In a few hours came “the season's difference.” The scene-shifter worked with almost magical haste, with silence, and with supreme effect. The gloomy days and nights of misty hill-tops and damp hollows, where the grass was sodden and the air dull and irresponsive to sound, gave way to bright sunshine, cloudless skies, calm seas, echoing hills, and the tinge of that which for lack of the ideal word we call “spring.” Spring does not visit the tropical coast, where vegetation does not tolerate any period of rest. When plants are not actually romping with excess of vital force, as during the height of the wet season, they grow with the haste of summer. And yet immediately on the dispersal of the mists of July the least observance could not fail to recognise that a certain and elaborate change had taken place. The mango-trees had been flowering for several weeks in a trivial, half-hearted way, but when the sun sent its thrills down into the moist soil the lemons and pomeloes began to sweeten the air; the sunflower-tree displayed its golden crowns among huge soft leaves, and the last blooms of belated wattles fell, showing that it is possible for tributes representative of May and September to be paid on one and the same date. The scene-shifter came softly “as the small rain upon the tender herb,” but with an orchestra of his own. Years of observation have shown that the weather does control the habits of some birds--birds of distinct and regular methods of life. Two such are common--the nutmeg pigeon and the metallic starling. Both species leave this part of the North during the third week of March, flying in flocks to regions nearer the equator. For several weeks the starlings train themselves for the long Northern flight and its perils, dashing with impetuous speed through the forest and wheeling up into the sky until they disappear, to become visible again as black dots hurtling through space when the sunlight plays on their glossy feathers as the course of the flock is changed. With the rush of a wind of small measure but immense velocity, the flock descends earthwards, among and over the trees, perfecting itself by trials of endurance and intricate alertness. The birds return during the first week in August, in small and silent companies, to reoccupy favourite resorts in common. The nutmeg pigeons are also of exact habit, the time for their return generally coinciding with that of the starlings. This year (1916) both birds were noticed just after the scene-shifter had swept the hills of mists, and now other birds seem to have awakened to the conditions which the starlings and the nutmegs brought with them from hotter lands. The swamp pheasants are whooping and gurgling, and that semi-migratory fellow, the spangled drongo--a flattering name, for he jangles but does not spangle--sits on the slim branch of the Moreton Bay ash which held last year's nest and chatters discordances in the very ears of his responsive mate.
