Gibraltar Point Bird Observatory Blog: Early September 2024

September 10th. Cloudy and overcast with a strong westerly wind, then light rain in the afternoon.

A morning sea-watch/vis migration session was undertaken from 0700-0900hrs, with highlights of 3 Black Terns and a Great Skua offshore, mixed waders arriving from the north including a Little Stint and overland passage of 400 Meadow Pipits, 5 Grey Wagtails, 15 Yellow Wagtails, 120 Swallow and 400 House Martins including a single flock of 190. The juvenile Hobby showed very well again in the East Dunes.

During the late afternoon from the Mere Hide there were 3 different Marsh Harriers seen flying south along with a Buzzard and a probably Honey Buzzard together flying west from the East Dunes. Meanwhile a Bearded Tit called briefly just after a heavy rain spell and a Kingfisher was present as well. On the water were 14 Tufted Duck, 14 Shoveler and 3 Pintail with 8 Little Grebe. At the back of the Mere was a Short-eared Owl hunting, whilst a skein of 150 Pink-footed Geese went south before turning out towards Norfolk.

September 9th. Cloudy, with some light morning and afternoon drizzle and increasing north-westerly wind.

The first Pink-footed Geese of the autumn were heard in the murky conditions in the morning, with a skein of 21 in the evening. A scattering of migrants around the Reserve included several Redstarts, Wheatears, Whinchats and Willow Warblers, with 5 Tree Pipits passing over, but no Flycatchers today. Other birds around included a Short-eared Owl, 3 Marsh Harriers, a Peregrine and 2 Hobby..

A wind-shortened morning ringing session in East Dunes resulted in 4 new birds: a Willow Warbler, a Robin and 2 Blackcap; and a retrap Robin.

An arrival of Convolvulus Hawkmoths involved at least 8 found around the Reserve.

September 8th. Soggy, cloudy start, gradually drying out and clearing, becoming warm and humid, with light to moderate south-easterly wind.

Generally quieter than yesterday with few signs of new grounded migrants. A Honey Buzzard was flying south along the Storm Ridge at 6.40am, later flying north up the East Dunes, presumably the bird that settled at the south end yesterday morning. A Hobby was on the beach. Two Ospreys passed through during the morning, with one heading off south-west and the later bird heading south over the beach and possibly out to Norfolk. A Wryneck was found mid morning (originally on the Heligoland Trap briefly, then towards Storm Ridge and not seen again).

A Marsh Harrier, 2 Hobby and at least 15 Common Buzzard also moved south as the day warmed up. There was a fair passage of up to 400 Swallows early morning, and a scattering of Redstarts, Wheatears (over 25) and Spotted Flycatchers, with fewer Tree Pipits, Whinchats and Pied Flycatchers. A Kingfisher was on a new artificial perch in front of Fenella Hope hide early morning whilst in the afternoon there were 26 Spoonbill there. Late on a Swift was over North car park as was a Pied Flycatcher whilst a Spotted Flycatcher was in the West Dunes.

A morning ringing session in the East Dunes provided 14 new birds: 3 Great Tit, 2 Robin, 2 Blackcap, 2 Whitethroat, 2 Dunnock, a Chiffchaff, a Garden Warbler and a Redstart; and 3 retraps: a Great Tit, a Dunnock and a Spotted Flycatcher.

September 7th. A very overcast start to the day with the cloud starting to break up later on somewhat. A hint of precipitation occasionally and a very light almost undetectable north-easterly breeze.

Starting with a wader roost of 100,000 birds, the day turned into a great one for migrants with news coming in from all over the reserve from first thing. A Wryneck was found by the northern boundary, whilst an Icterine Warbler was discovered near Mill Hill. Probably two different Honey Buzzards arrived today (compare photos below), with one seen passing over the south end of the reserve early and one seen on North Building Ridge perched occasionally and making short flights in the misty conditions. Early afternoon, a Barred Warbler was discovered on Rock Ridge which was still showing at 4pm at least.

Other migrant totals for the day, including birds ringed, were 25 Wheatear, 11 Tree Pipit, 12 Spotted Flycatcher, 15 Redstart, 7 Pied Flycatcher, 7 Garden Warbler and 10 Whinchat. Also around were 2 Peregrines together on East Dunes, 4 Marsh Harriers and a Short-eared Owl. From Harvey's Hide there were a Ruff, a Common Sandpiper and a Common Tern amongst other waders.

A morning ringing session in East Dunes produced 32 new birds: 2 Wren, a Wood Warbler, a Firecrest, 2 Garden Warbler, 5 Spotted Flycatcher, 4 Redstart, 3 Robin, 2 Blackcap, 3 Whitethroat, a Tree Pipit, a Pied Flycatcher, 3 Lesser Whitethroat, 2 Wheatear, a Blue Tit and a Whinchat; and 4 retraps: 2 Dunnock, a Long-tailed Tit and a Blue Tit.

