17th April. A calm and sunny start to the day that became progressively wintery; colder, windier, with cold rain showers and then thick hail! One Cattle Egret was around the lagoons in the morning before flying off inland. Other birds around included a Great White Egret, Peregrine, 2 Redwing and the regular Goldeneye. A Harbour Porpoise was offshore.

16th April. Strong west-north-west wind with occasional rain showers. Good visibility over the sea and again a fair number of Sandwich Tern, 4 Commic Tern (probably Arctic), 6 Fulmar, 6 Gannet and a Pintail. The highlight though was a close, southbound Bonxie. 2 Cattle Egrets were on the Old Saltmarsh, a Water Pipit was on Croftmarsh and the Goldeneye remained on Tennyson's Sands.

15th April. Strong south-westerly wind, with occasional rain, sometimes heavy. An hour's sea-watch before a heavy rain shower early morning was productive with 164 Sandwich Tern, 2 Arctic Tern, 7 Fulmar and 8 Common Scoter moving south with at least 400 Common Gulls. 2 Merlin and 2 Red Kite also moved south. A pair of Mediterranean Gulls were on Tennyson's Sands. Another 8 Fulmar went south in 40 mins late evening. 

14th April. A good migration of Finches and Corvids again and plenty of birds singing in the dunes this morning. Most of yesterday's Wheatears had moved on. Linnets were predominant on passage with good numbers of Siskin, Goldfinch, Chaffinch and Yellow Wagtail, with the first Tree Pipit of the year. A Spoonbill came in off the sea and circled high over the East Dunes whilst an Osprey also came in off the sea and went during a good raptor passage that included 6 Sparrowhawk, 3 Kestrel, 3 Marsh Harrier, 2 Buzzard and a Red Kite. The Glossy Ibis had returned to the Freshwater Marsh after its visit to Anderby and it was probably seen heading inland late morning. A Common Sandpiper was on the River, 55 Sandwich Tern moved south at sea and other birds around included Woodlark and Brambling.

A morning ringing session at Aylmer Avenue by Liam Andrews and Sam Goddard provided 2 new birds: a Cetti's Warbler and a Sedge Warbler; and 2 retrap Long-tailed Tits.

13th April. The weather was pretty much the same as yesterday. The main theme of the morning was an arrival of Wheatears with an initial wave of 10 birds, mostly on the seaward dunes but quickly moving inland to the West Dunes, with 5 being seen on Rock Ridge later, before another arrival of 22 along the beach and outer dunes including 13 together, again most moving quickly inland. A Ring Ouzel was another new arrival that quickly disappeared and there were several new warblers in including the first 3 Lesser Whitethroats of the year. 

Visible migration involved fair numbers of the regular Finches and Corvids with a scattering of Meadow Pipits and Yellow Wagtails and a Red Kite. A party of 16 Crossbill left the North Car Park Pines and headed south, and a group of 5 Greenshank arrived. At least 1 Woodlark was around the east side of the Reserve ranging over a large area.

 A morning ringing session at Aylmer Avenue by Mike Polling produced 2 new birds: a Chiffchaff and a Blackcap; and a retrap Sedge Warbler. 

 Green Hairstreak butterflies are now on the wing in the dunes.

12th April. A fine morning, dry with bright sells and a cool, increasing south-westerly breeze.  The migration of Finches and Corvids continued overland including 3 Jays and there were 3 Woodlarks today. One remained on the East Dunes from yesterday, another flew high south over the Freshwater Marsh and Old Saltmarsh and another arrived from the North and was vigorously pursued by a Merlin over the East Dunes. Fortunately for the Woodlark, the Merlin then became distracted by two passing Peregrines! - a pretty spectacular display all round ! The Glossy Ibis remained on the Freshwater Marsh floods with 15 Curlew, 25 Black-tailed Godwit, 250 Black-headed Gull, 4 Med Gull and a variety of dabbling duck. It was fairly quiet offshore, with a few Sandwich Terns and Common Scoter and a Red-breasted Merganser, but a southbound Black Tern was quite a spring rarity. A Great White Egret also flew south over the sea. Other birds around included Hen Harrier, Greenshank, 2 Grasshopper Warbler and a Water Pipit. After feeding well during the afternoon, the Glossy Ibis left the Freshwater Marsh, circled, gaining height and then left high north around 1720. Also at this time, several flocks of Curlew were leaving the Wash and flying out high north-east.

