I have discussed the LTC translocation idea with Michael Anderson (using Little Barrier Island as the source). He pointed out that locating a single LTC egg is extremely difficult, let alone a group of them.

I imagine you would have to make use of new technology.
Monitor 20-30 whitehead nests with cameras and use bird recognition software to identify LTC visits.
Would also give a good indication of the level of parasitism
I don't know if there is any research (I doubt it) on whether there is a specific window of time as to when LTC eggs have to be introduced to Whitehard nests.
I imagine a first step would be to band or fit tracking devices to confirm that LTC do in fact return to their place of birth...
I think somewhere like Kapiti or Mt Bruce would be an easier option than LBI....
All in all an expensive exercise....!

I've recently finished reading Nick Davies' book on European cuckoos (can highly recommend: https://www.bloomsbury.com/uk/cuckoo-9781408856567/), which was probably the source of inspiration behind my earlier post.

In this book the author describes a number of clever tricks that he'd developed to predict where and when female cuckoos would parasitise host nests - getting to the point where he could predict both the nest in which a particular cuckoo would lay in, and on what day. Admittedly though, this work was carried out in a fen wetland (host nests were easily accessible) and a lot more is known about the breeding biology of the European cuckoo, but nonetheless they showed it was possible, albeit with a lot of time and perseverance!

Interesting discussion but not sure if anyone answered Ben's initial question. Where are the best spots for Long-tailed Cuckoo in Lower North Island? Boundary Stream is good in Hawke's Bay, but closer to Wellington, Kapiti Island is a good spot. There seem to be one or two around Upper Hutt Stokes Valley area, but the summit on Rimutaka Hill (eg walk up to the trig) is a good spot to hear them calling over summer. I have also heard them in the bush up Kapiti coast (eg Mt Wainui Whararoa farm area) and Kiriwhakapapa near Mt Bruce in the Wairarapa. Hearing them is a lot easier than seeing them.

I’ve also heard them on the Butterfly Creek Walk, Eastbourne.

I've found the McKerrow Track in the southern Remutaka FP to be a really good area for LTCs as well. Can be accessed via the Catchpool Valley, or the Sunny Grove Track in Wainuiomata.
