Pink-necked Green-pigeon Expels Indigestable Seed

“A Pink-necked Green-pigeon (Treron vernans) that landed in a Yellow Saraca (Saraca thaipingensis) attracted my attention. It is a normal behaviour of such pigeon to remain in the same perch for long periods without much apparent activities. After locating it in the viewfinder of my camera, I had the luxury of time to move around to get the best view. In the end I settled for a back side view of the bird instead of a side view as it would require me to stand right in the middle of our estate road causing inconvenience to others and risking myself.

“As expected, other then seeing the bird looking out for danger (from me included), nothing much interesting was observed, not even the usual fanning of it’s tail.

“However, after some time, an object was expelled from the vent following the tell-tale sign of lower body part movements. On review of the video recording, the object appeared to be a round undigested seed, which could be that of one of the fan palm species or Sea Apple (Syzygium grande). There were a few more contractions of the vent following the expulsion of the seed. These contractions were similarly observed in Oriental Magpie-robin (Copsychus saularis) LINK.

“Below is the link to the edited short video clip, recorded in the morning of 13 May 2014. It includes a replay at half speed.”
