In the search for new birds to add to the year list, the semipalmated sandpiper at Pennington Marsh was right at the top of the list. On Thursday evening, Kev @kev07713 got in touch to say that he’d realised the bird wasn’t on his wife’s life list, so they were planning to visit on Friday. Unfortunately, I already had a few things organised and wouldn’t be able to join them.
They had a great day, managing not only to see the sandpiper but also to visit and tick a Lapland bunting and saw both white-tailed eagles and ospreys - the location for viewing the eagles and ospreys had been suggested by our friend David South @davidso55441100. On Friday evening, Kev got back in touch to ask whether I was planning to head down to Hampshire on Saturday, as David was keen to go and see the eagles and ospreys himself, as well as the sandpiper and anything else that might be on offer.
I said that I was going, and it was agreed that Kev would join David and I. With plenty to look forward to, we planned to set off bright and early.
Pennington Marshes form part of the extensive Lymington and Keyhaven Marshes on the Hampshire coast, a mixture of grazing marsh, saltmarsh, mudflats and saline lagoons that is renowned for its birdlife. One of the most productive areas is Fishtail Lagoon, which lies immediately inside the sea wall and can be viewed from the Solent Way. A large island in the centre provides a nesting site for birds such as avocets, while the shallow margins of the lagoon can attract a variety of waders, wildfowl and terns. With its combination of muddy edges, shallow water and surrounding marsh, Fishtail is also the sort of habitat that can produce scarce passage waders, making it an obvious place to check during likely passage events.
We stopped for a comfort break and a spot of breakfast before deciding whether to make a detour to look for a Lapland bunting before heading on to try for the semipalmated sandpiper. With no report available yet to guide us, we decided to make our way straight to the rarer species.
We arrived at the car park to find it already full, but fortunately there was just enough room to pull in at the side of the road while still allowing other vehicles to pass. There was also good news on the BirdGuides news service confirming that the semipalmated sandpiper was still present, so we hurried from the car park towards the sea wall to see if we could connect with the bird. Having already been flushed from the pools on two previous occasions/days, once by a sparrowhawk and once by a peregrine, there was certainly no guarantee that it would still be there - it had gone awol for 4 hours the previous day.
As we approached the sea wall, we spotted what looked like our bird in the shallow pool and, sure enough, a few people were already taking photographs. Within a couple of minutes, another small wader joined it, but both birds suddenly took to the air and flew away towards Butts Lagoon. Apparently, a peregrine had been seen back towards the car park, which may well have been the reason for their sudden departure. After such a promising start, we were going to have to check that the semipalmated sandpiper was still there. Thankfully, we needn’t have worried, as it was soon located at the back edge of the water on Butts Lagoon, where it was associating with a little stint. Kev picked up a bearded tit after hearing it call, although Dave and I couldn’t manage to get onto it. We all did, however, get good views of a Cetti’s warbler as it called and then relocated nearby.
We followed the two birds as they fed, occasionally chatting with each other and with a couple of the birders nearby, until they suddenly got up and relocated back into Fishtail Lagoon, this time further along the sea wall. We followed a group of birders ahead of us along the lower path beneath the sea wall and soon found the birds feeding much closer. We all crouched down to get views through and over the fence, with the two birds still largely associating with one another. For me, the best photographs were those that captured the reflections in the still water. As we watched the birds, we were joined by Trevor Ellery @ElleryTrev16932, who had made the journey back after returning home the previous day when it appeared that the bird had departed. Having heard the news that it had returned, he was back again and had managed to catch up with it.
The semipalmated sandpiper is a scarce North American visitor to Britain, with most British records occurring during the autumn migration period. Although it occurs regularly enough to be firmly established on the British List, it remains a bird that most birders will encounter only rarely - the first documented British record was in Norfolk in 1953. This individual was a juvenile, its fresh, neatly patterned upperparts giving it a distinctly scaly appearance, contrasting with its clean white underparts.
From time to time, I found myself following the little stint as the two birds worked their way along the water’s edge, generally feeding from left to right, with one sometimes taking the lead before the other caught up. The little stint appeared smaller than the semipalmated sandpiper, with a tiny, fine black bill and dark legs. Its upperparts were intricately marked, with pale feather fringes creating the distinctive pale lines, or ‘tramlines’, down the back, while the underparts were clean white. It moved quickly along the water’s edge, constantly feeding, running a few steps before stopping to pick at the muddy margin. Having the two birds together made the difference in size and structure particularly obvious, although both were remarkably small waders.
