Just passed NP hide a darter perched up nicely and the all black legs, waisted abdomen and reduced black and yellow patches on the thorax confirmed it as an immature male Ruddy Darter, a patch tick.

A little further along the path to Gv Marsh an immature male Broad-bodied Chaser was on patrol giving me my second dragonfly tick of the day.

The two well advanced Lapwing chicks were on Gv Marsh although I couldn’t find the younger chicks I had seen in the last week or so. A Brown Hare appeared close by as I watched the Lapwings.

Slightly unexpected was the group of 14 Black-tailed Godwits which flew over Gt Marsh as I arrived. The Lesser Whitethroat which is nesting here was alarm calling incessantly but I managed only a brief glimpse.

There were lots of Bombus lucorum/terrestris workers on the Stonecrop flowers but the Red-tailed Bumblebee (Bombus lapidarius) on the buttercups was a new species for the patch.

An hour of scanning around Gt Marsh produced no sign of Little Ringed Plover chicks or adults, very depressing. There were plenty of agitated Black-headed Gulls and Avocets circling overhead and in total I counted 10 Black-headed Gull chicks and seven Avocet chicks. Although I had managed views over most of Gt Marsh I thought I’d try the raised view over the Marsh from the sea bank. From this excellent vantage point I was delighted to see both of the Little Ringed Plover chicks with one of the adults close by. What a relief!

Azure Damselfly

Just before getting back to the car I checked S Hide Ditch to see the familiar Blue-tailed Damselflies lifting up as I approached and two male Azure Damselflies were new. An Emperor Dragonfly draped itself down from the rushes but was quick to dash up vertically to meet another male Emperor which flew too close.

At the sailing Club the 23 year old Oystercatcher was preening in the seaward side creek and a Gannet was a slightly unexpected find on the flat calm balmy Solent. The Ringed Plover who nested on the road side has finally hatched the eggs and the young have been walked away on to the saltmarsh. This is a real triumph of tenacity for the parents as the nest location meant that they had spent most of the last three weeks dashing to and from the nest as people and cars came close by. 

It’s possible that the Little Terns we have been seeing recently towards the point may be nesting on the shingle. Adam flushed one on his way back from his walk onto G Island last week and I also noticed in the log book that Brian and Val had seen a pair feeding from the point on Thursday. I decided to spend an hour or so looking for them at the Warden’s Hut but unfortunately no luck although the heat haze made things very difficult and distant terns were difficult to identify.

Mute Swan

On my walk across to the hides an alarmed Little Ringed Plover called loudly as it flushed up from the water’s edge next to the boardwalk bridge. I’d scanned the area before I’d approached but obviously missed it. It is probably one of the adults from Gt Marsh even though that is nearly a mile away. On the 3rd June I had seen one of the adults as it flew over my head calling at the eastern end of Gv Marsh, this was probably the same adult moving back to Gt Marsh from the boardwalk bridge.

From the DL’O screen I could see 2 Shelduck chicks with adults on B Water and then on DL’O scrape there were another 14 Shelduck chicks, they formed a long line following the adults towards the sluice gate. After five or six further scans I decided that there were three Avocet chicks on DL’O. Unlike Gt Marsh the chicks on DL’O never seem to get any bigger which unfortunately means that the Great Black-backed Gulls are picking them off fairly quickly.

From the JV side of B Water a Red Kite floated over the Gins, the Oystercatcher chick was still following the parents on JV Island and there were eight Egyptian Goose goslings poking their heads above the long grass on G West.

Seven Tufted Duck including five males appear not to be breeding unlike the Pochard pair who still have three ducklings following them everywhere.

A teneral female Common Darter rose up from the rushes near the boardwalk and landed in the long grass to harden her wings. The adult Lapwings were calling anxiously overhead and so the chick I saw here last week may still be present but I couldn’t see it. The Lesser Whitethroat was still singing from the Viewing Gate area.

There were lots of juvenile birds on show today including Dunnock, Linnet, Blue Tit, Starling, Pied Wagtail, Blackbird and Coot as well as Little Ringed Plover and Lapwing.

Painted Lady

Butterflies included at least four Painted Ladies, a newly emerged Meadow Brown which was new for the patch, several Red Admirals, 7 Small Heaths and a Speckled Wood

As I headed home I paused at the Reedy Ditch where there were an amazing 45 Greylag goslings.

Adam asked if Miranda and I could help Graham Giddens ring the Black-headed Gull chicks on the rafts out on DL’O lagoon. Our role was to count the chicks, estimate the remaining live nests and eggs, rescue any chicks that managed to jump over the chicken wire and all the while avoid falling over in the sludgy mud which sucked your boots whenever you moved.

Black-headed Gulls are an important breeding species in the Solent and they formerly bred in much larger numbers on G Island. It was a privilege to be so close to these birds and Graham ringed them as a quickly as possible to avoid upsetting them too much. The adults soon returned as we waded away from the rafts. There were 76 chicks of which Graham ringed the largest 41.

While there I also noticed a Common Blue butterfly in front of DL’O hide and an Emperor Dragonfly was in Spring Meadow as I drove past.

