Bangalore diaries - Kaikondrahalli lake visits

I visited 2023 November, so it has been close to a year.

26th October 2024

8-10am

To my delight, I discovered a skywalk across the Sarjapura main road, which meant I could not only get to, but could also return from Kaikondrahalli lake easily when the traffic would be bad.

 Photos and observations are at iNaturalist.  



The entry area is a complete turn-off.  There is muck in the water, it smells of sewage and quite sensibly the water birds do not linger here.  It is the western side and the north that have some bird activity.

The flocks of Little Grebe were not there this time.  And the Harrier was missing.  


But I saw Cinereous Tits, busy and vocal!  they were foraging in the scrub.  I spotted a moving flash of white on grey on the mud face to the west of the lake, and decided to check with my binoculars.  I did not know they were common in Bangalore, and I was happy to watch them for a while - there were a pair of them, and they had a regular gossip session going, chirping and wheezing to each other as they hopped and flitted around in the undergrowth.

The Kites and Cormorants were a plenty, as also the Swamphens. Dusky Crag Martins dived and glided over the water's surface.  The piercing call of the white-browed wagtail drew my attention to the stone bunds, where it was moving around.

Walking back home on the skywalk - it was 10 am but the weekend traffic was so light!


30th October '24

I went anti-clockwise around the lake today, and started with the wood spider, which caught me in its  fascinating web, metaphorically, and delayed my progress.  Try as I might, I could not get my camera to focus on it!

Ebird list for 30th.

A Spotted Dove called from the Tabebuia tree and sunbirds flitted around so fast that I could just catch glimpses of them.  Sunbirds are so busy, and so vocal, for some reason they fill you with a good feeling, a sense of joy.

These little drops of sunshine dotted the undergrowth, and I came to know they are called Hairy Beggarticks!!  What a strange name!


The stones were covered with fresh moss, renewed by the overnight rains.

The Tits were there, and I saw the shy white-cheeked barbet high up in the canopy, pulling fruits from the Kusum trees that lie the northern end of the lake.

On the stone bund in the lake were some very glum looking lapwings, and one energetic sandpiper!

The path is lined with these Millingtonias, dripping their jewels.  



2nd Nov '24 ebird checklist

My last visit this trip to Kaikondrahalli.  And I saw a familiar friend - a lone painted stork, surrounded by Spot-billed ducks and Coots.

The stillness and quiet made me stand and stare, and daydream for a bit.  I watched a kingfisher flash past.  I heard the Dove coo above me.  A jogger went by.  It was like an amplification of quietness.

This black kite also seemed to be enjoying a morning moment of quiet, sitting still and observing me observing it.

And then the magic was broken by a bunch of barking dogs who then went and parked themselves on the bund.  I hoped they were not hunting eggs or fledglings.

I did a U turn, retracing steps quite happy to go back to the quieter part of the lake rather than the road-facing part.  And I am glad I did.

There was a photographer sitting on the fence, and he greeted me with a smile and said in low tones - "chestnut headed starlings".

I looked up to see a bunch of them, in a mixed flock, with drongos as well.
This is what I captured.  A drongo and a chestnut tailed starling sitting on a Eucalyptus tree.


We both watched a pair of common kingfishers with their sharp calls, as they ducked from one dead branch to another. A Coucal sat in the open - forced to emerge from the shadows to dry its wet feathers in the sun.

It was a goodbye to the lake and its denizens, until next time.  

There are half-finished drain connections, iron bars sticking out dangerously, pigs snorting in the dirt and garbage, groups of stray dogs, and plastics in the water.  It is a wonder that despite this horror, the birds are there.  Maybe by the time I visit next, things may be better?  Maybe that's why the winter ducks are giving the lake a miss?

Patch birding in the neighbourhood

eBird Checklist - 20 Oct 2024 - 18 species

October 20th, Sunday 730 am

Patch birding on an empty plot that has water puddles and scrub overgrowth. Overnight rains. Now sunny.  This is an empty shrub-filled plot, off the main beach road at Thiruvanmyur.

