The Pheasant Tailed Jacanas of Pallikaranai

I remember when I first saw the Jacana walk on water (well almost), it just blew my mind, and I spent hours at Dungarpur just observing their spidery legs and jerky movements.  

The pheasant-tailed jacana (Hydrophasianus chirurgus) is quite common in the wetlands of Chennai, and always make for interesting sightings as they dart on top of the floating vegetation.

Mr Ramanan is a regular Sunday visitor to the marshes of Pallikaranai and Sholinganallur and has documented their courtship and breeding over several years. The females are larger and more colourful than the male and are polyandrous.  it is the males that incubate the eggs!

Mr Ramanan notes, "In 2016 in the month of June I had come across two active nests of Pheasant Tailed Jacanas closer to the road side itself. The female is polyandrous and the male takes care of entire breeding of the chicks."

Mr Ramanan noted that the smaller male chased the female with which he had previously mated, 
went underneath the bird, pushed it from the squatting position.  it looked as if the male was suspicious of the female, and did not want another clutch of eggs of another male in its territory?

In another instant, Mr Ramanan observed the male take the chicks under its wing, when a predator was sighted.  The alarm call had been raised by the female.
This is the male's protection posture, with all the chicks underneath, looking like a single adult with eight legs!

Mr Ramanan captured this picture of the female's frightened posture, with body erect but tail down.  (And do see those claws!)
"Once the threat disappeared they started feeding as usual."

"The breeding plumages of the sickle shaped tail with predominant amount of chocolate-brown colour and in flight a large amount white, was observed from the month of May to June this year. On one occasion when the early morning sun rays peeped through the clouds, it painted the female Pheasant-Tailed Jacana with the golden touch of rays which really accentuated its silky golden coloured nape."
Mr Ramanan continued his watch of the PTJs through the summer of 2016 and 2017.  "The sign of chasing all other birds like white breasted water-hen and purple moorhen, from their territory in the month of July, indicated that it has already laid the eggs.  As expected the first chick emerged on the 4th of August, and were seen with the male Pheasant-Tailed Jacana which had shed the tail by that time. I was expecting for some more chicks on subsequent days but it was not to be and the male has only one chick as on 11th of August. On 9th of August again came across the protection display. This time just like last year the female raised the alarm call when a common kite hovered over it and the male with the feeble call attracted the chick and took it under its wings.   The female immediately hovered over and chased the Common Kite. It is clear from the above that female also played an active role while breeding in case of threat, apart from the role of guarding their territory."

Incubating male seen at Sholinganallur.
Notice the large brown eggs! PTJ females usually lay a clutch of four.
When a Shikra was sighted, the male PTJ aggressively left its clutch unguarded and chased the predator.
Returning after a successful chase!
With his keen eye, patience and regular documentation, Mr Ramanan has been able to put together an entire series on the breeding of the PTJs, which makes for a fascinating account.

The marshes and wetlands of Chennai - important and precious for so many creatures big and small.

The comb duck at Sholinganallur

Comb Duck (Sarkidiornis melanotos).  Males have the "comb".
One of the largest of the duck species and seen if freshwater wetlands.
They are found in southern Africa and south Asia.  But not so often in Madras.
While I first saw them in significant numbers in Bharatpur and at Chilika, the 2017 bird race was the first time I saw them in my city.

All these beautiful pictures from Mr Ramanan, who visits the marshes almost every weekend!

COMB DUCK AT SHOLINGANALLUR

I love this duck, and I am so excited overtime I see it.  I didn't see it this time, but Mr Ramanan did, at Sholinganallur.

It's a large duck and shows up in our waters every other year. migrating down for the winter, and they look quite distinctive with their speckled heads and the 'comb' on the head of the male.

I need to go and pay a visit to Sholinganallur, soon.

INDIAN CORMORANT AT SHOLINGANALLUR

I have always struggled to differentiate the Indian Cormorant or Shag from the little cormorant. 
These wonderful pictures from Mr Ramanan helped me resolve the difficulties. 
Phalacrocorax fuscicollis
Notice the blue eyes and the smaller head. And the picture below shows the white threat that's restricted to just below the gape. 
Notice also the long narrow bill, which is longer than that of the little cormorant. 

The large cormorant is a visibly bigger bird and with plumage that is more black than the mottled brown black of this one.

Sholinganallur through the lens of Mr Ramanan

Sholinganallur in southern Madras is home to wetlands that are an extension of Pallikaranai.  Now known more for being part of the IT corridor, the area is in urgent need of preserving of the remaining grasslands, scrub, water bodies and wetlands.

These are the soak pits and groundwater charging areas for the city and support an important ecosystem.  Here are a few glimpses of that.

A beautiful capture of the conical silver bill, black tail and white breast of the White Throated Munia (Euodice malabarica), by Mr Ramanan.  These birds move around in large flocks and feed on grass seeds found in scrub and grasslands.  They are found usually in the winter months in south India.
A Black Shouldered Kite (Elanus axillaris) stares menacingly, just before taking off on its hunt for mice.  Its feet are usually clutch the perch from opposite sides.  These smaller kites live on a diet of mice, and it is amazing to see them hover in the sky as they hunt for lunch, dropping silently and speedily onto their prey.  Photo by Mr Ramanan 

The streaked fantail warbler (Cisticola juncidis) displays its fantail.  I prefer to call them Zitting Cisticola which is apt, as their call is a "zit, zit", as they zip past from reed to reed.  They are easily hard, but difficult to spot through the binoculars as they are always on the move.  Photo by Mr Ramanan
In the lake, Mr Ramanan's lens captured a winter visitor, the black tailed godwit, (Limosa limosa) a large wader, with the characteristic pink bill with the black tip.  The bar-tailed goodwill is more streaked 

Meanwhile on the shores, Mr Ramanan finds the brilliant colours of a yellow wagtail (Motacilla flava) in breeding plumage.  The wagtails, well, wag their tails quite incessantly and can be found on the dry periphery of lakes and other water bodies looking for insects.  This one seems to be a male with its olive upper parts.

Another species found in the dry scrub is the ashy-crowned sparrow-lark (Eremopterix griseus).  They look like sparrows.  This is a male with the well marked black collar, while the female is sandy brown.  They have an interesting courtship display with the male kind of shooting up vertically into the air, and then descending also with a whistle.  These are ground birds, foraging for seed and insect and also spending the night on the ground.  We need to leave enough undisturbed ground for these birds to survive and propagate.
