Mark G sent in images of the Thick-billed Green Pigeons (Treron curvirostra) (male above, female below) feasting on the figs of Ficus benjamina or Benjamin fig, also known as waringin. The tree stands near the canteen of the MacRitchie Reservoir Park and the picture was taken at 5.30 pm.
Fig trees, when in fruits, attract large numbers of birds, all coming to feast on the succulent figs. Waringin is a common strangling fig that attaches itself on our wayside trees. In time the aerial roots grow round the trunk of the host tree and with the years, the thickening of the roots prevents the host tree from increasing in girth. This in turn causes the death of the host tree.
Because of the “strangling” nature of this fig and its invasive roots, its presence on our wayside trees is frowned upon. Our wayside trees are thus “rescued” and as a result we do not see many such strangling figs around. However, old stranglers are left alone and thus when such trees are in figs, we tend to “hear” the trees long before we actually see them, such is the popularity of the figs with birds.
