How do birds nest and lay eggs in trees in spring?

I think you can send a lovely bird, hoping that they will grow up quickly and give whatever they want to express their feelings.

Birds nest on balconies, windowsills, aisles and eaves of human activities. Some birds fly back to breed and hatch every year, and some even get along with people with "feelings" and provide "wake-up service" on time every day.

"Birds are very vigilant. Some species will have a stress reaction to human close activities, and parents will even abandon their nests. " Remind the public that it is necessary to care for birds scientifically and keep their distance undisturbed, so that human beings and wild animals can be more harmonious.
