What is this flying creature at MacRitchie Reservoir? It has a triangular flap on its butt

Submitted by Stomper Crystal

Stomper Crystal came across a peculiar looking creature at MacRitchie Reservoir two weeks ago.

In an email and telephone interview, the Stomper said that the creature was flying around before it landed on a tree.

It then started climbing upwards.

In a video the Stomper sent, the creature appeared have a triangular flap on its butt.

Crystal estimates that the creature was the size of a lemur.

She did not manage to get a good look at its face because it was too dark.