I relocated last week’s colour-ringed Oystercatcher and was able to get a better view of the ring on the left tarsus. It was definitely a double yellow ring thus confirming this bird as at least 23 years old. Pete Potts ringed it as an adult at Hamble Point on 28th Dec 1999. It winters near Hamble Point which is 9km away and feeds on wet fields near Pete’s bungalow at Chilling. Mine is the first breeding season sighting in all this time.

Oystercatcher at least 23 years old

The Ringed Plover at the Sailing Club was still sitting on four eggs next to the track. Given the perilous location they have been on and off the eggs countless times and so I hope the eggs have not become too chilled despite the adults amazing persistence.

The Sailing Club Oystercatchers were also still sitting on eggs.

Three more Avocet chicks had hatched on Gt Marsh to join the two well developed ones. There were still four on DL’O scrape of which I think one is from the first brood and three smaller birds from the second brood.  

Avocet

The Reed Warblers which are nesting near the B Water gate had successfully fledged at least three young.

On JV a female Pochard was accompanied by three small ducklings, successful breeding was only confirmed from three sites in Hampshire in 2019.

Pochard and ducklings

A Sparrowhawk dashed across W Lane closely followed by a squawking Jay, the first I’ve seen (as opposed to heard) this year. A ‘teenage’ group of nine 1st summer Mediterranean Gulls dropped onto B Water for an evening freshen up.

On the insect front I recorded Peacock, Small Copper and Green Hairstreak and I noticed in the log book that someone had seen seven Common Blues although I’m not sure where they are on the reserve. They need Bird’s-foot Trefoil as their food plant and this flowers on the Flooded Fields near the boardwalk but there was no sign there.

A Common Carder Bee (Bombus pascuorum) is perhaps the commonest bumblebee in the UK but the worker nectaring on Common Vetch was the first I’ve seen at NO. Lots of bumblebee workers were busy on the large carpets of Thrift. The narrow brown band at the base of the white tail and the golden (as opposed to yellow) thorax and abdomen bands suggest that this is a Bombus terrestris worker and not Bombus lucorum. The males, which join the workers later in the month are much easier to separate from each other.

Others flowers included Sea Campion, Common Vetch, Sea Beet, Ragged Robin, Silverweed, Heath Bedstraw and Lesser Stitchwort

On the sea there was a reasonable movement of terns heading west. A single Little Tern, five Common Terns and 10 Sandwich Terns, several of them carrying sand eels back to the 60-pair colony near Keyhaven. There was also a slightly bizarre very thick-billed Sandwich Tern which raised my heart rate for a while.

There were six new Black-headed Gull chicks on Gt Marsh and an unseasonable Black-tailed Godwit was feeding with the Avocets. Unfortunately the Little Ringed Plover chick numbers were down to two.

A Nightjar churred briefly somewhere on Gv Marsh and as darkness fell several Soprano Pipistrelles and Common Pipistrelles accompanied me on the walk back along W Lane.

Later – bad news from Adam’s beach walk the next day, Tuesday 8th. No sign of Peregrine eggs or chicks. Perhaps the 70 mph gales on the 21st May had taken their toll, Adam said the layout of the nest site and the tide lines had changed since we visited last, very depressing.

Thursday 3rd June 2021

As predicted by Adam the Little Ringed Plover chicks had been guided down to Gt Marsh and I found them on the mud on the southern margin. The tiny white chicks were feeding at the water’s edge but would occasionally dash back to Mum when they lost confidence or perhaps when she called them. They would then spend a few minutes sheltering under her.

The two fairly advanced Avocet chicks on Gt Marsh were still around but no new chicks yet from the other five sitting birds. The four Lapwing chicks were still on Gv Marsh. I was several hundred yards back towards the car when a calling Little Ringed Plover flew overhead. No doubt one of the parent birds returning to help with the chicks on Gt Marsh.

I met up with Dimitri and on the walk back a Whimbrel gave a snatch of song. On DL’O there were 10 Shelduck chicks, the first I’ve seen and also four young Avocet chicks. 18 Great Black-backed Gulls were nearby, way too many for the various chicks to have an easy time. From the screen I counted 18 Black-headed Gull chicks on the rafts, it looks like the Common Terns have had to try elsewhere.

On the other end of B Water, behind JV Island, there was a single Oystercatcher chick and a Cuckoo which had been calling for an hour or more was joined by a second bird and together they flew across the water in front of us. Two tiny new Lapwing chicks were also on Wigeon Fields and another newly hatched chick was on G West.

Perched on a dead tree at the back of B Water a Hobby surveyed G West and Wigeon Fields probably watching for hirundines, dragonflies or damselflies. Hobbies are probably breeding in one of the woodlands on the Estate.

I’d arrived at NO at 3:30pm so that I could finish with an evening visit to P Shore. I ended up spending four hours at P Farm hoping to see or hear Little Owls. As sunset approached I watched a White Wagtail feeding with the cattle and after sunset I began to record whatever bats were flying. There were Common Pipistrelle, Soprano Pipistrelle and Noctules.

White Wagtail

Other than a Tawny Owl calling from the woods at just after 10pm it was all quiet on the owl front. At 10:54pm and just as I was thinking about heading home I did hear another owl but it was the screech of a Barn Owl.