During the fine weather a range of insects were seen including several butterflies; Speckled Wood, Peacock, Small Tortoiseshell, Comma, Orange Tip, Green-veined White and Holly Blue.

11th April. A bright morning with a cool breeze initially but becoming quite warm. A fairly light early morning migration largely involved Siskins, Chaffinches, Linnets, Goldfinches and Corvids but a flock of Thrushes involved 5 Fieldfare and a Ring Ouzel and there were at least 2 Woodlarks, one moving south and another mobile around the Reserve in full song. A Ring-necked Parakeet was seen around the Plantation. Later in the morning raptors started to move, including 4 Common Buzzards, 2 Marsh Harrier, 3 Red Kites, 2 Kestrels, 6 Sparrowhawk, a Peregrine and a remarkable 7 Merlin. The Glossy Ibis was seen again around the Freshwater Marsh during the afternoon and early evening, where at least 9 Med Gulls were associating with the Black-headed Gulls. Yesterday's Common Redstart remained in the East Dunes, calling and singing regularly. Other birds around included Caspian Gull on the beach again and a Spoonbill.

Early April 2024

Access Update; Please note that the paths running seaward from both car parks are flooded after the surge tide on 8th April. 

10th April. A fairly dry morning with a mix of sunny and dull periods and with wind increasing to gale force again later ion the day. The Glossy Ibis remained around the Freshwater Marsh with a Great White Egret and a Spoonbill on adjacent lagoons whilst the high tide produced a minimum of 15000 waders at roost. Several Blackcaps and Sedge warblers were back, singing on territory with other new migrants including a Redstart and Stonechat in the east Dunes and a Fieldfare in the West Dunes. Corvids were prominent during this mornings vis mig which also saw 5 Red Kites pass through (including 4 together). 4 Water Pipits were mobile.

9th April. Banks of light drizzle passed through during the morning and there was heaver rain later with the southerly wind again increasing to gale force. Moving south during the early morning watch were Siskins and Chaffinches again with 12 Swallow, 2 Sand Martin, 2 House Martin, 2 Yellow Wagtail, 3 Marsh Harrier, a Buzzard and a Red Kite. A Common Whitethroat was singing in the West Dunes and a Sedge Warbler on Tennyson's Sands. Offshore, 300 Common Scoter and an early Little Tern flew south and a Caspian Gull was on the beach. The Glossy Ibis was relocated on the Freshwater marsh early evening and was subsequently quite mobile. Other birds around included 2 Hen Harrier, a Jack Snipe, 4 Wheatear and the regular Goldeneye.

8th April. A sunny morning with a moderate southerly breezeA further reduction in vis mig despite seemingly more favourable wind strength, but nonetheless still a fairly impressive movement for anyone who has not witnessed flocks of migrating finches at low level. A Twite was the highlight with 3 Bramblings, several Swallows, Yellow Wagtails and a Grey wagtail also moving and 6 Red Kites arrived from the north and passed through, including 4 together. A good arrival of Wheatears involved up to 15 along a short strip of coastal frontage, a Woodlark gave brief song near Mill Hill and a Grasshopper Warbler was reeling at the north end. 7 Water Pipits were commuting between the Fenland Lagoon and Freshwater Marsh. A Glossy Ibis flew low south-west at 1246 from the Freshwater Marsh area and somehow managed to elude most birders on site. However it came out of hiding early evening, when it undertook several flights before eventually settling on Croftmarsh, viewed from North Hide . A Spoonbill and 5 Med Gulls were around the lagoons, with a Common Sandpiper and a Greenshank new in. A Common Redstart was another new arrival in the West Dunes late afternoon whilst a Shorelark on the north saltings presumably remains from the small winter flock. The evening spring tide was increased by a predicted surge, producing an enormous tide. Over 20,000 waders were up at the high tide roost and 2 Ravens were settled on the East Dunes before heading north,

