13/10/2018 Day 3/4 in Norfolk with Marcus Nash: Snettisham and Titchwell

Saturday 13 October 2018
Day 3/4 Marcus Nash Norfolk Trip.
Snettisham and RSPB Titchwell.

  • Highlight of the day was the high tide spectacular at Snettisham.  This event never ceases to amaze me with thousands upon thousands of birds on the move.  So many Knot, Oystercatchers, Dunlin, Curlew, Bar-tailed Godwits etc. My fourth such experience and just as enjoyable as the first.
From late summer to early winter tens of thousands of wading birds gather on the mudflats where they roost overnight. During an incoming tide, these birds are pushed closer to the beach and on a high spring tide vast flocks of knot, dunlin and oystercatchers take to the air en masse as the high tides cover the mudflats. The commotion of thousands of wingbeats, excited calls and swirling flocks creates an exhilarating nature spectacle.
During winter months up to 40,000 pink-footed geese make their way from Iceland and Greenland to gather on the The Wash. At first light they take flight in close V-shaped formations of trailing skeins across the pale sky of a Norfolk dawn. The high-pitched 'wink-wink' sound of geese calling to each other resonates across the seascape then slowly diffuses as they head inland to find food for the day.
  • On the lagoons there were at least 10 Greenshank and 4 Spotted Redshank

We then relocated to Titchwell for the afternoon session and the highlights there included:-
  • a very late juvenile Black Tern was seen out to sea.
  • my biggest disappointment was missing the incoming Merlin from the sea.  Try as I may I couldn't get on to this bird - my 3rd such failure this year!
  • a close but obstructed view of a lazy Jack Snipe form the Island Hide.
  • up to 3 drake Red-crested Pochards and 3 females.

13th Oct 2018 – Four Autumn Days, Day 3


Day 3 of a four-day Autumn Tour today. It was still very windy today, but otherwise it was mostly bright and fairly sunny, apart from a band of sharp showers which passed over late morning. It was very warm too, up to 25C in the afternoon – unseasonally warm for mid October and t-shirt weather out of the wind!
It was forecast to be a big spring high tide this morning, so we planned to head over to Snettisham to watch the waders. However, with such a strong southerly wind, it would undoubtedly hold the tide back and stop it from completely covering the mud. So we figured the waders would remain out on the Wash today and consequently it wasn’t worth a really early start to get there well ahead of the tide.
The tide was already in when we arrived just after 9am, and we could see all the waders gathered in the far corner, just as we thought they would be. As we walked down towards the far end of the seawall, something spooked them and all the waders took off. We stopped to watch them all swirling round, making different shapes in the sky, before they quickly settled again down on the last remaining bay of mud.

Waders 1
Waders – 80,000 Knot were swirling over the Wash today

Carrying on to the end of the path, we set up the scopes to look more closely at the vast flocks of birds gathered in the tiny corner of mud. They looked like oil slicks spread over the surface. Closest to us were the Oystercatchers, a much darker, black mass. The Bar-tailed Godwits were nearby, more loosely grouped. Through the scopes we could see their pale backs streaked with dark. The Curlews were widely scattered on the drier mud at the back. Along the edge of the water was one vast throng of Knot, packed in shoulder to shoulder, looking almost like a pebble beach!

Waders 2
Waders – mainly Oystercatchers, Bar-tailed Godwits, Curlew and lots of Knot!

More Oystercatchers were still flying in to join the crowd already gathered, shining white and black as they caught the low early morning light. Then suddenly everything was up again, thousands and thousands of waders, whirling round over the mud in vast flocks, twisting and turning. What a spectacle! We would see what we assumed was the reason – a couple of Marsh Harriers were quartering the spit of saltmarsh just beyond.

Waders 3

They settled again, but not for long. We could see more Knot come up in huge flocks further back, many of them coming over to the nearer group to settle. Then they were all up and swirling again.

