A Three-Part Study

The Specimens

The Torah's list of forbidden birds, organized as twenty head-terms plus four family-expansion clauses (למינה / למינו / למינהו) — 24 rows total, matching the Talmudic count of 24 forbidden birds.

The Torah names twenty distinct birds — or twenty-one, if ראה/דאה and איה/דיה are counted as separate lexical entries. The Talmud reaches twenty-four; this document renders the four למינה/למינו/למינהו clauses as structural rows to match that count. The Gemara's own derivation of the count is more complex than a one-to-one clause-to-row mapping.

Row 1 נֶשֶׁר nesher griffon vulture (mod.) / eagle (trad.) Talmudic-anchored
Verse
אֶת־הַנֶּשֶׁר וְאֶת־הַפֶּרֶס וְאֵת הָעׇזְנִיָּה׃

This passage establishes the structural count (24 birds, 4 signs) and groups נשר · פרס · עזניה. It is rendered once here and cross-referenced from the peres and ozniyah rows.
Modern Candidate
Gyps fulvus (Eurasian griffon vulture). Common modern candidate; no medieval לעז or Rambam PM anchor in this dataset.

Leviticus 11:13 · Deuteronomy 14:12
Chullin 61b names פרס as one of the two birds having exactly one of the four signs. See the verbatim 61b quote on the nesher row above.

Leviticus 11:13 · Deuteronomy 14:12
Chullin 61b names עזניה as the other bird with exactly one of the four signs. See the verbatim 61b quote on the nesher row above.
Modern Candidate
Unresolved. Aegypius monachus (cinereous vulture) is the common modern candidate but carries no medieval לעז or Rambam PM anchor in this dataset.

Row 6 עֹרֵב orev raven (base term) Talmudic-anchored
Verse
אֵת כׇּל־עֹרֵב לְמִינוֹ׃
Leviticus 11:15 · Deuteronomy 14:14
Talmud · Chullin 63a ("black as a raven")
אָמַר מָר: עוֹרֵב זֶה עוֹרֵב. אַטּוּ קַמַּן קָאֵי? אֶלָּא אֵימָא עוֹרֵב זֶה עוֹרֵב אוּכְמָא. וְכֵן הוּא אוֹמֵר: קְוֻצּוֹתָיו תַּלְתַּלִּים שְׁחֹרוֹת כָּעוֹרֵב (שיר השירים ה, יא).
The sub-kinds expansion (למינו) is on the orev family row below.
Modern Candidate
Corvus spp. (raven and related corvids). The Torah itself presents a family group with למינו, so family-level identification is secure; species-level is not.

Row 10 נֵץ netz hawk / sparrowhawk Anchored (Rashi + Talmud)
Verse
וְאֶת־הַנֵּץ לְמִינֵהוּ׃
Leviticus 11:16 · Deuteronomy 14:15
Rashi on Leviticus 11:16
לעז: אשפר״ויר esprevier — sparrowhawk / small hawk
Talmud · Chullin 63a (Abaye on netz sub-kind)
תָּנוּ רַבָּנַן: הַנֵּץ — זֶה הַנֵּץ. לְמִינֵהוּ — לְהָבִיא אֶת בַּר חִירְיָא. מַאי בַּר חִירְיָא? אָמַר אַבַּיֵי: שׁוּרִינְקָא.
Modern Candidate
Accipiter sp.; likely Accipiter nisus (Eurasian sparrowhawk). Rashi's esprevier and the Talmudic sub-kind both point to the accipiter-class hawk zone; species-level identification is less secure.

