If a bird’s nest should chance to be before you in the way, 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 bird with the young. You shall surely let the mother bird go, and take only the young, that it may be well with you and that you may prolong your days. (Deuteronomy 22:6-7 AMP)