Waders 4
Waders – flushed repeatedly by Marsh Harriers and a Peregrine

This time we spotted a different culprit – a young Peregrine. It made several passes over and round the huge flocks which twisted and turned, before drifting back over the saltmarsh. It had a quick tussle with one of the Marsh Harriers and then settled on a fence post out in the vegetation behind the mud.
The waders eventually settled again. The tide was already starting to go out again, and there was a bit more mud exposed already. This time the various groups were less concentrated in the corner and we could see different species. There were lots of Grey Plover and more flew in and joined them, flashing their black armpits as they flew. Out on the mud, close to the massed Knot, we could see a tight group of Sanderling, much paler than the other waders, shining white and silvery grey in the low sunshine.

Beyond the flocks of waders, lit up by the sun shining behind us, we could see dark clouds approaching from the south. We got round to the shelter of the South Screen just in time, as a sharp burst of heavy rain passed overhead. Even though most of the waders were still out on the Wash today, there were a few different species still to keep us amused while we sheltered from the rain here.
At least 13 Greenshanks were roosting in with a larger group of Redshanks on the back of the closest island, along with a few Turnstones. A large group of Oystercatchers were sleeping on the shingle bank further back, and down on the waters edge below then were several more Redshank and a single Knot.
The warden came in to shelter from the rain. He had been doing a count today and was able to tell us we had been watching 80,000 Knot out on the Wash. Wow! He also told us there were four Spotted Redshanks further back, roosting on one of the small islands out in the middle of the pit. When the rain finally eased off, we could see them in the distance, much paler than the Redshanks in front of us, but not as pale as the Greenshanks.
The Greenshanks woke up and started getting restless. One or two started feeding, running through the water, sweeping their bills quickly from side to side feeling for food. Several of the Redshanks woke up too and started bathing, throwing themselves headlong into the water and flapping. A Grey Plover appeared on the island just behind Greenshanks.

Then the Redshanks and Greenshanks started to take off in small groups and seemed to head back out towards the Wash. There were other birds here too. A Rock Pipit was chasing round with the Meadow Pipits and Reed Buntings, down on the gravel margins in front of the hide. There was a good selection of ducks and geese on view, including a Canada x Greylag hybrid with the Greylag Geese. A Little Grebe was busy diving close to the near bank.
There was a gap in the clouds and the rain stopped for a while, so we took advantage and walked round to Shore Hide, before another squally band of rain passed over, producing quite an impressive rainbow over the north end of the pit. There was still one Spotted Redshank on the small island, right out in front of the hide giving us a much better view from here. We could see its long, needle-fine bill. A single feral Barnacle Goose was in with the Greylags at the back.

When the rain stopped again, we headed out of the hide and started to make our way back to the car. There had been a report of some Snow Buntings in with the flock of Linnets along the shore. We walked back along the shingle and quickly found the Linnets but there was no sign of anything with them. The tide was now well out and several Ringed Plovers and little groups of Dunlin were now feeding on the closer mud.
When we got round to Titchwell, it was already time for an early lunch. The car parks were very busy, and we found the last space in the overflow car park, but thankfully the picnic area was empty. While we ate, a Swallow and three or four House Martins were hawking for insects over the trees, feeding up before continuing on their way south. A Goldcrest was singing in the edge of the pines behind us.
After lunch, we headed out along Fen Trail. It was very warm now out of the wind, but it was still breezy in the trees and we couldn’t find any sign of the Yellow-browed Warbler here. We couldn’t find the flock of Long-tailed Tits either – they had probably gone somewhere more sheltered, taking the Yellow-browed Warbler with them. A Chiffchaff was calling in the sallows.
There were lots of dragonflies enjoying the sunshine – lots of Common Darters and Migrants Hawkers buzzing round the sallows or basking on the boardwalk.

Round at Patsy’s Reedbed, the first thing we spotted were the Red-crested Pochard. There were six of them here today, including three smart drakes, numbers having gone up as the latter have emerged from eclipse plumage and from hiding. There were also lots of Gadwall and several Shoveler.

