Geoffrey, very interesting, do you know where they
The reason I ask is that Pied Currawongs used to
pass over my place in Chapman during the mid autumn to early
spring period in large numbers, sometimes up to 200 birds and often over a
short say 15 minute period. They used to fly W very noisily towards
Woden/Mt Taylor in the morning shortly after or even before sunrise, and return
late afternoon, usually a bit more strung out. One time I checked and
found them coming out of the former pine forest at Narrabundah Hill as it
was only just getting light.
Since the fires in January 2003 this phenomenon
seems to have completely gone, indeed it had already diminished significantly
for a few years before that when they seemed to take a more
northerly path through Rivett.
The very noticeable roost flight of the Australian
King Parrot to the same pine forest/Mt Stromlo, particularly in
winter, also no longer occurs.
