I have been out picking a dish of ripe Mulberries (Morus spp.) in Judy's front garden. They look delicious. In fact the Mulberries on the tree are "left-overs" - the ones the Currawongs (Strepera graculina ) could not eat. Fortunately there are enough to go around. I guess that says something about Nature's bounty.
Judy's tree is only young, but I know they can grow to be very large. At this stage I can pick the fruit from most of the branches, which is good. We need to decide whether to prune the tree for future years, or just let it grow up, and provide more feed for the Currawongs. Not that Currawongs need any encouragement.
When I was growing up in Canberra (from 1959 onwards), Currawongs were regular winter visitors. They were described as "vertical migrants" - that is they came down from the mountains behind Canberra in winter, to feed on the abundant berries and other fruit which Canberra people grew (conveniently for the Currawongs). However, they did not breed in Canberra at that stage, as they like really tall treees as nest sites. Now that the trees in Canberra's gardens and parks are more developed, they breed in town, which is bad news for the resident small birds, such as the Blue Wrens, and Thornbills.
Currawongs mostly eat berries and fruit in Autumn and Winter. In Spring and early Summer, when they are feeding their young, they change their diet to a higher protein intake. They raise their young on insects, worms, and also eggs and nestlings of small birds. Hence, they are generally unpopular birds with Canberra'a bird watchers.
Should I suggested that Judy chop down her Mulberry tree? I don't think so!
