29th March to 10th April – Modest arrivals of spring migrants including several more 'firsts' for the year

Highlights from the LFS logbook for the last two weeks (29 Mar to 10 Apr) are listed below, with records of more notable species highlighted in blue. Many thanks to Dean Jones for providing a digital copy of logbook entries enabling this summary to be compiled.

Unsettled weather, with showers and longer spells of rain at the end of March gave way to predominantly dry and often sunny conditions during the first ten days of April, with high pressure ruling the roost. Clear skies brought frequently sunny days to the island, but chilly nights (alongside a waxing moon, full on 11th), whilst daytime temperatures were pegged back by winds mainly from the north and west, though there was a short-lived incursion of warmer, continental air during the weekend of 8/9 April. There was another Osprey on 2nd, an influx of Swallows on 6th & 7th, a modest arrival of 20 Willow Warblers on 7th, and first records for the year of single Sandwich Tern (1st), Common Redstart (9th) and Grasshopper Warbler (8th). In general though, visible migration was sluggish, as is often the case in fine weather, when birds tend to overfly Lundy having little need to make landfall on a remote island. Having said that, it is still early in the season and many summer migrants are yet to reach Britain in significant numbers. Lingering winter birds included Great Northern Diver, Red-necked Grebe and the odd Redwing.

Great Northern Diver: One on 1st.
Red-necked Grebe: The overwintering bird was still in the Landing Bay on 30th (Dean Jones), but then looked like it might have commenced its spring migration as there were no reports during the first week of Apr. Confounding any such assumptions, the bird was again in the Landing Bay, off the Sugar Loaf, on 9 Apr (Dean Jones & Zoë Barton).
Fulmar: Max 153 on 31st.
Manx Shearwater: Max 300, flying west off North Light on 1st (Martin Thorne).
Gannet: Max 10 on 1st.
Cormorant: Six flying north on 6th.
Sparrowhawk: A male on 31st.
Osprey: One moving rapidly north-east off the Terrace on 2nd; the second of the spring so far (Solomon Gilbert).
Snipe: Three on 31st and one on 7th.
Kittiwake: Max 137 on 31st.
Black-headed Gull: An adult in the Landing Bay on 28th (Kevin Welsh) and four reported on 3rd.
Sandwich Tern: One on 1st was the first of the year.
Puffin: Max 97 on 29th (of which 77 prospecting on land) and 60+ in Jenny's Cove on 1st.
Guillemot: Max 1,212 on 29th.
Woodpigeon: Max five on 7th.
Sand Martin: Records on six dates; max 16 on 1st and 20 on 7th.
Swallow: Records on seven dates; max 78 on 6th and 100 on 7th.
House Martin: Three on 31st was the only record.
Pied Wagtail: Max six on 8th.
White Wagtail: Two on 31st.
Robin: A bird was carrying nesting material in Millcombe on 7th.
Black Redstart: Records on six dates, with a female-type on 31st, 2m + 1f on 1st, 1f 6th-8th and 1m on 9th.

Common Redstart: A single male on gorse near the Rocket Pole on 9th was the first of the spring (Dean Jones & Zoë Barton).
Wheatear: Max 25 on 1st and 21 on 9th; several more colour-rings were read.
Redwing: Singles on 31st and 7th (latter in Millcombe).
Song Thrush: Three on 31st but no Apr records so far.
Blackcap: Ones and twos on six dates, plus the max of five on 3rd.
Grasshopper Warbler: One reeling from cover in St John's Valley on 8th was the first of the spring.
Willow Warbler: Records for six dates, with a max of 20 on 7th.
Chiffchaff: Records for five dates, with a max of seven on 1st & 7th.
Goldcrest: Records on three dates, with a max of three on 7th.
Linnet: Max 11 on 6th.
Goldfinch: Max 10 on 31st and 13 on 6th.

Invertebrate records have included a Black Oil Beetle (3rd), 11 Dor Beetles and 3 Minotaur Beetles (5th); the first Peacock (6th) and Green-veined White (8th) butterflies of the year; and two Diamond-back Moths (9th).

28th March – A change in the weather and a lull in migration

After several days of clear blue skies and a stiff easterly, Tuesday saw the wind veering south, then south-west, bringing cloud and showery rain during the afternoon. Although there was a good scattering of Phylloscopus warblers along the East Side combes and on the Terrace (totalling an estimated 30 Chiffchaffs and 15 Willow Warblers), the range and volume of migrants was generally reduced. Among the more notable sightings were about a dozen Pied Wagtails and 4 White Wagtails, 2 Blackcaps, flocks of 6 + 8 Cormorants (all except one were breeding-plumaged adults) flying north, and a handful of Sand Martins and Swallows. Several Song Thrushes may have been lingering from Monday's influx, whilst the female Bullfinch certainly was, having apparently not moved from her favourite blackthorn bush for 24 hours!

