Aftermath of a winter storm

The western end of  the Mediterranean coastline of Southern Spain, closely linked to the Atlantic Ocean by the Straits of Gibraltar, may often be battered during the winter months by storms and wind, rain and high seas can cause a lot of damage.

When I first began visiting the  Guadiaro Nature Reserve in Sotogrande in 2004, there was a boardwalk in place that began at the entrance to the beach, ran right along the edge of the reedbed and ended at a rotunda set close by the mouth of the estuary. The structure made a good viewing platform from which to look over the reedbeds as well as offering protection to the reserve area, keeping people and dogs at bay.

Winter storms soon began to take their toll on the woodwork and repairs were made each spring until they more or less admitted defeat and/or ran out of money in 2007. I made this entry in my journal on January 30th 2007, following a particularly dramatically stormy weekend.

Keen to see the effects of the weekend’s storms and to take advantage of a sunny morning, I decided to head for the Reserve to see what was about.

The reedbeds around the lagoon have been battered and flattened by the storms; much will have been done by the wind, but I suspect that the sea may have reached over there too. At first it appeared that there were few signs of life; nothing moved on the water, although I could hear the sounds of small birds about in the reeds and shrubs around the hide. The belting calls of a Cetti’s Warbler were so close I thought that today I may have a good chance of seeing the elusive little bird, but no luck again. Then a Chiffchaff called and appeared for me to see, complete with a leg ring.

A beautiful brightly-coloured Blue Tit arrived to feed on the reed seed-heads, again complete with leg ring.  One of my biggest bug-bears about people using this little stretch of beach is the amount of rubbish they leave behind and there’s nothing like a good storm for exposing the extent of the problem. It seems so wrong to see beautiful birds rummaging around plastic bags and bottles in what should be a natural setting; but then on the other hand, the birds are probably around the rubbish as it attracts, or gives cover to insects. Birds are quick to learn to exploit our less savoury habits and are far more concerned with survival than aesthetics.

A beautiful Robin appeared from low down amongst the reeds to perch on an old cut stem and a handsome male Black Redstart flew in to take up a higher viewpoint; both had their feathers well fluffed out against the chilly breeze.

A pair of Moorhen emerged from the cover of the reeds at the water’s edge to investigate the area in front of the hide. They too are in their breeding- best now, with glossy, colourful plumage and bright shiny yellow-tipped red beaks.

Breaking the peace, a flock of about ten or so Snipe  flew in fast and explosively, scattering themselves and rapidly settling into various spots around the edges of the water, where perfectly camouflaged, they effectively disappeared from view in seconds. From over the top of the hide, almost simultaneously with the Snipe, a Marsh Harrier swooped over the water, landing in on a low shrub a short distance away in the midst of the long reeds; maybe chasing the snipe? Surprised,  I didn’t even think to grab my binoculars. I watched and waited for quite a while to see if it would move again, but it seemed content to stay put.

Outside the hide the sun was bright and it was warm but there was a definite nip in the air; the best winter weather, although it didn’t look set to last as there was plenty of cloud around too.

Walking towards the beach, I heard Fan-tailed Warblers, saw more Chiffchaffs and a Sardinian Warbler, I heard the Cetti’s again and watched a Moorhen that was swimming about close to the nearside edge of the lagoon, it was flicking its wings and flashing its white tail-end; perhaps the Marsh Harrier was still about.

Arriving at the boardwalk it began to become apparent that the storms had once again wreaked their havoc on this ill-fated construction. The ramp to the new rotunda had separated from it, leaving a wide gap to step across to get onto it. But that was minor damage compared to what had happened further along. Much of the new length of boarding that was only put in place last year has been shattered and incredulously, whole sections have been lifted and hurled piecemeal back to the edge of the reedbed.

It’s such a shame after all the time and effort that went into rebuilding it, but you do have to question why previous experience hasn’t led to a more substantial structure being built. I wonder how long it will be before it will be repaired this time, if at all? The major problem now is that it leaves the reserve open and vulnerable once more as there is no fencing to protect it either.

A lot of pebbles have been dredged up from the seabed and piled up in places to cover a lot of the previously sandy beach. Large numbers of cockle shells have also been thrown up and mainly scattered randomly along the sea edge, but in a few places there are piles of them. Some were evidently alive when wrenched from their rocky homes and now the poor dead animals await being eaten by gulls or flies. It’s quite a gory sight to see them like that, but its surprising how differently we view them when they’re cooked and on a plate!

Unusually, there were quite a number of Cymbium shells of varying sizes, with one of them also still containing the animal. I have only ever found two of these lovely shells before, one sun-bleached one on the sand on the water-works side of the beach and the other here a short while ago, but broken. Research I have done puts these as native to the seas around the coast of Portugal, but I suppose that’s not so far away and they could easily be carried through the Straits to arrive here. It is interesting that they were all thrown up in the same spot though, I wonder if they are, or maybe were, living in one of the reefs close to the shore?

