Over the last few weeks several Galahs have been hanging around a hollow in one of our mallee trees near our house. This is the largest tree on our property and is probably well over a hundred years old-maybe several hundred. Only mature age mallee trees have trunks the size of this one. And only mature mallee trees develop branches large enough to create hollows.
Over recent years this hollow hosted a wild bee colony, but that seems to have moved on. Over the last two to three years Galahs have investigated this hollow on many occasions but none has nested in it. One pair even diligently went about enlarging the hollow but with no nesting taking place.
I can’t be sure whether this is the same pair or a new pair trying it on for size. They certainly seem very interested and hang around there off and on for several hours every day. They even chase off other interested tenants, so they must be quite serious about it.
I’ll keep you posted on any developments on the home front.
