נֶשֶׁר (nesher) — griffon vulture; formerly eagle

Etymology

The biblical נֶשֶׁר appears 27 times and is described by contextual clues that point clearly to the griffon vulture (Gyps fulvus): it is bald-headed ("הַרְחִיבִי קָרְחָתֵךְ כַּנֶּשֶׁר," Micah 1:16), nests on rocky cliffs ("סֶלַע יִשְׁכֹּן," Job 39:28), and feeds on carcasses ("וּבַאֲשֶׁר חֲלָלִים שָׁם הוּא," Job 39:30). These traits match the griffon vulture, not the eagle.

Yet the earliest translation of the Bible into another language, the Septuagint (Greek, 3rd–2nd century BCE), consistently renders נֶשֶׁר with the Greek word ἀετός (aetos), meaning eagle. This choice had enormous downstream consequences. The Talmud reflects the same identification: in Sanhedrin (12a), a Roman legion is called a נֶשֶׁר after the eagle embossed on soldiers' shields. Medieval scholarship and all subsequent European-language Bible translations followed this convention. The Hebrew grammarian and lexicographer tradition from the Middle Ages onward aligned rabbinical usage with eagle, and leading textbooks of the Haskalah (Baruch Linda's Reshit Limudim, 1788; Mendele Mocher Sfarim's Toldot HaTeva, 1866) and Ben-Yehuda's dictionary maintained the eagle identification well into the twentieth century.

The correction came from the Reverend Henry Tristram, who argued in 1867 on the basis of biblical contextual clues that the נֶשֶׁר must be the vulture. Israeli zoologist Israel Aharoni followed this reasoning in his 1923 textbook Torat HaChai, reassigning נֶשֶׁר to the griffon vulture and calling the eagle עַיִט — a biblical term for a group of raptors — based on a false folk etymology connecting עַיִט to Greek aetos. Aharoni's taxonomy spread through the educational and zoological establishment.

The Hebrew Language Academy resisted for decades. In the summer of 1964, a subcommittee proposal to formalize Aharoni's usage was voted down; the bird-name dictionary published that year simply omitted the entry. In 1972, zoologists again tried and again failed to get the Academy to ratify their standard usage, with members insisting that a two-thousand-year tradition could not be overturned by fiat. Academy vice president Zeev Ben-Hayyim predicted the zoologists would ultimately accept the Academy's ruling. They did not.

In autumn 1973, in the very first session of his new presidency, Ben-Hayyim — now on the other side — announced a "compromise": the vulture would be called נֶשֶׁר and the most common eagle would be called עֵיט נִשְׁרִי ("eagle-like raptor"). He explained the reversal: "The Zoological Society threatened to petition the High Court of Justice," and he feared the irreversible damage such a case would cause the institution. A heated vote ended in a 7–7 tie; Ben-Hayyim exercised his presidential double vote to break the tie and close the matter.