There were dozens of oranges scattered along the length of the beach as there often are after stormy weather. I don’t know for sure, but I imagine they arrive here after being carried downriver out into the sea and are then washed back in again.

More Chiffchaffs flitted back and forth between the shrubs at the back of the beach, where there was also a Sardinian Warbler, a Robin and several Goldfinches. Cutting across towards the estuary there were Cormorants flying hurriedly to and from the sea and the usual host of Yellow-legged Gulls. There were more on the water together with a smaller number of Black-headed Gulls. A  Grey Plover, a Turnstone and a small flock of Sanderling were resting behind some debris.

The water level of the estuary has risen  considerably and the sand around it was still very soft and waterlogged so walking further around was not going to be easy, so I turned round and took a brisk walk back the way we had come.

A Grey Wagtail flew in over the reedbed to land by the water and near to the rotunda a pair of Stonechats came out to perch atop a low shrub, the male flying up and diving down; their characteristic display to a female.

Getting back to the spot where the shells were washed up I stopped again to see if I could find anything else, I sat down on the sand at the back of the beach and lost in thought I didn’t immediately notice that there were three Turnstones very close by pecking around in the sand and taking no notice of me either. All that spoilt the moment was the plastic supermarket carrier bag immediately behind them.

Back on the path going out there seemed to be Chiffchaffs everywhere; flying around the stands of tall reeds that grow on the land in front of the buildings on the opposite side to the lagoon, perched on the wire fence and in or on almost every available shrub. It would seem that they are on the move, maybe they stopped here en route from Africa to wait for the storms to pass.

My Bird List for the morning was quite amazing, amounting to 22 species:

Cormorant; Common Moorhen; Marsh Harrier; Purple Swamp Hen (Gallinule); Grey Plover; Sanderling; Turnstone; Common Snipe; Black-headed Gull; Yellow-legged Gull; White Wagtail; Grey Wagtail; Blue Tit; Goldfinch; Robin; Stonechat; Black Redstart; Common Blackbird; Cetti’s Warbler (heard); Fan-tailed Warbler; Sardinian Warbler; Common Chiffchaff (numerous);

Cormorants on display at the Estuary

Sunday 20th February 2011

A sunny day, clear blue sky, bit of a breeze but warm enough to head down to the Reserve and Estuary to see what was happening there.

At the Reserve there were butterflies, a Holly Blue, Speckled Wood and Large and Small Whites; there were also Violet Carpenter Bees zooming about. The water level of the lagoon was high, but there was very little to see – a Coot, a Moorhen and a couple of stacks of Terrapins hauled out on the reeds, which are beginning to green up.

The lagoon was quiet, just a Coot, a Moorhen & terrapins to be seen

Arriving at the beach I saw I had it to myself, so I stood for a while gazing out over the unbelievably blue-green toned sea, its surface ruffled slightly by the breeze and with a white – sailed yacht strategically placed on the horizon against the clear blue sky. Peace, quiet and beauty, just for me.

Now this is how the Mediterranean Sea is meant to look!

The beach was littered with bamboo stems from the reeds and of course a sprinkling of oranges brought down by the rivers, as always following stormy weather.

There were Yellow-legged Gulls flying around, some of them circling up so high in the sky that I first though they were something more interesting.

Reaching the Estuary I saw immediately that once again Cormorants were going to be today’s main event.They are looking at their very best now and perched up on the branches of the fallen tree parts, plumage gleaming in the sun, very photogenic.

The birds (and I), were disturbed for a while as some over-excited children with a large dog arrived and began splashing about in the water, but the birds soon returned once the children had left. Some of them flew back directly to perch while some landed on the water and sailed in, as the three in the picture below. I love this image and it brings so many possible captions to mind it makes me smile every time I see it. Little things please little minds…

Apart from the Comorants and the mass of gulls there were few other birds around the estuary area. In the tamarisk shrubbery I did see a Great Tit, a couple of House Sparrows and a Crested Lark that flew out to the debris at the side of the water and I heard a Cetti’s Wabler several times. Walking back I caught glimpses of Stonechats that perched briefly on reed stems or the tops of shrubbery, saw a couple of Blackbirds and heard Sardinian Warblers.

 

A Violet Carpenter Bee on the thatch of the hide roof

The last thing I stopped to watch before leaving was a Violet Carpenter bee that was flying around the roof of the hide. This is pretty much always a reliable place to see these lovely giant bees; on a sunny January day last year I arrived here in time to see twenty or so of them around an old decomposing tree stump, probably recently emerged from a nest there.
