The weekend was completely free of rain. The clear skies and wonderful sunsets drew The Family out to the sea shore. She would come back gushing about the light, and the number of people who came to quietly watch the sunset. So yesterday, I took my camera and climbed up to the terrace on the roof of our building. The western edge of the terrace is lined with satellite dishes, and each of them served as a perch for a crow, sitting quietly and looking at the sun. They were a little distracted when I appeared, and were torn between watching the sunset and keeping a wary eye on me.
“When our minds are much affected, so are the movements of our bodies,” wrote Charles Darwin in his book The expression of the emotions in man and animals (1872). This observation started a whole scientific enterprise of understanding the value of emotions by comparing them in humans and other mammals. Much less is known about the emotions of birds. “Birds and mammals are thought to have evolved from different groups of Mesozoic reptiles … during the Carboniferous or Permian period. Yet, birds and mammals exhibit extensive convergence in terms of relative brain size, high levels of activity, sleep/wakefulness cycles, endothermy, and social behavior, among others,” says a recent review of the literature on negative emotions in birds. Little else is known about emotions in birds. But when I see crows watching the sunset, or soaring against the breeze as the sun goes down, the parallel with human reactions to the beauty of sunsets does not seem farfetched.
The clear air of the last few months, and the relative coolness of the last few days meant that the sunset showed a simple gradation of colour in the sky, so different from the strangely beautiful sunsets that we had seen until the previous weekend. As the sun set, The Family and I enjoyed looking at so many different kinds of clouds. The horsetail streaks of cirrus clouds 5 or 6 kilometers above looked white in reflected sunlight because the sun had not set on them yet. As the horizon rose above the sun, the most spectacular were the golden layers of altostratus clouds at a height of about 3 kilometers. Meanwhile, the fast drifting layers of cottony stratus, merely a kilometer or two above our heads, had already started looking black because they no longer caught the sun.
The moon was already up in the east. As colour faded from the sky, the last clouds to turn pink were the high streaks of cirrus: ice crystals condensing out of the air in the cold of the upper atmosphere. The city lights came on, to add a glow to the moonlight. Between the clouds and lights, there is no way we will catch a glimpse of comet Neowise.