3 Red-wattled Lapwing
1 Eurasian Hoopoe
1 Common Kingfisher (Small Blue Kingfisher) - what a nice surprise.  Sat on the wall next to the G Square developed plot.
1 White-throated Kingfisher
4 Blue-tailed Bee-eater
1 Coppersmith Barbet
2 Rose-ringed Parakeet
2 Black Drongo
1 Brown Shrike (Brown) - just shows the difference between incidental birding and binocular birding.  I saw this because I had a pair of binoculars with me.
7 House Crow
2 Large-billed Crow (Indian Jungle)
4 Common Tailorbird
1 Ashy Prinia
4 Barn Swallow
1 White-browed Bulbul
4 Common Myna
5 Purple-rumped Sunbird
1 White-browed Wagtail (Large Pied Wagtail) - Now I was delighted to see a pair of them later on the beach, foraging around the temporary lake/river that has been created from the stormwater drains that are emerging on the beach.  They hopped and flew all around the periphery, chittering to each other as they went.  

Number of Taxa: 18

The wildfowers in the thickets are here.  I also saw some dead marine creatures, which was not nice at all.

The patch where I saw all these birds.

I went on to the beach and the Valmiki Nagar thickets.

I love wandering in these thickets, you never know what you will find.  Today was a butterfly day.

The cricket match had driven the birds away, I guess.

My Valmiki Nagar thicket ebird list here.  Blue-tailed bee eaters were doing their aerial dives and a lone black Kite flew over the water's edge.



The sea looked lovely, and the clouds gave me a bit of shade every now and then.  

The waves fizzed back and forth, but the sand had these green algal residues, perhaps the phytoplanktons causing the bioluminescence these last few nights?

Mumbai Diaries - a chance encounter with composting worms via an art exhibition

4th October 2024

We happened to walk into this gallery as a rendezvous point to meet Sekar's cousin Viji more than anything else.  Sometimes I am moved by art and sometimes astounded, and of course quite often indifferent as well.  The evening brought all 3 emotions.

There were two exhibitions - one by a set of nine woman artists under the theme of Symbols of Care and Nurturing, and another called Factory 5.0 by architect Aditya Mandlik.  
I was moved by the insect-centred art of Nisha Dhinwa, Shalini Dutt's warm tapestry art, and the drama of Shayonti Salvi's ceramics.  They had a connection to the natural world that worked for me.  I did not personally connect with the other artists in this collection

And then we moved into another space, all dark and spotlit.  And this is what the write-up at the entrance said:

"FACTORY 5.0
This Pavilion envisions a future where design transcends human-centered thinking, fostering deeper collaboration with nature. Composed of 546 digitally manufactured wooden elements, 210 Styrofoam plates, and 10,400 non-human collaborators- enclosed in transparent acrylic containers - the installation challenges contemporary urban environments. 
Styrofoam represents matter once believed impossible to decompose - plastic. Through this collaborates with nature, the Pavilion demonstrates how decomposition itself can become an act of creating architecture. 
At the heart of the exhibition is the "Factory" concept, illustrating how creation can flourish through the cooperation of human innovation and natural systems. The installation embodies co-creation, where diverse approaches converge to reshape the future of our habitats. This living structure engages visitors in a dynamic experience where their movements influence light, subsequently affecting the worms' activity, thus fostering a dialogue between nature and design, continuously reshaping itself. 
As the Pavilion undergoes a curated aging process, the plates gradually develop openings, orchestrating a dynamic interplay of light and shadow. At the conclusion of the exhibition, these plates will be frozen as 'objects of memory; capturing the essence of time and space. Factory 5.0 redefines creation as a collaborative process, inviting reflection on the post-anthropocentric future, where human and non-human collaborators begin to coexist towards a symbiotic future."
Yes - 210 Styrofoam plates encased in acrylic.
And 10,400 "superworms" - Zophobas morio larvae of (what I later discovered) the Darkling Beetle!  
Busy chomping through the styrofoam in any which way they pleased.

Here are a couple of videos from the astounding installation, with the architect Aditya Mandlik explaining to us bemused lot including cousin Viji.




So of course, I was intrigued, and also a doubting "flowergirl" and therefore I had to put google search to full use.

I came across a  2015 Stanford Study quoted in an article The Science behind Composting Styrofoam.  






For three weeks, researchers at the University of Queensland fed superworms a polystyrene foam commonly used in building insulation.

The larvae that snacked on plastic were able to complete their life cycle, becoming pupae and then adult beetles. However, they gained less weight than superworms that were fed a bran diet, and had less healthy gut microbiomes.

Dr Chris Rinke of the University of Queensland, a co-author of the study, said within 24 hours, the superworms started “attacking the polystyrene and eating their way into it”.

“Within 48 hours … the faeces they produce turn from their usual brown – when they eat bran – to white.”

Rinke said the superworms first mechanically shredded the polystyrene foam, and microbes in their gut contained enzymes capable of breaking down polystyrene chains into styrene molecules.

