- 1990 September, “Cymry yn y diffeithwch”, in Eco'r Wyddfa‎^[1], volume 160, page 16:
  Nid oedd yr ymsefydlwyr cynnar wedi gweld dim byd tebyg i beth o'r bywyd gwyllt a welsant yno--heidiau o bengwiniaid ac eliffantod y môr ar hyd yr arfordir, gyrroedd o guanacos tebyg i lamas yn crwydro'r gwastadeddau, armellogion a drewfilod, ysgyfarnogod Patagonia a enwyd ganddynt yn ‘sgwarnogod y paith’ a'r rhea bychan, tebyg i estrys, a oedd yn boblogaidd iawn am ei gig.
  The early settlers had never seen anything like the kind of wildlife that they saw there--flocks of penguins and elephant seals along the seashore, herds of guanacos similar to llamas wandering the plains, armadillos and skunks, Patagonian hares which they named ‘desert hares’, and the little rhea, similar to the ostrich, which was very popular for its meat.
