“On 1st June 2016, I went to Upper Seletar reservoir, Track 7 to observe Red-crowned Barbets (Megalaima rafflesii) feeding on the solitary Canthium glabrum or Green Coffee tree which was approximately about 5 meters tall.
“This tree had an abundant supply of fruits (top) that hung down like clusters of grapes. The birds would easily slice the fruits with their powerful beaks and feed on the greenish flesh (above). I also observed a bird tossing the fruit and swallowing it (below) which I assumed it had already removed the angular seed that looks like an arrow-head.
“I went to this place several times and my last visit was on 6 Jul 16 which was more than a month after my first visit. By this time, the amount of fruits have been greatly reduced (below) which I reckoned would last for another 4 days. I was surprised that the fruits of the Canthium glabrum (Green Coffee) tree could last for more than a month.”
