This mitzvah requires us to examine and distinguish between kosher and non-kosher birds. Unlike animals, the Torah does not give specific physical signs for birds but instead lists non-kosher species. The Sages derived general traits of kosher birds, such as not being predators. By learning and transmitting these distinctions, we maintain the sanctity of our diet and fulfill the Torah’s command to separate the pure from the impure.

Commentary & Classical Explanation:

• Rambam (Hilchot Ma’achalot Asurot 1:14): Rules that kosher fowl are identified by tradition, and if a community has a clear tradition that a species is kosher, it may be eaten.
• Sefer HaChinuch (Mitzvah 154): The root is to cultivate holiness through awareness of what we eat, separating Israel from the practices of other nations.
• Talmud (Chullin 61a): Explains that kosher birds can be identified through tradition and by signs such as non-predatory behavior and possession of an extra toe, crop, and peelable gizzard.
