In the tropics sunsets and sunrises are really short. In Far North Queensland it will go from daylight to black dark in under fifteen minutes (which can be quite startling if you are working under the rainforest canopy, concentrating on what you are doing, and suddenly realise it's dark.) Same but even faster for New Guinea and Borneo. And in all those places I love how the sounds change. Suddenly you hear the completely different calls of the night birds, the bats come out, the day-shift insects and birds and amphibians disappear and are replaced by the nocturnals, even the frog-songs change. Lovely.
Whereas nearer the Poles, morning and evening twilights seem to go on forever, and have their own beauties. I used to love the slow changes in the sky and the light, and watching the swallows and bats change shifts.
Now I wonder what changes the Illness and its mutations have made to the crepuscular ecology of Year 90 Copenhagen?
