• Between September and December, one to five eggs are laid at daily intervals. Incubation lasts 13 to 17 days, starting with the second or third egg and is primarily carried out by the female.

Why do birds make nests before laying eggs?

• To protect their nests from predators, many bird species hide their nests.

• Some species may select inaccessible nesting sites or construct the nest in such a way as to deter predators. 

• Bird nests can also serve as a habitat for other inquiline species, which may or may not be harmful to the bird.