There were a few gulls coming and going from Patsy’s Reedbed, but not much else, so we set off back towards the main path and the rest of the reserve. A Cetti’s Warbler was singing from the bushes on the edge of the concrete tank road, but the rest of the bushes on Fen Trail and round on the Meadow Trail were quiet.
As we made our way up along the main path, we stopped to scan the reedbed pool. Another Red-crested Pochard, a female, was out with a few Gadwall on the water. There was a big crowd gathered on the path outside Island Hide, and we thought they might be watching the Jack Snipe, so we hurried up to join them. A snipe had been seen earlier disappearing into the vegetation but when we looked where they were pointing, all we could see was bits of a Common Snipe showing through the weeds as it fed.
From inside Island Hide, we had a better view of the Common Snipe when it finally poked its head round the edge of the vegetation. There were lots of Ruff out on the Freshmarsh still too, and a small number of Avocet which are lingering here, after most have gone further south for the winter. Otherwise, there were not many other waders here today.

There are lots of duck out on the Freshmarsh now, mostly Wigeon and Teal, together with a few Shoveler. The drakes are all still largely in dull eclipse plumage, so not looking at their best.
With the Jack Snipe not showing, we decided to head out to the beach, and come back to have another look later. As we walked out along the west bank path, a flock of Golden Plover flew in and circled over the Freshmarsh several times nervously, before eventually landing out in the middle.
A couple of Redshank were feeding on the Volunteer Marsh, in the channel just below the path. At the far end, there were more waders out on the muddy banks. An Oystercatcher was working its way round just below us and out along the edge of the water we could see Black-tailed Godwits, Curlews, a Grey Plover and more Redshank. A Little Egret flew in, flashing its yellow feet, and started looking for fish in the muddy water.

The now non-tidal ‘Tidal Pools’ were empty, so we continued on to the beach. The tide was out, but we found a sheltered spot in the lee of the dunes and scanned the sea. There were a few Great Crested Grebes out on the sea and a single Red-throated Diver. We could see a distant flock of Common Scoter, out towards the wind turbines, but they were hard to pick up on the water and easiest to see when they flew.
While we were scanning offshore, we noticed a tern fishing way off to the west. It’s agile flight, dipping down frequently to the water’s surface, and dark upperparts contrasting with white underneath immediately set it apart – a juvenile Black Tern. It spent ages flying up and down just offshore away to the west of us, gradually working its way back towards us, before it eventually flew past just offshore.
It is quite late for a Black Tern off here, though not unprecedented. Still, it was a nice bird to see. While we were watching the Black Tern, one of the group noticed a small raptor coming in low over the waves. When we all got onto it, we could see it was a Merlin. It eventually came in low over the beach at Thornham Point, though it was impossible to tell whether it was a new arrival from the continent or a local bird skimming over the waves to avoid the wind.
There were lots of waders on the mussel beds at the bottom of the beach, along with several small groups of Brent Geese. We made our way down for a closer look and had good views of Bar-tailed and Black-tailed Godwits side by side. It was very windy out on the sand though, so we put our heads down and walked back up the beach.
We wanted to have another look for the Jack Snipe, and when we got back almost to Island Hide we were told it had been seen briefly earlier but had gone back to sleep in the vegetation. Thankfully, someone walked back with us and showed us exactly where it was. From up on the main path, all we could see was the Jack Snipe‘s eye staring back at us, and only when the wind blew the vegetation back so we could see it!
There was a slightly better view from Island Hide. We could see more of the Jack Snipe, and had good comparison views of a Common Snipe next to it – we could see the different head pattern on the Common Snipe, with the single pale golden stripe over the eye and a pale central crown stripe.

A couple of helicopters taking off from one of the hotels in the village created a lot of disturbance, flushing most of the birds from the freshmarsh, and the Jack Snipe finally woke up and started bouncing up and down. Unfortunately, rather than starting to feed, it walked deeper into the weedy vegetation and disappeared.
There high-pitched yelping calls alerted us to a flock of Pink-footed Geese overhead. Several of them dropped down onto the Freshmarsh with the already gathered horde of Greylags. We also spotted a Yellow-legged Gull which dropping in briefly with the Lesser Black-backed Gulls for a bathe and a preen.
Unfortunately it was now time to head for home. As we walked back to the car, three Marsh Harriers were hanging in the air over the reedbed out on the Thornham grazing marsh, silhouetted against the late sun, gathering before going in to roost.
