Drunken Javan Mynas!
Many years ago now, I lived in a house with a large garden. Next to the house was an old Madras Thorn (Pithecellobium dulce) tree which spread its branches to within a few feet of the walls. This tree flowered and produced fruit on a fairly regular basis but as far as I know this was not edible. At least I never tried to do so and perhaps this was wise. The fruit would on occasions fall to the ground during the day, after the gardener had swept up what had fallen overnight. It seems that some, if not all, of this was overripe and in some cases had even begun to ferment.
On many occasions I would come home from the office in the evening and find Javan Mynas (Acridotheres javanicus) on the verandah apparently dead to the world while others were staggering around tipsily having indulged a little too heavily in the overripe fruit. I took no notice of them nor they of me. By the morning they would all have disappeared, presumably with monumental hangovers.
Sadly for the mynas the tree had eventually to be cut down because the roots were causing trouble and furthermore it was infested with large millipedes which appeared to eat the layer under the bark, causing it to peel off and this eventually killed some of the big branches.

Additional comment by Nature Consultant, R Subaraj
Richard's article is most interesting. We have long known that butterflies get rather tipsy drinking from fermented fruits and this can be viewed easily in captive collections at any butterfly farm. They are so stoned that you can place your finger under their legs and they will crawl onto them.
In many areas, particularly forested habitats, various birds and other animals feed on the fallen fruits lying on the ground below many a tree. Some of these fruits are obviously rotting and fermenting. One wonders whether these have a similar effect on other species. It would be great to receive feedback from anyone who has witnessed any similar disorientated behaviour.
Additionally, has anyone else seen anything feeding on the fruits of the Madras Thorn? This tree used to be a common sight around Singapore when I was growing up but nowadays, they are rather uncommon.
