Hi Denis, Julian, Geoffrey et al,
I remember seeing a Galah in the fork of a Red
Spotted gum and chewing the bark in the park one door away from my place
when I was building my house around 1970. The exposed wood was fresh and there
was no hole there. I wondered if a hole might develop there and looked
at it from time to time over the next few years. The Galah(s)
kept on chewing the regenerating edge of the bark within reach of the
fork. Today there is a hole in that fork and I have seen a Galah go
in. I have no idea if it was the same Galah and doubt
whether it/they did it with the aim of creating a hollow. More
likely they do it out of boredom while resting or to sharpen/wear their
beak and in some cases a hole will develop there after a few decades if the bark
is prevented from growing over the scar.
I suspect that Galah numbers have increased in the
ACT area since settlement if there were any here to start with and they do a lot
more damage to trees than they used to. Have they? Does anyone know? I
remember seeing the first Galahs in Tidbinbilla Nature Reserve after I
worked there for about 5 years ca 1981 and think they had just arrived
there. i e there were none in the Tidbinbilla area before.
Cheers
Peter Ormay