Row 11 כּוֹס kos owl (paired with yanshuf in Rashi) Rashi-anchored (with caveat)
Verse
וְאֶת־הַכּוֹס וְאֶת־הַשָּׁלָךְ וְאֶת־הַיַּנְשׁוּף׃
Leviticus 11:17 · Deuteronomy 14:16
Rashi on Leviticus 11:17 (owl-pair)
לעז: צואי״טש · יי״בו chouette · hibou — owl (pair)
Rashi gives two Old French owl-words (chouette, hibou) covering כוס and ינשוף together as an owl-pair. The internal one-to-one assignment — which French word belongs to which Hebrew word — is not made explicit in Rashi. This row should not be read as assigning chouette specifically to כוס.
Modern Candidate
Owl group (Strigidae/Tyto indeterminate). Rashi's לעז anchors the owl zone; internal species allocation between kos and yanshuf is not Rashi's own.

Row 12 שָׁלָךְ shalach fish-catching bird (unresolved species) Talmudic-anchored
Verse
וְאֶת־הַשָּׁלָךְ וְאֶת־הַיַּנְשׁוּף׃
Leviticus 11:17 · Deuteronomy 14:17
Rashi on Leviticus 11:17 (behavioral, no לעז)
זֶה הַשּׁוֹלֶה דָּגִים מִן הַיָּם.
Rashi gives a behavioral definition — "this is the one who draws fish from the sea" — not an Old French gloss. Behavior anchors ecology, not taxonomy.
Talmud · Chullin 63a (Rav Yehuda, matching Rashi's phrasing)
אָמַר רַב יְהוּדָה: שָׁלָךְ — זֶה הַשּׁוֹלֶה דָּגִים מִן הַיָּם.
Modern Candidate
Fish-snatching water bird, species unresolved. The medieval witnesses narrow ecology, not species.

Row 13 יַנְשׁוּף yanshuf owl (paired with kos in Rashi) Rashi-anchored (with caveat)
Verse
וְאֶת־הַיַּנְשׁוּף וְאֶת־הַתִּנְשֶׁמֶת
Leviticus 11:17–18 · Deuteronomy 14:16
Rashi on Leviticus 11:17 (owl-pair, shared with kos)
לעז: צואי״טש · יי״בו chouette · hibou — owl (pair)
Same owl-pair as on the kos row. Rashi's two Old French owl-words are not individually allocated — which French word belongs to יַנְשׁוּף as distinct from כּוֹס is not stated by Rashi himself.
Modern Candidate
Owl group, unresolved at species level.

Row 14 תִּנְשֶׁמֶת tinshemet Rashi's לעז: bat (unresolved zoological problem) Rashi-anchored (with caveat)
Verse
וְאֶת־הַתִּנְשֶׁמֶת וְהַקָּאָת וְהָרָחָם׃
Leviticus 11:18 · Deuteronomy 14:16
Rashi on Leviticus 11:18
לעז: קלב״א שוריץ calve soriz (chauve-souris) — bat
Rashi's לעז is a strong lexical datum but creates an unresolved zoological problem: it points to "bat," yet the Torah separately lists עטלף as its own bird on the very next verse (Leviticus 11:19 — see atalef below). The לעז is therefore a lexical anchor, not a solved identification.
Modern Candidate
Unresolved. Rashi's reading and the Torah's separate listing of עטלף are in tension.

Row 15 קָאָת ka'at unresolved (Gemara: קוק, unidentified) Talmudic-anchored
Verse
וְהַקָּאָת וְהָרָחָם
Leviticus 11:18 · Deuteronomy 14:17
Talmud · Chullin 63a (Rav Yehuda)
אָמַר רַב יְהוּדָה: קָאָת — זוֹ הַקּוּק.
Modern Candidate
Unresolved. The Gemara identifies קאת with an Aramaic term קוק which is itself not further identified in this passage.

