Stork

Heb. hasidah, meaning "kindness," indicating thus the character
of the bird, which is noted for its affection for its young. It
is in the list of birds forbidden to be eaten by the Levitical
law (Lev. 11:19; Deut. 14:18). It is like the crane, but larger
in size. Two species are found in Israel, the white, which
are dispersed in pairs over the whole country; and the black,
which live in marshy places and in great flocks. They migrate to
Israel periodically (about the 22nd of March). Jeremiah
alludes to this (Jer. 8:7). At the appointed time they return
with unerring sagacity to their old haunts, and re-occupy their
old nests. "There is a well-authenticated account of the
devotion of a stork which, at the burning of the town of Delft,
after repeated and unsuccessful attempts to carry off her young,
chose rather to remain and perish with them than leave them to
their fate. Well might the Romans call it the pia avis!"

In Job 39:13 (A.V.), instead of the expression "or wings and
feathers unto the ostrich" (marg., "the feathers of the stork
and ostrich"), the Revised Version has "are her pinions and
feathers kindly" (marg., instead of "kindly," reads "like the
stork's"). The object of this somewhat obscure verse seems to be
to point out a contrast between the stork, as distinguished for
her affection for her young, and the ostrich, as distinguished
for her indifference.

Zechariah (5:9) alludes to the beauty and power of the stork's
wings.