I turned to rejoin Kev and David, only to find Kev chatting with Alan Boddington @alanbodd, a birder from nearby us in Warwickshire who we regularly bump into around home, as well as at birding sites further afield. It’s always good to see a familiar face further from home, and after catching up for a while, Alan headed off to get some closer photographs and videos of the birds.
On the Solent side of the sea wall we could see so many grey mullets, some adults and some fry. They can often be seen moving through the shallows or breaking the surface as they feed. The extensive network of tidal creeks, lagoons and mudflats around Lymington and Keyhaven provides ideal habitat for fish, and the abundance of marine life is one of the reasons the area attracts such a wealth of birdlife. The Isle of Wight provides some shelter from the full force of the English Channel, allowing fine sediments to accumulate and creating the shallow, productive waters and mudflats that are characteristic of the Solent coast.
After a quick discussion, we decided to move on and head for Stanpit Marsh, as the latest reports were still negative for the local Lapland bunting near Southampton. When we reached the car park to leave, we found Nick @old_caley and Anne Truby just arriving and parking up. We offered them our spot, as the space they had managed to find was particularly tight, making it difficult for cars parked opposite to manoeuvre out. This meant a quick repack of the car and a brief chat with Nick and Anne before we set off again. It was then that we discovered the phone signal was rather patchy, and eventually we had to rely on Kev’s phone to get us the directions we needed.
Stanpit Marsh lies at the northern end of Christchurch Harbour, where the Avon and Stour meet before making their way out towards the sea. The reserve is a mixture of saltmarsh, reedbeds, wet grassland, pools and tidal creeks, with the changing water levels constantly altering the appearance of the site. It is a particularly good place for waders, with the muddy margins and shallow pools providing feeding habitat for both resident birds and migrants.
The views across the marsh are extensive, with Christchurch Harbour and Hengistbury Head providing a backdrop beyond the pools and channels. At the right time of year, the open habitat can produce a good variety of passage birds, while the reedbeds and surrounding scrub add the possibility of something different. Like many coastal sites, Stanpit is a place where patience can pay off, with the birds often spread across a surprisingly large area and conditions changing as the tide moves through the harbour.
We joined a large group of birders gathered at the BCP Raptor Watch, who initially had their attention focused away from the Solent as they followed a glossy ibis moving around the marsh. We soon discovered that the largest contingent were members of the Christchurch Harbour Ornithological Group (CHOG), who were on an organised visit. We were told that the pair of white-tailed eagles had arrived at around 9.30am and had already spent at least ninety minutes on the East Marsh.
With David regularly taking to the water in his kayak, we were aware of the presence of several kayakers inside the yellow buoys around Stanpit and that they could potentially cause some disturbance. The eagles, however, appeared completely unperturbed, remaining settled on the marsh and occasionally preening.
The white-tailed eagles are part of the ongoing reintroduction programme on the Isle of Wight, where young birds collected from wild nests in Scotland have been released since 2019. Once released, the eagles roam widely as they learn the landscape, and Christchurch Harbour has increasingly become a regular destination for some of them. Individual birds have been recorded around Stanpit for several years, with a pair now making increasingly regular visits to the harbour and surrounding marshes. The presence of the pair was therefore no longer quite the unexpected event it would once have been, although seeing two of Britain's largest birds of prey settled together was still an impressive sight.
Although there was a significant amount of heat haze, views through the scope were still good, and we were able to share them with a couple of people who had either binoculars or cameras but not both. The haze is particularly noticeable in the videos below and reflected the conditions, with the day feeling more like the height of summer than late September.
We were scanning the marsh and out on the water when a shout went up that the eagles had taken off - we'd missed that. They flew along the channel in front of the houses, and you could see residents and birders watching them from the opposite side. Now in the air, their sheer size became even more apparent. They flew with broad, powerful wings held almost flat, the long, wide wings and projecting head giving them a very distinctive silhouette. Their flight was surprisingly effortless for such large birds, with long glides punctuated by slow, deep wingbeats. As they circled over the marsh, their white tails were clearly visible against the darker plumage, while the sheer breadth of their wings made them unmistakable even at distance. Watching the pair together, effortlessly gaining height before gliding over the marsh and the harbour, was an impressive sight.
They eventually climbed high enough that taking any more photographs seemed rather pointless, so we resumed scanning the waders around the water’s edge, across the marsh and along the field margins. There were good numbers of little egrets, with more than 20 present, along with at least nine grey herons, most of which were roosting rather than feeding. The grassier areas held plenty of curlews and bar-tailed godwits, giving us plenty to keep checking through as we continued to scan the marsh.
