Birds are part of intelligent animals not to be ignored and as a result of their lifestyle, they have gained so much attention from wildlife researchers and other scholars.
They are one of the animals that will not settle for a second best and thereby not breed in the same nest twice. They could decide to rebuild it or add some other things on top of the nest in order to get rid of the aged look, more comfortable for breeding their chicks in which they have their own way of carrying out the work.
Before birds use a nest, they ensure to clean up the place and give it a good look just like you would do to give an apartment a different look from what it used to be. And as part of the breeding process of birds, they will only settle or raise their young ones in an area where both the bird and her brood are free from predators and disease.
Birds do not want to waste their effort trying to set up a new nest so they will prefer to return to the same area where their old nest is and raise broods but they don’t just return so their old nest can be reused, they add nesting material on top of the deteriorating one each time of the year they are ready to breed so that the old material acts more like the foundation of the new nest.
