For those interested and without access to Nature,
Naomi Langmore has the paper on the web at:

They suggest that begging calls in Horsfield's bronze-cuckoos have
evolved to be similar to Superb Fairy-wrens.  I'm not sure how they
exclude learning by the cuckoo fledgings.  They are uncertain whether
wrens learn to recognise wren chicks versus cuckoos.  There is quite a
bit more in the paper which is well worth the read.
