When you see the swallow fall from the nest, pick it up and put it back in the nest. Pay attention to the power in your hands. After all, swallows are fragile. Many times, swallows fall for many reasons, such as parasite bites, extreme heat, illness, hunger, flying away from the nest, accidental slipping and so on. If the swallow falls to the ground and cannot fly back to the nest, it needs artificial assistance.

Don't pick up a swallow when it falls;

1, don't pick up the swallow when it falls, because the mother of the swallow is xenophobic. Swallow's taboo is that other animals have touched his cubs. If the cubs are infected with the smell of other animals, then the mother swallow may abandon the little swallow.

2. When a swallow sees a man put his child back in its nest, it will drop the nest and fly away without the child. Because if swallows smell other smells, they will deliberately push swallows down and die, and some even push the whole nest of swallows down and die. However, this statement has not been scientifically proved.
