The Pigeon-snaring Mounds Of Tonga

In North America, the industrious Mound-builders excavated untold millions of basketfuls of soil which they piled up in impressive mounds. Flat-topped Monk's Mound at Cahokia, Illinois, rivals the Great Pyramid in volume. A casual observer of this huge earthen structure could only conclude that such immense labor was undertaken for some social imperative, such as worship or sacrifice. Perhaps this was the case in North America, but deep in the South Pacific, just east of Fiji, on the islands of Tonga, native peoples scraped large mounds of earth for what seems to be a frivolous purpose: pigeon-snaring!

But bear in mind that carnivory on these romantic Pacific islands was difficult because large game animals were nonexistent. Captured enemies helped solve the protein problem, but pigeons were much more common, and some species were good-sized and delicious. So much so that eventually only island royalty was allowed to catch and eat them. Pigeon poachers were whipped or executed (and maybe eaten?) In fact, pigeon snaring became a royal sport. To this end, starting at least a thousand years ago, the king's loyal subjects grubbed up the thin island soil and piled it up into high mounds.

Tonga's pigeon-snaring mounds did not compete with Monk's Mound sizewise, being at most 115 feet in diameter and perhaps 15 feet high. But that's still a lot of dirt. On the tops of the mounds were smaller, beehive-shaped mounds with vertical slits in them large enough to conceal a human. From these blinds, the king and princes would swing nets on the ends of 12-foot poles to catch pigeons.

Of course, no self-respecting wild pigeon would ever fly over such a suspicious hill without some enticements. So, captive pigeons caged on the mound were set to cooing and other pigeons tethered by long strings were launched. Sure enough, wild pigeons were lured close enough to be snared.

Comment. Now let's see, in the heyday of the Moundbuilders, the North American skies were darkened by flocks of Passenger Pigeons. Hmmm!

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
