Deuteronomy 22:6-7

6“If you happen to come upon a bird’s nest along the road, in any tree or on the ground, with young ones or eggs, and the mother [bird] is sitting on the young or on the eggs, you shall not take the mother with the young.

7You shall certainly let the mother go, but you may take the young for yourself, so that it may be well with you and that you may prolong your days.