September 6th. A bright start to the day with clear blue skies continuing through the day, becoming warm despite the increasing north-easterly wind.

A Convolvulus Hawkmoth was trapped at Sykes Farm overnight.

At least 15 Wheatear were amongst birds on the reserve along with a Yellow Wagtail around the Wash Viewpoint, a Corn Bunting over the Ringing Hollow, 2 Pied Flycatcher, 2 Spotted Flycatcher and 3 Redstart in the Plantation and at least 4 Tree Pipit over, whilst a hunting Sparrowhawk was around East Dunes and an Osprey passed through.

The morning sea-watch was difficult in bright sunlight but three hours produced the following highlights; a Sooty Shearwater, 2 Manx Shearwater, 14 Arctic Skua, a Pomarine Skua, a Long-tailed Skua and 2 Great Skuas.

During the mid afternoon, it was apparent that the easterlies were starting to produce with new birds arriving, and there were totals of 10 Spotted Flycatchers, 18 Pied Flycatchers, and 12 Redstarts.

A wind-shortened morning ringing session in East Dunes yielded 4 new birds: 2 Wren, a Willow Warbler and a Dunnock; and a retrap Great Tit.

September 5th. Soggy start with increasing north-north-easterly wind, full cloud cover and occasional light rain/drizzle throughout the day.

Early news involved a Redstart and a Wheatear along with a general increase in Meadow Pipit numbers along the Storm Ridge. Meanwhile a Wryneck was re-located along the Cycle Track near the entrance to Harvey's Hide, and there was presumably another Wryneck next to Sykes Farm Track a short time later. During the course of the day there was a Pied Flycatcher opposite the gate to Jackson's Marsh and another one close to Mill Hill with the tit flock. A Redstart was at the north end of West Dunes whilst 2 Wheatear were on the East Dunes frontage and a Hobby was over the Ringing Hollow.

During the late afternoon, the Mere held 11 Little Grebe, a Pochard, a Gadwall, 5 Wigeon, 9 Shoveler, 20 Mallard, 62 Teal and 4 Tufted Duck. From Fenella Hope Hide on Tennyson's Sands, there were 35 Spoonbill, 202 Canada Goose, 203 Greylag Goose and 10 Little Grebe.

Highlights of a morning sea-watch included 2 Black Terns, 14 Arctic Skua and a Red-throated Diver north, and a Black-throated Diver, a Long-tailed Skua, a Manx Shearwater and a Bonxie south, whilst in the evening 4 juvenile Long-tailed Skuas, 20 Arctic Skua, 2 Sooty Shearwater, 2 Manx Shearwater, 3 Shearwater sp, 2 Fulmar, 170 Kittiwake and 240 Common Scoter were recorded. A Caspian Gull and a Merlin were on the beach.

A wind-shortened morning ringing session in East Dunes provided 2 new birds: a Robin and a Sparrowhawk; and 4 retraps: 2 Redstart, a Lesser Whitethroat and a Wren.

September 4th. A mostly sunny day with clear blue skies and an almost still day, with just a hint of a west-south-westerly wind, although clouding over later on with prolonged rain through much of the afternoon.

Early news involved the re-discovery of the Wryneck on the Cycle Track near the North Hide entrance from 7.20am onwards. Four Tree Sparrows were in the Visitor Centre Car Park before flying towards the Wash Viewpoint. Few Pied Flycatchers remained on the Reserve, but 3 Redstarts were seen at the north end of the West Dunes and 4 Wheatears were along the East Dune frontage. Swallows and martins were heading south during the morning with several Yellow Wagtails and a pulse of Meadow Pipits. A Kingfisher was on the Fenland Lagoon.

A morning ringing session in East Dunes produced 8 new birds: a Wren, a Willow Warbler, a Swallow, 3 Robin, a Blackcap and a Redstart; and 2 retraps: a Redstart and a Dunnock.

September 3rd. A very wet start with torrential periods of rain, staying cloudy for much of the day, with occasional rain and a light northerly breeze turning westerly later on.

Early news after the rain stopped involved a Red-breasted Flycatcher and a Wood Warbler with 2 Spotted Flycatchers and 3 Pied Flycatchers in the Pines by the entrance sign to the reserve. There was a good scattering of Pied Flycatchers and a few Redstarts elsewhere around the reserve. Presumably one of yesterday's Wrynecks was located on the path to the Mere at 12.40pm, with (presumably the same bird?) being relocated back on the Cycle Track at 4.40pm until at least 7.30pm.

Eleven Egyptian Geese were on Tennyson's Sands early on with a group of 32 Golden Plover which dropped in briefly on their way inland. Also on Tennyson's Sands early on were 441 Black-Tailed Godwit,1 Green Sandpiper, 2 Greenshank and 22 Dunlin, 22 Spoonbill.

