Outings in the times of COVID

July 10, 2020

How I go on nature/bird outings: I go with just two or three friends, all of whom are (so far) healthy. We wear our masks, and sit one person to an open window.

We choose locations where we are not likely to find any other people.

Here’s the rushing stream of the Suvarnamukhi, just upstream of T K Falls:

Here is the cascade at Thotti Kallu Falls:

Don’t do it if you are not comfortable with the idea! However, my visits to the Bannerghatta biosphere (Gulakmale, T K Falls area) have been extremely productive in terms of many kinds of life forms, including birds.

Here’s a Sirkeer Malkoha which the three of us (Biju, Prem and I) found foraging on the ground this morning, while exploring the general area. It then hopped on to a small tree, and stayed for a little while, delighting us before it flew off.

How snails reproduce

June 27, 2020

I had never given a thought to how snails reproduce, until I saw this at Jakkur Lake today (Sat, 270620)

IMG_8366

I then started reading a bit about snail reproduction, and found

this link

very informative.

Here it is:

survival through time are the characteristics of their reproduction process.

The first thing you should know about these terrestrial gastropod mollusks is that most are hermaphrodites. Hermaphrodite is called any organism that has male and female reproductive organs and therefore can produce both eggs and spermatozoa. It is like if the snails were male and female at the same time.

There are, however, exceptions. The snails of the family Pomatiidae differ from their relatives because they have separated genders, that is to say, each snail is either a male or is a female according to the reproductive organs that it possesses. It is relatively easy to recognize the gender since the species present sexual dimorphism: the shell of males is smaller than females.

Most terrestrial gastropods are hermaphrodites, but some snails do not have this attribute, specifically some freshwater snails like the Apple Snails and periwinkles. These two types of snails still have separate male and female individuals.

The reproductive system ends in an external opening located in the lower part of the body near the head, called the genital pore. Individuals reach sexual maturity at different ages, according to their species and their particular conditions. Once they are sexually mature, their sex organs acquire the necessary conditions to reproduce, but they can begin to mate later. Usually, land snails reach maturity between 6 weeks and five years of age. Some mature sooner or later if the conditions of their external environment are favorable or not to their development.

Courtship: what to do to get noticed?
When a snail is already mature can begin mating, that is clear, but how do they approximate each other?

Before the intercourse, both approach to start the courtship process consisting of a series of movements and attitudes that will finish or not in the mating. The entire process can last as little as 2 hours or as long as 12 hours. To find a partner, they primarily rely on their sense of smell and touch, as their visual capacity is poorly developed and devoid of hearing. They can recognize chemicals in the air that communicate the receptivity of some other snail nearby.

During the process, both land snails get closer, acknowledging each other and “testing the odds.” As they approach, they begin to interact in a more physical way and can touch each other with the help of their tentacles. Some move in circles and can bite the area of ​​the genital pore.

In the final stage of courtship and before mating, some species use a unique weapon: the “love darts.” No, it is not a metaphor, it is a structure of calcium or chitin that only sexually mature snails have, and usually that have mated more than once. Seen in detail, they indeed resemble pointed darts.

IMG_8365

When both are close enough and touch their genitals, they shoot their love darts. Darts are not fired away but are a contact shot. Usually, the two snails shoot the structures, and they pierce the skin of the other so that they are united. The dangerous thing about this is that sometimes darts can damage an internal organ or go through the body and exit on the other side.

The function of love darts is not transferring sperm but is a form of sexual selection, and observations concluded that garden snails (Helix aspersa) could increase their reproductive success. The mucus that covers a dart contains a type of hormones capable of increasing the chances of success to have offspring.

IMG_8364

Mating
After the snails shoot their “love darts,” copulation follows. The transfer of sperm through the penis may be reciprocal or unilateral; this means that either both transfer it, or just one of the snails. It depends on the species. Others prefer to self-fertilize, so they do not need another individual to lay eggs.

After fertilization, the eggs go through a process of growth inside the snail, until they are ready to be delivered. After that, both snails lay their eggs and bury them in separate places inside a small hole made in the topsoil in a cool place. The mating process of snails allows them to deliver eggs at a consistent rate.

It will typically take a snail egg two to four weeks to develop. (1) As soon as they hatch, they will immediately move into a survival mode, because their shells still are soft. Their first reaction as soon as they hatch is to find sources of calcium either eating the remainings of their egg or eating other eggs that have not hatched to get the extra nutrients.

In conclusion, the mating process of snails starts when reaching sexual maturity, followed by finding the right partner, copulating, locating and creating a place to deliver the eggs, hatching of the eggs and ending with the develop of small snails.

Fascinating, indeed!

The Bagworm Moth

The Bagworm Moth is great housekeeper.
It combines the roles of larva and sweeper.
It makes its surroundings free
Of all kinds of debris
It is definitely (than a housemaid) much cheaper!