Row 16 רָחָם racham Gemara: שרקרק (unidentified) Talmudic-anchored
Verse
וְהָרָחָם וְהַחֲסִידָה
Leviticus 11:18 · Deuteronomy 14:17
Talmud · Chullin 63a (R. Yochanan on mercy etymology)
רָחָם — זוֹ שְׁרַקְרַק. אָמַר רַבִּי יוֹחָנָן: לָמָּה נִקְרָא שְׁמוֹ רָחָם? כֵּיוָן שֶׁבָּא רָחָם בָּאוּ רַחֲמִים לָעוֹלָם.
Talmud · Chullin 63a (Rav Bibi bar Abaye on the messianic sign)
אָמַר רַב בִּיבִי בַּר אַבַּיֵי: וְהוּא דְיָתֵיב אַמִּידֵי וְעָבֵיד שְׁרַקְרַק. וּגְמִירִי דְּאִי יָתֵיב אַאַרְעָא וְשָׁרֵיק — אֲתָא מְשִׁיחָא, שֶׁנֶּאֱמַר: אֶשְׁרְקָה לָהֶם וַאֲקַבְּצֵם (זכריה י, ח).
Modern Candidate
Unresolved. Modern Hebrew uses רחם for Neophron percnopterus (Egyptian vulture) but this is a later identification; the Talmudic שרקרק is not itself securely identified.

Row 17 חֲסִידָה chasidah stork (via Rashi's לעז) Anchored (Rashi + Talmud)
Verse
וְהַחֲסִידָה וְהָאֲנָפָה לְמִינָהּ
Leviticus 11:19 · Deuteronomy 14:18
Rashi on Leviticus 11:19
לעז: ציגוני״א cigogne — stork
Talmud · Chullin 63a (Rav Yehuda)
אָמַר רַב יְהוּדָה: הַחֲסִידָה — זוֹ דַּיָּה לְבָנָה. לָמָּה נִקְרָא שְׁמָהּ חֲסִידָה? שֶׁעוֹשָׂה חֲסִידוּת עִם חַבְרוֹתֶיהָ.
Modern Candidate
Ciconia ciconia (white stork). Family-level "stork" is anchored by Rashi's cigogne; species-level white stork is the common Levantine candidate, though species precision still requires caution.

Row 18 אֲנָפָה anafah heron (via Rashi's לעז) Anchored (Rashi + Talmud)
Verse
וְהָאֲנָפָה לְמִינָהּ וְהַדּוּכִיפַת וְהָעֲטַלֵּף׃
Leviticus 11:19 · Deuteronomy 14:18
Rashi on Leviticus 11:19
לעז: הירו״ן heron — heron
Talmud · Chullin 63a (Rav Yehuda)
הָאֲנָפָה — זוֹ דַּיָּה רַגְזָנִית. לָמָּה נִקְרָא שְׁמָהּ אֲנָפָה? שֶׁמְּנָאֶפֶת עִם חַבְרוֹתֶיהָ.
Modern Candidate
Ardea sp.; probably Ardea cinerea (grey heron). Rashi's heron anchors the family; species-level is slightly less secure.

Row 19 דּוּכִיפַת duchifat hoopoe Anchored (Rashi + Talmud)
Verse
וְהַדּוּכִיפַת וְהָעֲטַלֵּף
Leviticus 11:19 · Deuteronomy 14:18
Rashi on Leviticus 11:19
לעז: הרופ״א huppe (likely) — hoopoe
Talmud · Chullin 63a (Rav Yehuda)
אָמַר רַב יְהוּדָה: דּוּכִיפַת — שֶׁהוֹדוֹ כָּפוּת. תַּנְיָא נַמֵי הָכִי: דּוּכִיפַת שֶׁהוֹדוֹ כָּפוּת, וְזֶהוּ שֶׁהֵבִיא שָׁמִיר לְבֵית הַמִּקְדָּשׁ.
Modern Candidate
Upupa epops (hoopoe). Rashi's huppe and the Talmudic "glory-bound" (crest) etymology both point to a crested bird; this is the most widely accepted identification on the list.

Bat (at the lemma level). No Rashi לעז on עטלף itself — Rashi's bat-word appears on tinshemet (Row 14) and the conflict between the two listings is noted there. No verified Talmudic etymology for עטלף in this dataset.