Six Pintail flew over Aylmer Avenue during the afternoon, whilst 3 were on the Mere with other wildfowl later in the afternoon. Four Whinchat and 2 Stonechat were on ridges out towards the East Dunes during the day and a Water Rail family was showing well on Jackson's Marsh for much of the afternoon whilst a Garden Warbler was along the Cycle Track towards Harvey's Hide briefly later on during the afternoon. A Kingfisher was commuting between the Mere and Tennyson's Sands often visiting the Mill Pond. The Wood Warbler was seen again briefly in the afternoon a few hundred yards from where it had been originally assuming it was the same bird.

Tennyson's Sands held impressive numbers of birds during the late afternoon, including 276 Canada Goose, 101 Greylag Goose, 134 Mallard, 102 Teal, 42 Little Grebe, 4 Tufted Duck, 2 Water Rail and 14 Spoonbill. Waders were represented by 385 Black-tailed Godwit, 77 Lapwing, 35 Avocet, 4 Dunlin, 4 Curlew, 2 Ruff, 2 Oystercatcher, 2 Redshank, a Snipe and a Spotted Redshank. Hirundines included 400+ Swallows and 10 Sand Martins passing south over the Lagoons and Croftmarsh in a 20 minute period late afternoon.

September 2nd. Cloudy, misty, quite soggy start, rapidly clearing and drying out, becoming quite warm, with light north-easterly wind, and with the occasional shower in the afternoon.

Another highly entertaining day for observers on site in and amongst a raft of migrants. Highlights of the day were an Icterine Warbler early on around North Car Park. Three Wrynecks were found with the first discovered out from Mill Hill in scrub to the west. Early afternoon another Wryneck was discovered on the Cycle Track near to the entrance to North Hide and continued to show intermittently on the Cycle Track well into the late afternoon. A third Wryneck was discovered in scrub north of the Mere Meadow late afternoon showing at nearly the same time as the Cycle Track bird leading the observer to believe it was third bird.

Totals of other migrants on the reserve for the day were 31 Pied Flycatcher, 23 Redstart, 13 Whinchat, 3 Spotted Flycatcher, 2 Stonechat, 2 Wheatear, a Garden Warbler and 2 Tree Pipit (South). Seven Buzzard passed south over Sykes Farm and there was a noticeable increase of Robins and a light movement of Hirundines through the day, with 8 Swift south during the late afternoon.

Also during the late afternoon, Harvey' s Hide provided views of 414 Black-Tailed Godwit, 66 Golden Plover flying over with 47 dropping in to preen on their way to the Wash, 6 Ruff, 2 Dunlin, 2 Snipe, 2 Little Ringed Plover, a Green Sandpiper, a Spotted Redshank, 17 Little Grebe, 2 Marsh Harrier and 4 Kestrel.

A morning ringing session in East Dunes resulted in 11 new birds: a Pied Flycatcher, 3 Redstart, a Spotted Flycatcher, a Garden Warbler, a Robin, 2 Whitethroat and 2 Dunnock; and 3 retraps: a Redstart, a Dunnock and a Whitethroat.

September 1st. Mostly cloudy, with increasing north-easterly wind.

The day's recording started with a fairly routine if slightly disappointing sea-watch in respect of the conditions; a constant stream of northbound Sandwich Terns was mixed with Kittiwakes and Gannets and a single Black Tern, with flocks of Common Scoter totaling 246. In addition, there were 8 Arctic Skuas, 2 Great Skua, 5 Fulmar, 2 Red-throated Divers and an unidentified Diver.

On the beach, one of the regular Hobbys looked like it had roosted overnight. After a Redstart and a Pied Flycatcher had been trapped in the ringing area, it became apparent that new migrants were arriving from late morning and into the afternoon. Good coverage of the census area resulted in counts of 29 Pied Flycatcher, 10 Common Redstart, 5 Tree Pipit, 4 Spotted Flycatcher, 11 Wheatear, 9 Whinchat and a Goldcrest amongst a small arrival of warblers. The windy conditions making observations difficult away from sheltered spots. A group of 8 Buzzards were circling over the Reserve late morning and probably passed through, whilst highlights from the lagoons included a Curlew Sandpiper, a Great White Egret and 14 Spoonbill.

In the evening, attention turned to the sea again where passage was fairly similar to the morning but a Manx Shearwater passed through and the highlight was an adult Sabine's Gull, initially flying strongly north, but then pausing and blogging offshore for a while.

On the beach, numbers of large Gulls were building up and included 5 Caspian Gulls and 2 Yellow-legged Gulls. A Hobby was again harassing the smaller birds in the roost and was given some assistance from a Marsh Harrier.

A wind-shortened morning ringing session in East Dunes provided 3 new birds: a Chiffchaff, a Pied Flycatcher and a Redstart; and a retrap Dunnock.

Overnight, migrant moths trapped included a Tawny Wave.