Prey species at Bhootanahalli, 140620

June 15, 2020

A few of us

IMG_7621

had gone to Bhootanahalli Pond (in the Bannerghatta biosphere, on the Bannerghatta-Kaggalipura road)and after watching the Baya Weaver nest construction, made the gentle ascent up the hill to the Bhavani temple, on Sunday, 14 Jun ’20.

On the path, looking out over a distant slope to the east, we were amazed to find first a Gaur,

IMG_7634

then the even more surprising sight of a Nilgai, a Chital and a Blackbuck all sitting/grazing together

IMG_7637

and then a large herd of Chital, stags, does and fawns, crossing the hillside, on a clearing.

IMG_7646

It took us a while to realize that there were also some man-made structures (like a water trough) there, and we deduced that there is some kind of reserve area there. Could we have some more information about this please, and know what other mammals have been released there? Have only prey species been introduced?

I must say, that most of us thoroughly enjoyed the sight of these unexpected mammals, and one little boy was asking if we might be able to see tigers and leopards as well!

The photos of the animals are on my FB album (they were quite far away, so excuse the grainy photos)

Looking forward to learning more about the animals introduced here!

Begur Lake, a triumph of rejuvenation! 060620

June 8, 2020

The last couple of occasions I had visited Begur Lake, it was under renovation, and we were a little concerned about how the job would be carried out.

Well, on Saturday the 6th, a few of us

IMG_7125

decided to visit the lake, as Dhanapal has been getting such excellent images from there; and we were very happy that we did; the birds (and other living beings) are back at, and in, the lake.

The onset of the monsoon meant that we walked on to the lake bund. Following Dhanapal’s directions, we walked along the eastern bund instead of the western one near which the Panchalingeswara temple stands. We found several stands of reeds and almost immediately, our attention was riveted by the variety of birds that we found. Coots, Grebes, Egrets (all sizes), Herons (both the common colours of grey and purple) all went about their business of securing breakfast in their different ways, ducking in the water, or wading along the shoreline.

In a while, we could discern even more activity in the reeds. Streaked Weavers were building their nests, carrying long reed-leaves to one stand and expertly weaving them in;

IMG_7042

In this connection, I would like to add two excellent videos Ashwin has made, of Streaked Weavers feeding their young:

and

stood stock-still while their sharp eyes scanned the water; and a few Yellow bitterns, which are rather difficult to sight as a rule, were quite clearly visible as, clutching the reeds with both feet, they darted their beaks into the muddy ground for insects, snails or a small fish.

IMG_7065

The typical spider-like movement of these birds, along the reeds instead of over the ground, made them easy to identify, and tell apart from the Pond Herons.

IMG_7066

For many of us, this was a “lifer” (a bird being seen for the first time) and the binoculars and the cameras were very busy indeed!

One surprising fact was that there were far more Brahminy Kites than Black Kites, in a city where the reverse is often true. We enjoyed their soaring, and their swoops into the water to catch fish, the attempts being successful occasionally.

Cormorants, Little, Indian and Great, were in plenty, and flew in and out of the lake, stippling the water as they landed or took off. Overhead, too, they formed skeins as they disappeared into the brightening sky, perhaps bound for other water bodies. Several Darters added their zigzag snake-necks to our bird count.

Several Spot-billed Pelicans were found in the far reaches, while a few swam lazily around nearer to where we stood. We found only a few Spot-billed Ducks, and some Lesser Whistling Ducks, far away. Meanwhile, Ashy and Plain Prinias, and one single Clamorous Reed Warbler, delighted us at the front of our birding stage. Both the Bronze-winged

IMG_7178

and the Pheasant-tailed Jacanas wandered around, the males of the latter in their spectacular “comma-tail” breeeding plumage. For some reason, there were only two Painted Storks, one of which struggled (successfully!) with a very large fish, as we looked on.

IMG_7175

Purple Swamphens

IMG_7070

and Common Moorhens added both colour and black-and-red, and we saw the Pied, White-breasted and the Small Blue Kingfisher. Red-rumped Swallows collected mud for their nests, from the shore.

Indeed, I would say that Begur lake is an ideal spot for bird watching and bird photography. One does not need to walk far; the light of the morning sun falls on the birds; one can watch the behaviour of the birds at leisure, rather than just sighting them and moving on. The first frenzy of the cameras gives way to the calm use of the binoculars!

Nor were birds the only thing that caught our attention, Starting with a gleaming Jewel Bug at the entrance, many handsome six footers welcomed us to the lake. Pentatomid bugs, Net-winged Beetles,

different kinds of bees and wasps nectaring and gathering pollen

and several spiders which were ready to catch any unwary ones,

and flitted around as the sunlight warmed up; we saw Emigrants, Common and Crimson Roses, some Blues, Tawny Costers…and so the list went.

