   cristatus, or Vanellus vanellus). It has long and broad
   wings, and is noted for its rapid, irregular fight, upwards,
   downwards, and in circles. Its back is coppery or greenish
   bronze. Its eggs are the "plover's eggs" of the London
   market, esteemed a delicacy. It is called also peewit,
   dastard plover, and wype. The gray lapwing is the
   Squatarola cinerea.

Easton's 1897 Bible Dictionary:

Lapwing
   the name of an unclean bird, mentioned only in Lev. 11:19 and
   Deut. 14:18. The Hebrew name of this bird, _dukiphath_, has been
   generally regarded as denoting the hoope (Upupa epops), an
   onomatopoetic word derived from the cry of the bird, which
   resembles the word "hoop;" a bird not uncommon in Palestine.
   Others identify it with the English peewit.
