A Nesting Colony of Sea Birds on the Admiralty Rocks at Lord Howe Island. SEA Birds wander far and \\'ide over the oceans during the greater part of the year, but, at the call of the mating season, they foregather at chosen places to nest and rear their young. The colonies thus formed often include countless thous- ands of individuals, and may be com- prised of either a single species or of several different kinds. There is reason to believe that many birds repair to the same places year after year, regardless of the great distances they may have travelled betMeen whiles, and it is probable that young birds return to the islands upon which they were reared ^^'hen the time comes for them to undertake the res])onsitjilities of parenthood. The Admiralty Rocks at Lord Howe Island are a grou]) of islets of fantastic form, Avith a scanty growth of grass and occasional low bushes upon their rocky faces. They are difficult of access except in very calm weather, and are favoured accordingly by many sea- birds as nesting sites. Early in Decem- ber each year thousands upon thous- ands of Wideawake Terns (Onychoprion fuliginosa) wend their way in from the sea, and, meeting with their fellows, chatter loudly as they select favoured positions. Not that any one site would appear to be better than the. The Admiralty Isle
