Just Think About How Male Birds Start Making Their Nest?

I was looking through an article about birds and came across how weaver birds took so much trouble to start building their nest.

Make objective is to attract a female bird to be his life partner.

Have a look at this marvellous video clip:



The lesson from this nest making exercise is to focus on the purpose of building a nest.

I think the same applies to swiftlet birds.

The male will start the building operation and after reaching a level that is appropriate he will invite his partner to check for her approval.

Only if she approved he will be able to continue plus at the same time make love to her.

Remember once copulation is successful she has eight days to lay the first egg.

The second will be either on the ninth or tenth day.
