whacking it a few times on the fence. Sparrows and Goldfinches both showed close attention while this was going on, landing close by on the fence, looking closely, then flying off again.
Needless to say, our enthusiastic attempts to photograph this remarkably coincidental interaction were inadequate. But we're here for another week so we may be lucky next time!

There you go then!  So the juvenile was actually being fed by, presumably, its … um … birth parent?  Great observation.

I took this pic at Campbell Park on October 17, 2015.

I wrote here my theory a couple of years ago, that cuckoos maintain a bond with their young and that they do re-unite with their young for migration.  This was after observing adult and juvenile Pallids interacting closely in the time between nesting and migration.   I may have misinterpreted when I mentioned this to Naomi Langmore, but I believe she said this is likely true.  She certainly said that adults hang around ‘their’ nests and can be heard calling regularly during the breeding period.

A few minutes ago I heard an unusual call in our garden.  I'd describe it best as a "weee-you", quite melodious in tone with a slightly rising inflection on the you.  After a little time searching I traced the call to an juvenile Fan-tailed Cuckoo, and I saw it make the call.  However a few seconds later I heard the call again from a different direction, without the juveniles bill opening.  Assuming it wasn't a very smart bit of ventriloquism I moved my search to the alternate area and found an adult Fan-tailed Cuckoo.


This somewhat surprised me as I wouldn't have expected the Masters of Delegated Brooding to display family ties and would have thought such calling back and forth to be contact prior to breeding, which is contra-indciated by:

  • the time of year; and
  • the age of the young bird.

So was the adult investing its time in a bit of cradle-snatching or was this two birds teaming up for migration?  Os something else?
