The unusual ecological tale of Sippighat, Andamans

Our wonderful week at the Andaman islands included stopping by at Sippighat.  (The place names on the islands are a delightful mixture, and warrant an independent post - ranging from Junglighat, Dollygunj, Guptapara and Sippighat to Aberdeen and Rifleman Island!)

The newly formed Sippighat "wetlands".  All those black dots are waterbirds - whistling ducks, cotton teals and coots.

The tsunami of Dec 26th of 2004 changed many things all around us, and Andamans was affected in several ways, with an enormous human toll and ecological changes.  Some islands sunk by as much as a metre because of the earthquake, and at Sippighat, which is about 10kms from Port Blair the seawaters rolled in on a 10m high tsunami wave, and the land was inundated, and has remained waterlogged ever since.  The army has built a bridge to get across the newly formed water bodies.

Why could they not use these boats, I wondered.  or did the
tsunami wave wreck them?

We drove by the morning we arrived, on our way to ANET at Wandoor, and we saw the skeletons of drowned boats, submerged homes and abandoned building projects.

As we gawked in astonishment at this, a bunch of whistling teals took off from the water, with their characteristic whistling call, did a sortie and landed back in.  These freshwater ducks had obviously adapted to the now brackish waters of Sippighat, just like the Cotton Teal groups?

Up above, a White-bellied sea eagle glided lazily as a common myna flapped its wings busily, trying to keep up with it.  

We clearly saw the characteristic wedge-shaped tail, and raised wings while gliding

The Sea Eagle was a delight - it swooped down into the waters and picked up a fish in its talons, with one expert dive, and the bunch of us "aahed" involuntarily!

The waters were abuzz with bird life - swamp hens, coots and egrets of all sizes.  The swallows swooped around in the air above, but there was no sign of the Andaman Teal which supposedly is found here.

Cotton Teals swam by in groups - and in our excitement, the females were first mistaken for Andaman Teals.  A closer look and much discussion ensued, since none of us had seen an Andaman Teal earlier, it was worse than the one-eyed leading the blind!

The Forest Dept board finally did help, as quite clearly, the ducks we were seeing had an eye stripe and not the white ring around the eye.

It was a cloudy morning, and every now and then there would be a welcome thundershower for a few minutes, but yet we sweated inside our raincoats, the showers increasing the already high humidity levels.

The relatively new army bridge across the waters.  The waters have become a means of moving goods across the island.

We watched some feral ducks, kingfishers and a lone Great Knot busy in the mud.  Suddenly there was a commotion among the Cotton Teals, and three males were mobbing one hapless female, who was trying to get away, quite unsuccessfully.  I was sorely tempted to throw a stone at those male ducks and scatter them....should I have?

We were commandeered into the bus by Vijay, as Manish and team waited at ANET, and the cloudy sky looked ominous.

On another evening visit, on the way back from Chidiyatapu, we stopped again and this time Zoya from ANET took us in to another part of Sippighat and there we did see the Andaman teals (Anas albogularis) with their characteristic eye patch.  These are endemic to these islands, and are now considered as a separate species from Sunda Teals.  There are supposedly about a thousand of these teals. and we were privileged to see a large flock of them.

Once again though, for me, it was the White Bellied Sea Eagle that was most memorable.  We saw a pair of them, roosting in the trees beyond the waters, and what appeared to be a nest was spotted through our binoculars.

They took turns gliding over the waters, before perching majestically on the tree, settling down for the evening.
