This morning my thermometer read -3 celcius. Yesterday afternoon a
horsfield's bronze-cuckoo was calling from a tree (Riverland, SA).

However, my point concerned Black-eared Cuckoo not all cuckoos in general.
Black-eared Cuckoos are fairly regularly recorded in some southern areas in
Victoria but I don't recall (off the top of my head - and this may reflect a
lack of research) records of this species so early in the year. Therefore,
my hypothesis is that it is indeed an unusual mid-winter sighting for this
particular species that is otherwise rather infrequently encountered on the
perimeters of its range. I suggest that this record is indicative of the
barmy/balmy weather we've been experiencing lately!
