Here is the relevant text from Canberra from my book: "Canberra Birds: A
Report on the first 21 years of the Garden Bird Survey".

Fan-tailed Cuckoo Cacomantis flabelliformis
This is a forest and woodland inhabitant. It is less migratory than other
cuckoos, so its monthly pattern, although typical of cuckoos, is much less
well-defined. This species is quite vocal, especially during spring. However
the call is probably not as far-carrying as Pallid or Brush Cuckoo. From a
mid winter low with very few observations, numbers increase sharply from
August to a peak in October, then decline quickly till December, staying in
even reduced numbers through summer and autumn before declining to the
winter low. Numbers have declined significantly, at about half the abundance
from Years 12 to 21 as for the first 11 years.

hi Sonja,
I reckon that's the case with most migratory species in Australia in that
some small proportion of the populations don't make their annual migrations
& do stay to "over-winter"...
I've been sceptical for many years as to whether Australian Black-winged
Monarchs are migratory - even though I saw an adult near Cooktown at my
study site in June 2012, i'm now convinced that the Auat population is
indeed migratory, but that some number of individuals remain here to

i'm certain there are countless other examples of this in other species as
well, no doubt...