Overhead a glossy ibis flew by giving great views and is apparently a new arrival at the site that day. The glossy ibis has become an increasingly familiar sight in Britain. Once a genuine rarity, its numbers have risen considerably since the turn of the century, mirroring a major expansion of the species across western Europe. The first confirmed British breeding took place in Cambridgeshire in 2022, when a pair successfully raised a chick, and the species is now regarded as a colonising breeder.
The scale of the change was highlighted dramatically in September 2025, when an unprecedented influx saw hundreds of glossy ibises arrive across Britain and Ireland. With birds now being seen regularly at wetlands across the country, encounters with them no longer carry quite the rarity value they once did, although seeing them remains a memorable part of any visit.
We had already seen a single osprey pass through earlier, followed by a couple working their way up and down the coast. As we turned and started back towards the car park, however, one returned and, rather than simply passing through, appeared to be actively fishing offshore. We made our way back to our original position and watched as it worked steadily further from the shore, searching the water below.
Then it suddenly dropped into the sea. When it emerged, it was carrying a fish, and fortunately it began flying back towards the shore, giving us several passes as it carried what appeared to be a grey mullet. It looked to be a sizeable fish, and the osprey seemed to be working hard to carry it towards the coast, occasionally being mobbed a a couple of gulls.
With autumn migration well underway, the ospreys won't be staying for much longer. Having spent the summer in Britain, they will soon begin their journeys south, eventually reaching their wintering grounds in West Africa. In Hampshire, ospreys can remain into October, so the birds we were watching at Stanpit were taking advantage of the rich feeding opportunities around the harbour before setting off on their migration.
We prepared to leave, and from where we stood, as well as along the walk back, we picked out a selection of smaller birds including pipits, linnets, reed buntings and stonechats.
As we passed the Visitor Centre, we looked back towards the marsh and Kev pointed out a sun halo above us. A large, faint ring of light surrounded the sun, suspended against the sky. It is apparently caused by sunlight passing through millions of tiny ice crystals in high, thin cloud, with the hexagonal crystals refracting the light to create the circular halo. The effect was surprisingly obvious, occasionally showing a hint of colour around its inner edge. Against the intense late-September sunshine, it added another striking feature to a day that had already felt more like midsummer.
Kev was already armed with an explanation of how it formed, having read about sun halos recently.
We made it back to the car and discussed what to do next, conscious that the Lapland bunting had still not been located. Our friend Bryan Manston had warned us that there could be traffic problems on the route back, suggesting that travelling via Salisbury might be the better option. With that in mind, we decided to head through Wiltshire and make a stop at RSPB Winterbourne Downs, where we could try for some stone curlews. David had never seen one, so it seemed like a worthwhile addition to the day.
We arrived at the site and parked up where we had earlier in the year and set off up the track to view across the fields. The site was a complete change of habitat from the coastal marshes we had left behind. The reserve sits within the rolling chalk country of Wiltshire, with wide, open fields of restored chalk grassland stretching across the downland. Formerly agricultural fields, much of the site has been transformed into wildlife-rich grassland, with fallow plots and areas of sparsely vegetated ground providing the open, bare conditions favoured by stone curlews.
By late September, the site has taken on its autumn character and was very different from the habitats we had encountered earlier in the day. The grassland looked dry and somewhat parched beneath the strong sunshine, while the open landscape was broken by hedgerows and substantial areas of scrub. The carefully managed plots provided ideal habitat for stone curlews preparing for their autumn migration, but the birds could be remarkably difficult to pick out, even when they were standing in the open only a short distance away.
Initially, we began to doubt whether we would find any, but then, in a green crop in the distance, we spotted one, then a second and then a third. Through the scopes we could make them out, although they were distant and the heat haze was very strong. As we continued scanning the area, the number steadily increased until we had counted 17 individuals. We could also occasionally hear others calling from the field on the other side of the trees, although the ground there was almost completely covered in scrub and there would have been little chance of seeing them. How many are present is unknown but the 17 is very much a low estimate.
The latest RSPB article, published 25 September, confirms that the reserve had eight breeding pairs in 2026, but doesn't give the September post-breeding total. Interestingly, an RSPB local-group page says 30+ stone curlews have been seen at Winterbourne Downs in recent years so there could be many more than those we saw.
We packed up and made our way back to the car, bringing what had been a fantastic day of birding to an end. It had been a rewarding trip, with plenty of memorable birds, some excellent views and a good mix of species including a new bird on my year list. The drive home was thankfully straightforward, and we made good time, giving us plenty of opportunity to reflect on everything we had managed to see during a very enjoyable day out.
Year list: 294.
