When I went to sleep last night the oppressive humidity of the afternoon had given way to a cooler breeze which brought rain. I woke to a clear morning. The sun had not yet cleared the horizon, but the orchestra of birds was in full swing. A coppersmith barbet supplied the metronimic rhythm as the competing trills of green bee-eaters and purple sunbirds rose over it. The parrakeets joined in, and I thought I could hear an Alexandrine call amongst the rose-ringed.
I made my tea and looked out. The break in the clouds was the promise of the approach of sharad ritu, that interval before autumn that the English named an Indian summer. The sky was a blue that was almost impossible to see in Mumbai since the 1990s. The anthropause has made a big difference to the quality of the air. The crows had just begun to get into the swing of things. I was always a night person, more familiar with the late rising constellations than sunrise. But I’ve begun to enjoy this interval between sunrise and the start of human activity.
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.
I’m afraid I didn’t quite keep track of when it started raining. Perhaps it was July 3 (if it wasn’t earlier). Since then it has stopped raining for an hour or two a few times. The lawns get flooded whenever the tide comes in, and the water drains out slowly through the ground when the tide recedes. We live on borrowed land, after all (a friend sent me a photo from the 1950s showing the open sea where we live now). The rain hasn’t stopped long enough for the gang of crows to crowd flooded parts of the lawn looking for little tidbits flushed out by the waters (this two years old photo was thrown up by the photos reminder). So they have been crowding the windowsill of our kitchen, trying to look in!
I neglected my fitness regime to lean out of a window at sunset and enjoy the golden light. At this time of the day the skies are dominated by two combative gangs: the parakeets and the crows. Fifteen parakeets sat on one tree, or is it sixteen? Sixteen crows were in another. When I saw them, I remembered reading something about how intelligence and complex social structures evolve together. I hadn’t read about birds and their cognitive abilities much, except for tidbits about how crows can recognize human faces, songbirds can learn from others, and that pigeons can follow roads. So I looked up what is known of the brains of birds and was surprised out of my neocortex. Apparently birds have incredibly complex brains, which are organized completely differently from ours. An article gave a nice analogy, mammalian brains are organized like a club sandwich, in layers, but birds’ brains are organized like a pepperoni pizza, with different bits sitting next to each other. Most surprising of all, apparently the language learning part of our brains is functionally similar to that of parrots and songbirds, who also learn from hearing each other.
But the biggest surprise of all was a paper published just a couple of months ago. It seems that someone has measured brain to body ratios in a large sample of birds, and from fossils of avian and non-avian dinosaurs. The complex brains of birds began evolving when their bodies they became smaller than those of their saurian ancestors, but their brains did not change in size. After that some have evolved larger brains by growing big in both body and brain sizes, but with more rapid growth in brains. Of these, it seems that parrots and crows have the largest brain to body ratios, and they are right in the same ballpark as us. We’ve all heard about the fabulous ability of parrots to memorize phrases and say them back to us. I didn’t know that they rank with the crows in their ability to recognize human faces, and tell them apart. It’s more than I can do with parakeets. There are even claims that they can recognize that their companions can reason just like them.
There is a crow which sits on my window as I sip my tea in the morning and read the newspaper. Sometimes I’ve caught it craning its neck as if it was trying to read the paper. Maybe it was!
With the physical distancing of people in full swing, it seems that we are all beginning to find new connections to the world around us. I get up in the morning and hear a wonderful natural concert put up by the birds around us. There are familiar calls, as well as new ones I’m learning to recognize. You make a lot of new friends when you give them some time. The sun comes over the nearby rooftops as I put away the drying and make a tea. The concert in raga Lalit gives way to the long Bhairavi of the morning as I sit down with my tea. This is the new soundtrack of my mornings.
Among the most distinctive voices in the earliest raga are Coppersmith Barbets (Psilopogon haemacephalus, recorded by Tushar Bhagwat). They hang around the garden all the year round. Their monotonous call is a constant background to every morning’s concert. Even in ordinary times I hear them more often than I see them.
A pair of Indian Grey Hornbills (Ocyceros birostris, recorded by Tushar Bhagwat) visit the garden every year to nest, and bring up a new brood. Their arrival is a sure sign of the end of winter. I took the photo here a couple of years ago, in October, some time before they left the garden.
The call of the Asian Koel (Eudynamys scolopaceus, recorded by Paul Bourdin) is another sure sign of spring. The call of the koel has been part of the cultural landscape across India for centuries. There is even a 15th century poem by Uddanda Shastri about a koel who carries a message from a lost man to his lover, modelled after Kalidasa’s Meghdoot.
In the past I paid more attention to the spectacular colours of the Indian Golden Oriole (Oriolus kundoo, recordings by Frank Lambert and Peter Boesman) than to its call. Now, as I try to tease apart the content of the mornings’ symphony, I am beginning to recognize it by its voice. How does the same bird have such a harsh call, and a beautiful singing voice?
The Green Bee-eater (Merops orientalis recorded by Conrad Pinto) is such a beautiful bird that I’ve spent a lot of time photographing them, and I know its call fairly well too. But disentangling its voice from the morning’s background score is still a little difficult for me.
The lively chirping of House Sparrows (Passer domesticus, recorded by Peter Boesman) starts later in the morning. I wonder whether they wake up late, or whether they are too busy foraging in the morning to vocalize much. Does anyone know? In any case, the sparrows’ chirps are a transitional point. After that the Lalit raga, the raga of dawn, dies down and there is a transition to the Bhairavi raga of the day.
This is the time of the Rose-ringed Parakeet (Psittacula krameri, recorded by Rajagopal Patil). These gaudily coloured and combative birds have free reign of the airspace around trees during the day, and fly about with their constant screeches. Portunately they are gregarious, and when they congregate on a far spot, other birds can still be heard in my neighbourhood.
I have a suspicion that there is a Purple Sunbird (Cinnyris asiaticus, recording by Peter Boesman) somewhere in the garden. In the middle of the morning I think I’ve heard the chirping of this bird. During normal days we wouldn’t be paying attention to birds at that time, so neither The Family nor I am sure whether we have seen one. After we can move freely, we will keep a watch for it.
The Red-vented Bulbul (Pycnonotus cafer, recording by Conrad Pinto) is a common bird, whose call I know from childhood. There are a few of them in the neighbourhood. I hear them intermittently during the day, and late in the afternoon, when I go for a walk, I pass a tree which seems to be a favourite hang out for a bunch of these loudmouths.
Perhaps the most annoying bird is the common myna (Acridotheres tristis, recorded by Peter Boesman). Their call is sweet enough, if heard from far. But one of them has decided that my shower is its day room. It sits on the window sill and lets off a full throated taan. This would also be wonderful, but due to some peculiarity, the space around the window acts as an amplifier which sends an incredibly loud version of the song through the aparment. I would give him a wonderful reference if he is seeking a position elsewhere; I really want to get rid of him.
There is little to be said for the Blue Rock Pigeon (Columba livia, recorded by Mike Nelson) except that it brings a certain gravitas to the daytime ragas. The cooing is often interrupted by the noisy beating of wings that you hear in the recording, as it takes flight from the slightest perceived danger.
No description of the sounds of an Indian city can be complete without including the House Crow (Corvus splendens, recorded by Peter Boesman), whose social behaviour, aggression, and intelligence are keys to their survival against much larger raptors. The typical raucous call that you hear in this recording is by far the most common vocalization of the crow. It has many others, including a throaty croak that sounds a little like it is trying to say nevermore while clearing its throat.
I suppose if I’m stuck at home for much longer I can produce a blog post with the birds that I hear less often. For now a dozen is enough.