7th April. A very windy day with a Force 6 southerly, gusting 7-8, making bird recording hard work. However many birds were battling against the wind on migration. Siskins and Chaffinches again dominated the movement but amounting to less than half of yesterday mornings totals, whilst Linnets were better represented. A Serin was a surprise migrant and perched a couple of times on its way south, calling regularly. Two Woodlarks also moved through separately along with 40 Swallows, 5 Sand Martin, 5 House Martin, 6 Yellow Wagtail and 2 White Wagtail. Another 5 Sand Martin, a House Martin and 2 Swallows were hawking over the lagoons late afternoon. Brambling had increased to 4 at the Wren Woodland feeding station which also attracted several Siskins and 2 Crossbill coming to drink. 2 Wheatear remained at the north end and a Ring Ouzel was new in there too. 4 Med Gulls were on the Freshwater Marsh with 300 Black-headed Gulls. Birds of prey around included 2 Peregrine, 2 Merlin and the regular Hen Harrier whilst the first Arctic Tern of the year was offshore.

6th April. A strong southerly breeze, but without rain today and good visibility. A busy day for visible migration and the arrival of new migrants. Siskin and Chaffinch were the main components of flocks moving south, often at very low level in the strong wind. Interestingly, pretty much all the Chaffinches were noted to be females. Totals over 2.5 hours from 0645 were 1206 Siskin and 1536 Chaffinch. Surprisingly only 1 Brambling was picked up in the flocks but another one showed well in the Plantation. Three Crossbill, 13 Swallow, 2 House Martin, and 6 Yellow Wagtails also moved south with one of the latter apparently Blue-headed and a Raven headed inland. A Swift at the north end was an incredibly early arrival and 6 Wheatears were scattered along the length of the Reserve. Offshore, 2 Little Gulls and the first 2 Whimbrel of the year headed south and a Bottle-nosed Dolphin was also moving south. Other birds around included 3 Med Gulls ( a pair and a second summer, the regular ringtail Hen Harrier and 3 Merlin (2 hunting together).

5th April. Rain overnight persisted through much of the morning, although a break in the weather enabled some finch passage despite a strong southerly wind. Most records from the afternoon when a new Firecrest was found along the Sleeper Track in the East Dunes, the first Yellow Wagtail of the spring passed through with 3 Swallows and a Sand Martin, another 3 Sand Martins were hawking over the lagoons where the female Goldeneye returned and a Med Gull joined 200 Black-headed Gulls on the Freshwater Marsh. An evening seawatch recorded 15 Sandwich Terns and the first Common Tern of the year fishing and moving slowly south into the Wash. Birds of prey around included Peregrine and Barn Owl.

4th April. Overcast with a gentle south-westerly wind. A Great Northern Diver was seen distantly offshore and briefly settled on the sea. 2 Swallow flew north late morning, a Merlin was hunting over the outer ridges and a Short-eared Owl was hunting marshes to the south.  A Firecrest was along the road edge opposite the Golf Course middle car park.

3rd April. Intermittent rain showers on and off all day resulted in low coverage. There was however evidence of some new migrants in around the East Dunes; 19 Chiffchaff included 7 just around Mill Hill and nearby 12 redwing, 3 Blackcap, 2 Goldcrest. Breaks in the weather encouraged flocks of Siskin and Chaffinch to move south with a Brambling with one flock. Other notable records were 3 Great White Egret on the flooded Freshwater Marsh, seen from Mill Hill, a Hen Harrier and a redhead Goldeneye on Tennyson's Sands.

2nd April. A nice spring day with plenty of sunshine and good coverage of the Reserve today resulting in plenty of good records.. 2 summer plumaged Spoonbill landed on Fenland Lagoon in the morning, one bird sported a white ring NB1N on the left leg, and was thought to be of Dutch origin. Other records around the reserve included a ringtail Hen Harrier over the Old Saltmarsh, a red Kite, a Peregrine, a Great White Egret, 2 Little Ringed Plover (Fenland Lagoon), a Water Pipit, a Stonechat and a Brambling. A Wheatear was a new arrival on the beach out from Mill Hill. 

A Dotted Chestnut was trapped overnight in the moth trap. This is the first record for the reserve with only a handful of Lincolnshire records.

1st April. Another foggy start to the day, with the fog clearing before a bank of drizzle coated the Reserve. Nonetheless, it was mild and calm, plenty of birds were singing and there were new migrants; a few Robins Chiffchaffs, Blackcaps and Thrushes new in. A Tree Sparrow was feeding at the Coastguard Garden and another flew south over the East Dunes. Other birds around included 2 Water Pipit, a Swallow, a Little Ringed Plover, a Red Kite and a Great White Egret.
