I was meeting Ian here to catch up with the Purple Sandpipers that frequent the rocks and sea weed around the sea wall at Southsea castle. Something we only seem to do at the start of the year, a one off pilgrimage. As we walked along the promenade towards the area where they normally can be seen it was empty save for a Rock Pipit calling in the gloom and offshore a couple of passing Shags, a welcome year tick.
We walked along the promenade scouring the rocks and sea wall but there was nothing other than a few feral pigeons. We walked to the end of of the promenade and then back, a couple of Shag flew past once again, additional to the earlier birds, that made four in all, Shag appear to be regular here and replace the cormorants that probably move inland for an easier meal. The light was a little better now.
One settled in the water, the distinctive snake like head and neck appearing above the waves.
We walked back in the direction of the pier, and debated checking there for the sandpipers as they may have roosted there, we also tried to check the area below the sea wall but the sea weed made it very slippery. A Rock Pipit flew in and checked the edges of a puddle for any chance of food.
Calling above the noise of the crashing surf.
We continued the search, walking back around the castle once more. As we reached the end of the curve as the sea wall winds around the castle I noticed movement below on the rocks. There was a procession of waders coming towards us, where they had come from we had no idea. It was as if a trap door had opened and they had been sent out to go about their business. As they moved towards us I counted nine, but it turned out later as they flew out across the sea there were in fact ten present. Here there are six having moved from the dry rocks into the sea weed to forage at the edge of the surf.
We settled down as close as we could safely get and sat on the iron bars to watch as the Purple Sandpipers moved in and out of the surf, while trying to keep out of the wind amongst the rocks and concrete.
Not only were they busily foraging amongst the sea weed and keeping away from the tumbling surf, there was also the need to keep a look out above, danger could come from anywhere.
The Purple Sandpiper is a medium-sized wading bird, slightly
larger, stockier and darker than a Dunlin. Despite its name, it appears mostly
slate-grey in winter, with only a faint purplish gloss, and shows no purple at
all in breeding plumage. It has a slight
down-curved beak and distinctive short bright orange legs. In flight it shows a
thin white wing-stripe on otherwise dark wings.
Three separate populations of Purple Sandpiper winter in
Britain and Ireland, those in the north and west originate from those breeding
on northern tundra on Arctic islands
in Canada and from coastal areas in Greenland, and those
wintering in eastern and a few in southern England, from northeast Europe in Scandinavia and Svalbard.
These birds forage on rocky coasts, picking up food by sight. They mainly eat arthropods and molluscs, also
some plant material. One of the main staples are insects known commonly as
"seaweed flies" because they feed, mate, and create a habitat out of
beached seaweed which is common near the Purple Sandpiper's habitat.
The flock would move between spending time foraging amongst the sea weed and digging deep into the cracks in the concrete and resting out amongst the rocks. When still and hunkered down close to the rocks it was difficult to pick them out.
When foraging they are busy little birds and totally approachable, the only thing that prevented us from getting closer was the slippery rocks, neither of us was looking for an early morning dip!
This lack of fear of us was tested as a large labrador dog came bouncing down the sea wall, past us and into the middle of the flock, at one point I thought the dog was going to grab one in its mouth but they flew off in time out over the sea. They flew around and came back towards us, but veered off to the right heading over the rocks and away out of sight. We looked for them again but couldn't find them, maybe they had returned to safety through the trap door!
So it was farewell to Southsea's Purple Sandpipers for another year!
Up on the sea wall we met an old gentleman who was feeding the foxes in the castle moat. There were three foxes, and all of differing condition, one large male with a thick brush, a smaller individual, probably a vixen, and this one with a very mangy tail.
The old gentleman is regular here, and as well as the foxes will feed the crows. Everywhere he went the crows would follow, there were four of them and they would perch on the wall and fence as we stood talking to him allowing the opportunity for some lovely portraits against the grey sky.
Extremely intelligent birds.
FRom Southsea we headed west back towards Porchester and the area of Wicor Lake. Here we were hoping to catch up with a Scaup and Great Northern Diver that had been present all week. On arriving the weather decided to go against the forecast, and there were waves of heavy drizzle pouring in and along with a now quite strong south westerly wind it made visibility very difficult. There was a large flock of Redwing feeding on the open grass alongside the shore, with Goldfinches and Bullfinches in the bushes. Out on the water though there was very little with most of the duck, Wigeon and Shelduck on the far side sheltered from the wind.
There was no sign of the Diver or Scaup, and only a couple of Great-crested Grebes. With the tide high there were flocks of waders wheeling around looking for a dry place to roost. On the islands there were large numbers of Oystercatchers and in the air a few Dunlin, and a large flock of around 300 Golden Plover.
We walked around to Cams Lake in the hope that the shelter would support some more birds but we could only find a few Red-breasted Mergansers. A first visit to this spot was not celebrated with success. The drizzle looked like it would be moving away east, and we decided to head that way too, this time to close the county border at Warblington, there our quarry were the Cattle Egret that now seem to be resident.
As we drove towards the church on Church Lane I noticed that I had lost Ian, turning around I found him pulling his camera out of the van, the Cattle Egret were in the field along with Little Egrets and of course some cattle.
The cattle egret is a cosmopolitan species
of heron found in the tropics, subtropics, and warm-temperate zones. Originally native to parts of Asia, Africa,
and Europe, it has undergone a rapid expansion in its distribution and
successfully colonised much of the rest of the world in the last
century.
Cattle egrets exploit drier and open habitats more than
other heron species. Their feeding habitats include seasonally inundated
grasslands, pastures, farmlands, wetlands, and rice paddies. They often accompany cattle
or other large mammals, catching insect and small vertebrate prey
disturbed by these animals.
