ספורנו — שלח תשלח את האם / למען ייטב לך

Q — Why does שילוח הקן — a seemingly minor procedural mitzvah — earn the same reward as כיבוד אב ואם — אריכות ימים? What is so weighty about sending away a mother bird?

A — For Sforno, the disproportion vanishes once you see what the mitzvah is structurally doing. The wild birds whose eggs are taken are הפקר — communal property, available to anyone. Hunting the mother along with the eggs (or chicks) would deplete the wild bird population — to everyone's loss. Sending away the mother preserves her egg-laying capacity for future seasons. So even this minor ritual contains a quiet act of gemilus chasadim toward an unnamed public — a small but real chesed "להמון." That's the Torah's chiddush about reward: "אפילו בזה הקצת של גמילות חסדים יהיה אוכל פירות בעולם הזה והקרן קיימת לעולם הבא." Reward isn't proportional to the ritual complexity of a mitzvah, but to the chesed embedded in it.
