Episode Details

There is a dispute between Rav Nachman and Ameimar whether a bird possessing a single sign can be permitted if one is not expert in identifying the peres and ozniyah. Rav Nachman does not permit it, but Ameimar rules that any bird with a single sign is permitted, provided it is not known to be a predator (doreis), as there is no concern regarding the peres and ozniyah since they do not inhabit populated areas.

The characteristics of specific birds are defined, such as the white swallow (concerning which Rabbi Eliezer and the Sages disagree) and the sacrificial eligibility of birds like the tasil—which is valid before its maturity as a young dove (ben yona), but invalid if it has already reached maturity as a turtledove (tor).

Rav Asi enumerates eight birds whose status remains in doubt ("eight doubts") because their gizzards do not peel easily by hand but only with a knife. A series of short Amoraic traditions is presented, identifying various birds as forbidden or permitted and providing mnemonic signs to remember which of them are forbidden.
