Yellow tailed black cockatoos

[Rob Geraghty <>]

FWIW I have worked on Gladstone street near Tennant Street for about eight years and have never seen a Black Cockatoo here. However, I assume that the area where you saw them was near Domayne, where there's a row of large conifers. That is some distance from where I work, and there could easily have been flocks of birds there which never came this way. I often pass those trees when driving to and from work and at lunch time.

In mid 2003 when I worked on Tennant street Fyshwick, there were often
many. Some may recall following the bushfire, we had lots of them in
Canberra. I had them flying over my house on that night on 18 January. The
biggest count I got was from that Fyshwick site I think about 500 within
probably 3 to 5 hectares. That was based on seeing multiple flocks of 50
to 100 YTBC flying into the trees and having about that small proportion
of change on those already there.  As big flocks comprising part of this
mass passed more or less over the office and paddocks between tennant st
and the airport I think I recorded 350 as the number for the GBS that I
was doing for the site that year.

I observe small flocks from time to time over the inner south: on
Wednesday
for example, 5 flying over Woden northwards around 4.45pm.

Often also down nr Scrivener Dam.

A few weeks ago in the early morning I saw a single YTBC flying over
Curtin
shops to the south east quite fast and calling querulously. I guess it got
left behind.