Two of the Robins seen during the day had the greyish tones and pallid orange breasts associated with continental birds (see the Skokholm Observatory blog for 28th March). The 1st-summer Great Northern Diver and the Red-necked Grebe (now showing quite extensive signs of breeding plumage) continued their sojourns in the Landing Bay, the grebe taking to the air briefy as MS Oldenburg, on her first scheduled sailing of the year, hove into view.

Birds seen during the late-afternoon crossing back to Ilfracombe included a single Manx Shearwater, 5 Common Gulls, and a few Fulmars, Gannets, Kittiwakes and auks. A Sandwich Tern was flying around Ilfracombe harbour to greet disembarking passengers, just as the rain began to fall in earnest...

27th March – Osprey through and first Blackcaps of the year

Tim Davis, Tim Jones and Tony Taylor report excellent views of an Osprey arriving low below Castle Hill before climbing as it moved north along the East Side, mobbed by gulls and corvids (record shot below).

An influx of thrushes included 2 male Ring Ouzels on the Terrace, up to 15 Song Thrushes and a noticeable increase in Blackbirds. Auk numbers totalled 99 Puffins in Jenny's Cove, with 900 Guillemots on the ledges and a further 200 on the water and 400 Razorbills. Puffins were later seen on land for the first time this season, exploring nesting burrows. There was a Golden Plover calling in flight over the Airfield and the Jackdaw count increased to four, all of which were seen apparently leaving the island to the NNE over the Terrace during the morning. A female Bullfinch feeding on blackthorn buds at the head of St Helen's Combe was unusual for the island, though most recent records are for March and April. Hirundine passage comprised 75 Sand Martins and 4 Swallows. There was a count of 20 Willow Warblers and the first Blackcaps of the year were recorded; a female and two males – the female feeding on rocky slopes at North Light! Two Siskins were present on feeders in the Village, there were several White Wagtails alongside migrant Pieds and the Red-necked Grebe was still in the Landing Bay. Finally an extremely dark-mantled adult Lesser Black-backed Gull – as dark as the adult Great Black-back standing next to it and therefore presumed to be of the continental breeding race L. f. intermedius – was at Pondsbury in the afternoon.

Seven Manx Shearwaters were caught at the Old Light study colony between 9.30pm & 11.00pm, comprising four new birds and three retraps.

The lighter winds and warm sunshine made it a good day for invertebrates:

26th March – Grey Heron and three Jackdaws

Tim Jones and Tim Davis report 58 Puffins in Jenny's Cove. In the strong easterly wind, 110 Sand Martins and 25 Swallows were counted moving north in the lee of the West Side. A Grey Heron flew across the South End and there were 3 Jackdaws in Lighthouse Field. The Meadow Pipit count totalled 400 and 20 Linnets and a Siskin were observed. The Red-necked Grebe and Great Northern Diver were still present.

25th March – Strong Meadow Pipit passage

Tim Davis and Tim Jones report 41 Puffins in Jenny's Cove and a strong passage of Meadow Pipits amounting to 500 birds, including 300 moving north in the lee of the West Side in the early morning. Other sightings included 22 Sand Martin, 2 Swallow, a Lapwing flying in off the sea at Jenny's Cove, 2 Jackdaws over the East Side and a female Siskin in the camping field. The Great Northern Diver and Red-necked Grebe were still present in the Landing Bay.

A brief visit to the shearwater study colony near Old Light, on a beautiful, moonless but starlit night, revealed the presence of calling Manx Shearwaters and birds of breeding age already visiting their nesting burrows. Two individuals ringed in previous years were retrapped. During the afternoon, Tony Taylor, Dean Jones and the two Tims had completed a pre-season check of the shearwater nestboxes installed in 2016, some of which already showed signs of visitation this year.

24th March – Wheatear seen on Guernsey back on territory

Tim Jones and Tim Davis report 250 Razorbills off the South End, but a big clear-out of Chiffchaffs and Meadow Pipits with only 12 and 70 respectively logged. A total of 240 Kittiwakes were counted at the two remaining West Side colonies. Of note were 2 Black Redstarts, a "singing" Water Rail, 6 Teal, 4 Snipe and a Song Thrush. The day's highlight was confirmation that the colour-ringed male Wheatear seen on Guernsey on 13 March (see blog post dated 14 March) was back on its territory near the Earthquake, in hot pursuit of a female and fending off another male – record shots below.

Now on its Lundy breeding territory, this bird was seen on Guernsey on 13 Mar

23rd March – Chiffchaff fall and returning female Wheatears

Tim Davis and Tim Jones report 60+ Chiffchaffs hopping around on the fields and walls. Meadow Pipit numbers totalled 300, with 5 Black Redstarts, 2 Redwings, a Song Thrush, a Sand Martin and 2 Swallows seen. Three more Wheatear colour rings were read, including two females – the first known returning females for the year. Rafts totalling 500 Razorbills were counted off the South End in the early morning. The Red-necked Grebe was still present.
