I love this! Great pictures too.
Baya Weavers (Ploceus philippinus) constructing their nest.
The male bird usually builds the nest half way, up to the so-called helmet stage
that consists of partly of the living chamber.
He then tries to get his mate to be interested in the half-built nest.
Once he has her approval, he will continue with the construction,
completing it with a tube-like structure below the entrance.
Sadly, if the female is not happy with the nest
the male has to break it up and start again.
She has to feel it is safe and water proof.