The New York Times also reported on this study at the same time, and it made cynical me wonder if the Styrofoam lobby was at work at that point in time, trying to stave off the PS Foam ban that was upcoming in Australia. 

How Superworms Make Styrofoam Into a Healthy Meal

When the time came for the insects to metamorphose into beetles, those that ate bran completed the transition successfully nearly 93 percent of the time; those that had starved mustered only 10 percent. Strikingly, 66.7 percent of the polystyrene-eating larvae that were given the chance to pupate were successful. They managed to get enough energy from the notoriously indigestible substance to transform.

“Polystyrene is definitely a poor diet,” Dr. Rinke said. But “the worms can survive it — they don’t look sick or anything.”

The researchers sequenced all the DNA they could extract from the guts of the larvae. They were less interested in which specific microbes were present than in what enzymes were being made as the microbes worked to break down polystyrene. They pinpointed a handful of likely candidates — all types of enzymes known for their slicing-and-dicing abilities — that were possibly shearing polystyrene down into smaller pieces.

“The next step will be to express those enzymes in the lab and experimentally verify that they are doing what we think they are,” Dr. Rinke said.

So that's what Mr Mandlik is trying to do - get the superworms to eat the styrofoam and create spaces. 

The lab experiments are trying to isolate the enzymes and maybe solve our landfill problems in the future...but this architecture thing is a bit weird for me, ethically - keeping larvae from pupating and feeding them rubbish styrofoam does not sound like co-creation to me, more like another means of putting the non-human world to work in unhealthy conditions.  

So yes, it is a factory, with super worm slaves.  Let us not say "cooperation" and "co-creation", please.  The worms have to be kept together and their pupation hindered, for us to have our styrofoam chomped and processed.  

The Wiki page on Zophobas morio  is being spare with the truth when it says "Zophobas morio larvae fed a polystyrene diet were more active and managed to gain a slight amount of weight compared to the same type of larvae on a starvation diet" - 

Yeah right, eating plastic is better than starving.  The Chennai street cows would agree.

Mumbai Diaries - Karvi blooms and butterflies galore

October 3rd 2024

I was excited to learn that I was not too far from BNHS CEC.  

Various friends urged me to go - "it's a beautiful drive through the Aarey forests", said one. Another said, there are lovely bird trails  inside.  And then I saw that the Karvi flower was blooming there, and that sealed the deal, and I decided to go on the 3rd (and not the 2nd which was a public holiday and bound to see many a tourist.)


This was the scenic route I was looking forward to, as I hopped into the auto around 730 am.

This was the actual route taken by the speeding auto, who kept insisting that his map said this was faster.


It was around 9am by the time I got dropped off at the supposed gate, with not a soul in sight, after speeding on the expressway, standing still at innumerable traffic signals, winding our way through Film City, its various guards, potholes and vanity trucks.  The auto driver asked me if I was sure this was the place, and I confidently and cheerily told him so, and sent him off.

(It did cross my mind as to how would I make my way back from here...but at that point, just getting out of the rattling auto, away from the highway, and into bird call - it seemed like paradise.)


This was my first glimpse, as I crossed an empty school bus - whose kids must be wandering around the trails I surmised.  Sunbirds and Tailorbirds called incessantly.

A family of macaques observed me from the canopy above, sitting quite peaceably and grooming one another.  


And then, just like that both sides of the path were filled with these purple blooms!  Oh is this the Karvi flower, I thought and looked more closely, and yes it was.  Initially I must admit I was a bit underwhelmed - I mean one has to undergo some hardship and search high and low for rare one-in-8-year-blooms I thought - but here they were strewn on both sides of the path, in wild higgledy piggledy fashion!


I did warm up to them, eventually.  They reminded me of the Railway Creeper flowers, Morning Glories.  

I loved the buds more than the flowers, eventually.

Strobilanthes callosa - the Latin name - is an interesting shrub.  A favourite of all sorts of caterpillars and butterflies, I learnt, and is kind of brown and all dried up before the monsoons, turning all green and leafy after the rains, and then once in 8 years, it does this, bloom like there's no tomorrow.  

I learnt a new word - Plietesials - plants that flower occasionally and in synchrony.  Nature is quite amazing and marvellous.  Now if one didnt know this plant, it is quite imaginable that it will be discarded when looking all brown and shrivelled.  

Ruminating such thoughts, I walked on, and spied a building and heard some voices.  There were the kids from the school bus, with some harried looking teachers, and a very enthusiastic nature educator explaining the life cycle of butterflies.  A few children in the front were curious and eager, while those at he back had a "what am I here?" look to them.

