The YTBCs which were the highlight of the Percival Hill walk last Saturday (19th) have returned to the same spot several mornings this week.
They exhibited again the remarkable behaviour which so intrigued us last Saturday. The flock of about 35 Cockatoos flies around as quite a tight group and twice this week I have seen them very high up, wheeling and separating and regathering above Percival
Hill. Then they come down and perch in the trees just beyond the concrete crossing (which as I have noted before, has created a popular shallow drinking place for many different birds). They fly down to the crossing and to the reed bed just upstream of it.
Those at the crossing drink from it and some bathe vigorously. A larger number seem to prefer the reeds. They land relatively clumsily in the reeds and then, clinging to a single reed, they climb headfirst down the reed stalk until they reach the bottom
and can drink from there.
We were privileged to see them on theCOG walk but I cannot guarantee the show on a given day. I did not see them there this morning but the fog did not lift until late.