The lake itself was redolent with the peace of the morning. Scudding grey and white moisture-bearing clouds, across patches of freshly-washed blue skies;

IMG_7142

the reflection of those clouds, along with the old Panchalingeswara temple and the multicoloured buildings of Begur, in the waters of the lake; the fresh monsoon breeze and the gentle monsoon sunshine..it was utterly delightful to be out in the open air, enjoying all of this.

Alas, some trash has also made an appearance at the lake, as has some stagnant areas with stinking algae,

IMG_7160

but with the easing of the lockdown, I hope that the lake will be better maintained.

We shared our snacks (having removed our masks for a bit, in case you were wondering) and munched contentedly with the ease of undemanding camaraderie, and went homes with our spirits lifted and our memories, and memory cards, filled up!

Varsha…I wrote this three years ago…

May 15, 2020

IMG_0495

I thirst…
Not for love, money or
Even happiness.
I thirst for water
To quench the parched earth

IMG_4712

To bring green to the brown
To bring fresh hope to those
Who raise crops and food for us.

IMG_6590

I need water
To fill the pots
Of each slum-dweller
Who puts her (it’s never a he)
Vessel in a long line
And waits to drink, wash and live.

IMG_0429

I have had enough of grishma ritu.

IMG_0317

I want varsha…not just the odd shower
Or thunderstorm, but a steady,
Cloudy, drumming season
That will replenish the depleted
Plateau,that we live on
And call home.

Black-winged Kite!
Beautiful sight!
Once-in-a-while you greet me.
Small and grey,
Bird of prey
You look happy to meet me!

Ruby-eyed bird,
Who’s sharp of sight,
See-ing you.. Is sheer delight!
Small and grey,Bird of prey,
May you always greet me!

A tiny Golden Jackpot!

April 29, 2020

Sometimes a small success at home is as satisfying as getting a rare bird far away.

IMG_6988

On our terrace, the Red-whiskered Bulbuls (or as I call them, the Bulbullies) always chase away other birds which come to drink water or bathe , and I have been lying patiently in wait (when I get a little breather from the Endless Dishes in the Sink) in the hopes of getting Purple-rumped Sunbirds, Tailorbirds, a solitary Jungle Myna , and several of these delightful Oriental White-eyes.

Today I managed to click at exactly the right time! Certainly, before the lockdown, I didn’t know that I could find these birds in the middle of Jayanagar 4th T Block.

Morning walk during the lockdown,140420

April 14, 2020

My walk around the driveway of the apartment building this morning. Fragrances spilling from the jasmine on someone’s balcony, and from the Frangipani blooms; much milder, from the Parijata tree. An orchid spray holding its own for the past few days, in spite of the heat.

IMG_6698

A Tailorbird calling loudly, out of all proportion to its size. Mynas feeding on the palm berries.

Barbets flying from tree to tree. Several people taking their waste to the compost bin. A milk vendor delivering his daily quota. Dust on the parked cars, with no naughty little fingers drawing pictures or names on them. A view of the vegetable shop opposite the front gate, whose narrow entrance makes a joke of distancing. The first butterflies of the morning, flitting, large and small.

IMG_6546

The sun gathering power by the minute. The usual smile and “Good morning” to,and from, one lady who walks regularly, and the absence of response from other walkers, though I see them daily, too. The building security men with their masks on; they are an essential service. No newspaper delivery; I will return to read the Deccan Herald and Economic Times online, and print out the crosswords that make my early morning enjoyable.

The KK restaurant, Blr, 100420

April 11, 2020

=K1 and K2 opened a restaurant yesterday, and it was called the KK Restaurant.

A beautiful menu was prepared:

IMG_6690

Two customers seated themselves, playing some soft romantic music and dimming the lights:

IMG_6695

The Sous Chef also doubled as the maitre d’hote, and waited at the table:

IMG_6692

The Head Chef also gave the dishes his attention.

IMG_6696

The entree and the main course seemed to be Monaco biscuits with toppings of ketchup, cream cheese, olives and jalapenos, and chips with tomato sauce.

IMG_6697

Dessert consisted of chocolate biscuits, sadly depleted in the kitchen because the Head Chef sampled them too freely. (The same problem occurred with the Monaco biscuits, the chips and the cream cheese.)

The Sous Chef made a bowl of Maggi all by herself and divided it between the two customers. Alas, the Kitchen Manager-cum-Dishwasher (fired by the Head Chef for “disturbing the kitchen” and rehired by the Sous Chef ) was busy taking photos elsewhere and forgot to click the Maggi fine cuisine.

There were also delightful drinks of Blue Curacao, Orangeade, and Mint-flavoured water. Here’s the Head Chef, in his other role as the drinks waiter:

IMG_6691

The Dishwasher was thankful when service ended at the restaurant, because it already meant quite a lot of dishes and bowls to be washed and dried!

The restrauteurs took a bow from the deeply appreciative customers, as also an extra, elderly customer who came a little later. The customers paid the bill with hugs!