The cattle egret has a relatively
short, thick neck, a sturdy bill, and a hunched posture. The non-breeding
adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During
the breeding season, adults develop orange-buff plumes on the back,
breast, and crown. The positioning of the egret's eyes allows for binocular
vision during feeding and physiological studies suggest that the species
may be capable of crepuscular or nocturnal activity. Adapted to
foraging on land, they have lost the ability possessed by their wetland
relatives to accurately correct for light refraction by water.
The cattle egret has undergone one of the most rapid and
wide-reaching natural expansions of any bird species. It was originally native
to parts of southern Spain and Portugal, tropical and
subtropical Africa, and humid tropical and subtropical Asia. At the
end of the 19th century, it began expanding its range into southern Africa,
first breeding in the Cape Province in 1908. Cattle egrets were
first sighted in the Americas on the boundary of Guiana and Suriname in
1877, having apparently flown across the Atlantic Ocean. In the 1930s, the
species is thought to have become established in that area. It is now widely
distributed across Brazil.
The species first arrived in North America in 1941
(these early sightings were originally dismissed as escapees), bred in Florida in
1953, and spread rapidly, breeding for the first time in Canada in
1962. It is now commonly seen as far
west as California. It was first recorded breeding in Cuba in
1957, in Costa Rica in 1958, and in Mexico in 1963,
although it was probably established before then. In Australia, the colonisation began in the
1940s, with the species establishing itself in the north and east of the
continent, with them regularly visiting New Zealand in the 1960s.
In Europe, the species had historically declined in Spain
and Portugal, but in the latter part of the 20th century, it expanded back
through the Iberian Peninsula, and then began to colonise other parts of
Europe, southern France in 1958, northern France in 1981, and Italy in
1985. Breeding in the United Kingdom was recorded for the first time
in 2008, only a year after an influx seen in the previous year. In 2008, cattle
egrets were also reported as having moved into Ireland for the first
time. This trend has continued and
cattle egrets have become more numerous in southern Britain with influxes in
some numbers during the nonbreeding seasons of 2007/08 and 2016/17. They bred
in Britain again in 2017, following an influx in the previous winter, and this
has continued with Cattle Egrets breeding in more counties, including Hampshire
in 2019.
The massive and rapid expansion of the cattle egret's range is
due to its relationship with humans and their domesticated animals. Originally
adapted to a commensal relationship with large grazing and browsing
animals, it was easily able to switch to domesticated cattle and horses. As the
keeping of livestock spread throughout the world, the cattle egret was able to
occupy otherwise empty niches. When I have seen them in India they have also learnt to exploit man, hanging around markets and open air food stalls
There were five present here at Warblington. Last year a pair bred but I am not sure how many fledged, two of these birds were showing signs of developing the orange buff breeding plumage on the crown and breast, while the others were mostly white. The adult birds also appeared to chase off the other birds, maybe these were that family.
They fed with the Little Egrets but the style was very different, they walk with a bobbing action and look much smaller, while the Little Egrets appear much more elegant.
There is also a good number of birds at Sidlesham, and there may be movement between the two areas. There have been reports of eight and nine feeding here which but five appears to be the consistent number. It could be a result of misidentification or maybe birds coming over from West Sussex.
We had found a hole in the fence that allowed us to watch them close up, but as the cattle came closer they flew to the other end of the field and this required other means to try and photograph them.
They eventually all fed together but at the back of the field, here three together.
While this is a distant view of all five, the bird on the far right is a Little Egret.
While watching the Cattle Egrets there were tits in the hedgerow and a female Sparrowhawk put up everything as it cruised over the field.
After some lunch we decided to head back west and parking just off the Langstone bridge in the Ship Inn. From their we crossed the bridge and walked to the Oyster Beds. It was very quiet everywhere. Around the beds were a few Brent Geese and Oystercatcher and Curlew, but no duck what so ever. The tide was high and the wind very strong. A scan of the sea did not even produce a Great crested Grebe, so we missed out on the Black-necked Grebes reported in the week. A Greenshank was roosting along with Turnstone on one of the islands in the lagoons, and there were four pairs of Red-breasted Mergansers, this drake being very close in for once.
The trick was to wait for it to dive, and then try and get closer. It worked for a couple of dives then it headed out to the open water.
We headed back across the bridge and were stopped by a smart Common Gull in the water close in.
It took to the air and gave some close views and a chance for some aerial shots in the afternoon sunshine that had just appeared.
Common gulls have that dove like appearance, maybe not as much as the Kittiwake but enough to make them presentable. It used the strong wind to hold it up as it dropped into the water.
we crossed the bridge in sunshine and took the path to Southmoor. Here we hoped that the reported Short-eared Owls would find some sheltered spots to hunt later in the afternoon. First though we walked around the sea wall where there were some ducks on the sea, Gadwall, Wigeon Pintail and a single female Goldeneye. We could not find the reported Long-tailed Duck though, once again further out there was very little if anything on the water.
The path leads around in a loop and passed a gravel pit where there were Teal, Gadwall, Shoveler and Mallard. We made our way to the two fields where the owls have been reported from. We set ourselves to wait, and wait we did. The time dragged on, the wind remained strong and the light became increasingly gloomy. As the clock passed four o'clock we decided that they were not going to show, if they did there would be no chance for any photos so we decided to call it a day and head back to the cars.
Not a bad day, and despite the gloomy conditions some great photographs of the Purple Sandpipers and the Cattle Egrets. The year is up and running with plenty more opportunities, we hope.