I went to the "office", where the cheery guard asked me to sign in, pay the entrance fee of Rs 150 (only UPI please, no cash), and then I was free to wander on.

There is a Karvy trail and what's referred to as a Leopard Trail  - leopards have been seen in the park.  I did a bit of both.

Observations � iNaturalist - will give you the complete set of fungi, caterpillars, spiders and butterflies that I was able to capture on my phone camera.  Through my binoculars, I saw a huge number of chocolate pansies, Greater Orange Tips, Yellow Orange Tips, small white butterflies, Sailors, and many unidentified ones.

However, my bird list was small - the trees were quite silent for a lot of the time, was I too late for the morning chorus?  I was hoping for a sighting of the oriental dwarf kingfisher, but this is not the season I was told.

I could hear the Film City crews with their PA systems, shouting Action! Cut! etc etc.

It was a humid and hot and sweaty day.  I climbed up to the top of the Karvy Trail, and I could see a little stream below.  I think in a guided walk, they probably go down as well, but I did not venture.


As I headed back, I met one of the researchers coming up.  He was changing the card on the camera trap - they are tracking the leopards.  He said that he had just seen a rat snake.  I missed it.



Up in the skies above, there seemed to be two Oriental Honey Buzzards circling - they are not Black Kites for sure, but I could not find anyone to confirm the id.

Down below, the kids were complaining about mosquitoes and the heat - and the Guide was reassuring them that these mosquitoes did not carry dengue or malaria, and in fact were "tiger mosquitoes", with stripes.  I listened with amusement.  Another boy was hot and wanted water, a girl wanted to use the washroom - I was so glad I was not a teacher.  We really cannot thank our teachers enough.

It was time to return.  I did book an auto, who kept getting lost, but finally did show up, and was cheerful and apologetic for his lateness - he did not realise I was just grateful for a ride back!  I once again suggested Aarey road - but he told me - the "jungle road is karaab" and looking all jammed, and we came back also by the highways - more traffic and signals.  Oh well.

Sekar and Vish tried to reason that maybe the auto drivers knew something we/google did not, but I was not convinced. 

And so ended the BNHS CEC visit.

Mumbai Diaries - Kites and Sparrows, Cats and Dogs

eBird Checklist - 30 Sep 2024 - Raheja Vihar Circular Road - 16 species

I am in Mumbai, and quite close to Powai lake.  The area is wooded with exotics, but wooded nevertheless, and these are the birds seen in incidental birding - I did not have my binoculars with me, and I am sure I would have identified a few more warblers and possibly an oriole, if I did have one.

What I find interesting compared to Chennai bird-wise in this highly urbanised city is - 

# the strong presence of sparrows (I see them every time I come to Mumbai)
#  the very few crows (as compared to Thiruvanmyur) - I actually am not waking to crow caws, which is a pleasant change
# this neighbourhood also has less pigeons very interestingly


But the most heartwarming thing is the presence of small street dog kennels/shelters across the community...

and well-fed streeties, which seem to have been inoculated  - they have clipped ears and collars.  I am not a fan of random feeding without adoption, but this community seems to have adopted and care for the dogs.  Kudos!


Back to the birds and the trees.

Black Kites soar above all through the day.


The area is hilly, and I love the fact that there are some untended rather wild spaces, along with the buildings and the exotics.

One street has a lot of Australian Acacia in bloom, then there are Copper Pods, Gulmohars, Terminalia catappa (badams), and the ornamental palms.

But there is also the pink powderpuff tree, a few sarakonrai, mango and even a jackfruit tree!

A hillside that is wild - and I hope it stays that way.



"What would the world be, once bereft Of wet and of wildness?
Let them be left,
O let them be left, wildness and wet;
Long live the weeds and the wilderness yet."

Gerard Manley Hopkins, poet

7th October update


Came across Dusky Crag Martins nesting under the eaves of the Scottish Union school this evening!

Now all I need is a Peregrine.  Come on Mumbai!  Chennai is up to 14 Peregrines incoming as of date.  

9th October

A drizzly evening and I strolled in the building.

So many sparrows I see in this neighbourhood.  Usually I find them difficult to photograph as they zip from one bush to the other. In the day, they chirp away, and somehow to my human ear, it's such a heart lifting kind of sound, gives me a feeling of cheer and hope.  They come and visit our flat windows, perching on the railings momentarily before flying off.  I see them in many window railings across the community.

