5th March - Shapwick Heath, RSPB Ham Wall and Litton Reservoirs, Somerset

After the climb of Glastonbury Tor on Friday and the views across the Somerset Levels it was down on to the Levels the next day.  Parking in the RSPB Ham Wall car park we were greeted by a male Pied Wagtail, inspecting the puddles.  At this time of year thoughts go to White Wagtails, but not this bird.


From the car park we walked along the main path heading west towards Shapwick Heath following the South Drain.  A Great Egret surprised us as it flew low over our heads and then dropped into the reeds on the other side, there were also several distant birds on the far side of Noah's Lake.

The great expanse of water that is Noah's Lake didn't have the quantity of duck that were present back in January.  The same species were present but in much reduced numbers.  In January there was the continual whistles of Wigeon, but today there was hardly any calls at all other than the squeak of a Moorhen, or the call of a Little Grebe to its mate.

On a pool close to the path there were several Pochard drakes, scanning the water there was no sign of any females.



We walked all the way to the road that crosses the heath and then turned to the left and headed towards the Canada Farm area.  Walking down the track towards the hide there was a Great Spotted Woodpecker and lots of Redwings in the birch trees.  In the hide it was very quiet, hardly any duck on the water.  At the back of the lake a Marsh Harrier twisted and banked over the trees.


The area is also a large expanse of reeds which contrast with the darkness of the trees and steely blue grey of the water.


The clouds were beginning to break up and the sun was coming through and while there was little on the water to interest us, the clouds and sun above the water once again lended itself beautifully to the black and white photography.


Leaving the hide we walked back along the track to the road.  Siskins were feeding in the alder alongside the track and caught this Blue Tit using the many twigs and branches to get a drink from a very dirty muddy pool


Further along we disturbed many Fieldfare from the trees, while some were feeding in the adjacent field.


We walked back to the bridge that takes the road across the South Drain, with the sun now out the scene looked quite dramatic once again looking towards the Calcott Lows area of the Avalon Marshes


After a coffee in the visitor centre we made our way back towards Ham Wall, the clouds and sun above Noah's Lake produced a quite dramatic landscape, once again in black and white to increase the impact.



The reeds as well glowing in the sunshine against the dark background of the distant trees.


A Little Egret for a change on the open water in front of the elevated hide, with Wigeon and Gadwall in the foreground.


We carried the walk along the South Drain and made our way to the first viewing platform on the Ham Wall reserve.  Once again the number of duck on the open water was much reduced compared to our visit in January.  On the pool on the other side from the viewing platform there was a pair of Great Crested Grebes building a nest together.  I watched and waited in the hope that they would enter into a display, but they were more concerned with nest building.  Where the reeds had been cut there was a good number of Snipe.

From the viewing platform a female Marsh Harrier drifted across the reeds before dropping down out of view.


A male then appeared and slowly made its way from the back of the reeds and then above us quite high.



The female then reappeared over the reeds and used the wind to travel quite quickly across the top of the reeds.



A pair of Stonechat were in the bramble bushes just in front of the platform.


Having decided to leave I just caught sight of the grebes now displaying, unfortunately too far away and just as they were finishing.


We headed back to Litton, where there was still some time to walk around the Litton Reservoirs, these are two reservoirs owned and operated by Bristol Water that can be found close to The Litton where we were staying.

The individual lakes are called Lower Litton and Upper Litton. The former is 8 acres in size with a shallow area and plenty of weed, the latter 16 acres and is much deeper than its sister lake and very different in character. Long and narrow with steep sides, and is fed by the River Chew which flows in at the top end. They were built around 1850 by the Bristol Waterworks to bring water from the Mendip Hills to Bristol. 

We walked from the car park and then followed the footpath that goes around the Upper Litton north bank.  The water was quiet but as we walked close to the bank we disturbed Mallard and Coot and this seemed to spark a territory dispute in the Coot.  All of a sudden there was splashing and below us a pair of Coot were engaged in a very fierce fight.



The fighting is over territory and not necessarily the female, if another bird enters into another's territory the first threat is swimming towards each other with the wings arched above the back, making both birds look bigger than they actually are.  Sometimes this succeeds in diffusing the situation and both birds back off.  However if it doesn't the next action involves one bird flying at the other like a black rocket, their neck stretched out and their feet pattering on the water.

When that doesn't deter the intruder and fierce battle is the final recourse and this was what we were now witnmessing


Water going everywhere and wings beating as a black mass twisted and turned on the surface of the water.



Each combatant leans right back, resting on the water with its wings, and attacks with its green legs and feet. It may try to grasp its opponent’s breast with one foot, and strike with the other. It will also try to get on top of its enemy and push it under water.
 


Feet were flying and both individuals were aiming pecks at the head of its opponent.







Finally one gave way and swam off, with the winner and its mate chasing after it to ensure it got the message.  Some fights involve three birds, with the mate of one of them joining in. The fight can also be to the death and an unlucky coot is sometimes found dead, either savaged or drowned, at the lake’s edge.

Leaving the Upper Litton we walked down to the lower Litton reservoir, where it was much calmer, up to eight Little Grebe were seen at one time.


Walking around the bottom of the lower reservoir we disturbed several Teal from the run off stream.

We then decided to make our way back to the dam and back along the Upper Litton path.  This was extremely narrow and very muddy in places.  This made it very difficult walking and sometimes in places quite a challenge not to slip down the bank.  Finally we reached the main dam and was able to re-trace the path back around the top of the reservoir.  The Coot were all quiet as we passed.
