a wild bird of the empty desert and the ruined city, traditionally identified as the ostrich
The word names one particular creature, and the eight places it appears come at that creature from different angles. Two of them are plain lists of species: a bird an Israelite may not eat, sitting among other named birds. The other six are poetry, and there the bird is never only a bird. It is what you find in a place where people no longer live.
The name has an odd shape. In all eight verses the word is the second half of a fixed two-word phrase that translates literally as "daughter of" plus this word, and in the poetry the phrase is plural, "daughters of." That is not a comment on the bird's family. Several Semitic languages name animals with exactly this pattern, and Syriac uses the same construction for the ostrich, so the two words together are simply the creature's name.
What ties the uses together is less a species than a setting and a sound. Wherever the word turns up the reader is meant to picture one of these:
- open country that farming and settlement have given up on
- a city knocked down and now stocked with animals instead of people
- a cry that a grieving person can compare his own weeping to
Even the one hopeful passage keeps the setting: the animals of the waste land honor God because he has put water in the desert.
Two other Hebrew words are also read as "ostrich": the masculine form at Lamentations 4:3 (יָעֵן) and the puzzling bird of Job 39 (רְנָנִים). Whether all three name the same animal is itself argued over. What is not argued is the company this word keeps. In four of its six poetic verses it stands beside the jackal (תַּן), the other creature whose voice in an emptied place made it the standard picture of a ruined land.
