Avian Nesting 13/100 in October 2017 - Pin-tailed Parrotfinch

In late October 2017  I witness a single parent (male)  preparing a nest in Sg Congkak. The female was not seen for the two hour I spend monitoring its activity. The bird come in quite regularly 15-30 minutes interval in the morning but during noon  it kept away. I left at about 1.30pm

The nest looks like a broadbill hanging clump of messy  twigs and straws weaved to a living vine. The nest is about 30ft high up above a stream. Across the stream there is a hugh bamboo grove to which it presumably  feed on its seeds.

I have always thought its nest would be in a trunk hollow like the parakeet.

Last visit in last week of October there was no activity around the nest. Was it abandoned or damaged by inclement  weather.............