I have located three favourite evening roosting trees - one a Jackfruit tree, one an overgrown bougainvillea bush, and the third an ornamental ficus bush!  I love to watch them 

Today, however, in the rain, they sat and chirped on this railing, taking shelter from the drizzle, and I managed this vide from under my umbrella!

And there are many cats too, but they thankfully do not attack/stalk the sparrows - they seem well fed!

The cats are not like Chennai cats - where they scoot and make themselves scarce when they see you.  Here, they sit in the middle of pavements, bold as brass, fix you with a stare, with their tail swishing, sizing you up - will this human feed me or not?  

More updates, as and when.

Sholinganallur/Perumbakkam Marshlands

eBird Checklist - 22 Sep 2024 - Sholinganallur/Perumbakkam Marshlands - 29 species

I did not take a single picture - kind of rare for me.  So disheartened by all the disturbance.  

Chitra and I used to bring the NIFT students here, and the birds would be so close, it would be easy to get newbie birders interested.  Whether it was a swamp hen or a cormorant, or even those flamingoes.

Now the whole habitat is disturbed.  Birds are far away, the Fulvous Whistling Ducks kept circling and whistling.  The purple and grey herons moved in their slow and deliberate manner in what looked like polluted waters.

I was gladdened by the sight of a solitary avocet, and some blue-tailed bee eaters.

I did not see a roller, nor a raptor.  

But I did meet up with friends - Sagarika, Gangapriya, Tara and Ranjani.

Fluttered by

 

Yesterday morning 
a Great Eggfly came to rest
only for a while.

This time not to die
catch her breath, escape the sun
momentarily.

It was a different feeling from 2019 - final resting place.

Hypolimnas bolina, the great eggfly - female


Typically, the Great Eggfly underside has more white...so here is another morph then.


PS:  I have to admit - I thought it was a Common Indian Crow initially - lazy dying if ever there was one - and it was Sagarika, sharp as a nail, alert as ever, who said, nooooo!  not a Crow, too big, and see the frilly edge.

Greeted by a peacock!

eBird Checklist - 13 Sep 2024 - TTUF Nizhal - 11 species

Finally after many a month I walked over to Nizhal's TTUF today morning.

Crossing the canal, filled with water hyacinth and a whole flock of cattle get, with many in breeding plumage.  

As I stood and watched, a drongo swooped and picked an insect on the move.  On the right bank, a mongoose moved purposefully through the undergrowth.  A white-throated kingfisher, a flash of blue and a rattling call.


 
I was happy to see the trees all grown and green!  The Crepe Myrtles and Arjuna's were in fruit, the Palash was in abundant green as also the Garlic Pear tree - in March, it was in flower. the Mimusops was in fruit.  Has it been so long since I visited?

17th March 2024 - Crateva adinsonii - had dropped all its leaves, and a few flowers stood out, in full glory.

As Chitra and I walked along, a dog strolled past, followed by a peacock, if you please, - moving like a ballet dancer lightly and 'springily' into the far foliage.

Quite appropriately, the peacock flowers were in bloom

Looks like the park has an active night life - and I do not mean the snakes and other creature - which one would think would be a deterrent - but it appears not - Lust overcomes such fears I guess.

Hairy Caterpillar on the drumstick tree

9th September 540pm

I initially thought this was Metanastria hyrtaca caterpillars, but I think they are actually Eupterote mollifera caterpillars.

Seen on our drumstick tree.

They were all crowded on the bark of the tree, in the shade in the day - when I first saw them.  

8th September - Tree 1 5pm.  Not much movement seen.




9th September Tree 2 - they were alive and one the move.  Seemed smaller than the other tree caterpillars.  I could not locate the caterpillars on Tree 1.


I will keep a watch on the tree - Hopefully, the caterpillars do nt completely defoliate the tree.  According to the literature on the internet, these moths scrape and gnaw at the bark as well as the leaves.  I did not see any leaves eaten up.

More as and when I observe.



12th September
Looks like both sets of Caterpillars are on one tree now!

Subsequently, for many days I could not locate them.  Then I found some at the lower part of the tree, and some going to the base.

27th September

Hairy Caterpillars on one trunk and a bark gecko on the other.

The caterpillars looked worn and scruffy.

One liked like it was making its way down to the soil?

Pupal stage is in the soil, I read.

Some more close to the soil.



Bangalore diaries - Kaikondrahalli lake visits

I visited 2023 November, so it has been close to a year . 26th October 2024 8-10am To my delight, I discovered a skywalk across the Sarjapur...
