Part Two – The Birds

As described in Part One, at the end of March last year, with an indefinite lockdown beginning, birding opportunities narrowing, and crucially, Common Scoters audibly beeping outside my bathroom window in the night sky, it was time to give nocturnal migration recording (nocmig) a try.

More than a year on, and it's been a godsend, in a variety of ways: as a distraction in trying times, as a (steep) learning curve for new birding skills and knowledge, as a new method of understanding and appreciating local bird migration, and ultimately, as a little mystery treasure trove to open every morning....

For the first few months it was all about the recorder jammed into the gap in my study window and pointed out into the alley here in Filey town; but by late summer (thanks to YCN!), I'd expanded my set-up, and I was able to run no fewer than three recorders regularly – the second up on the North Cliff here in Filey, and the third over the bay, in a garden in Flamborough Village.

While Part One looked at the how, why, when and where of nocmig, in this second and final part we'll look at the month-by-month results from each location – and it's fair to say, they greatly exceeded all our expectations....

'Graow!' - The first of the Bitterns, over Filey North Cliff


Filey Town

Highlights: hundreds of Common Scoters - the species that kick-started it all!; nine wader species, including four Little Ringed Plovers, the first Greenshank and Grey Plover; two Blackcaps (an unexpected thrill over these urban rooftops!); plenty of wildfowl including GadwallWigeon and Pochard; numerous rails (especially Moorhens and Coots); and lots of returning Scandinavian thrushes, including three figures of Redwings.

Most abundant - Common Scoters (288), Redwing (168), Oystercatcher (38), Common Sandpiper (13) 

Most regular - Redwing (57% of nights), Common Scoter (43%), Oystercatcher (37%)


Filey Town

Highlights: Two QUAILS (10th & 25th) – a joy to pick out among the screaming gulls in the dead of night!; a wider variety of waders, including the first SanderlingsKnot and Turnstones; the first terns - both Sandwich and Arctic; and several long-distance migratory songbirds, including two Lesser WhitethroatsSpotted Flycatcher and a Yellow Wagtail.

Most abundant - Oystercatcher (59), Moorhen (24), Whimbrel (14), Dunlin (12) 

Most regular - Oystercatcher (68%), Moorhen (48%), Little Ringed Plover & Grey Heron (both 23%)

Filey Town

Highlights: plenty of rails (numerous Moorhens, plus Water Rails and Coot); Little Grebes, another Spotted Flycatcher, and (presumably returning) Common Scoter - but, the Herring Gull colony noise was increasingly overwhelming....

Most abundant - Moorhen (30), Oystercatcher (19), Grey Heron (11), Curlew (8)

Most regular - Moorhen (40%), Oystercatcher (37%), Grey Heron (27%), Curlew (13%)



Highlights: recording began from the 10th on the North Cliff here in Filey, which was instantly productive: highlights included a BITTERN (23rd) – a less than annual species here in Filey and a wonderful early reward; twelve wader species (including four Little Ringed Plovers, lots of Curlew and WhimbrelTurnstonesKnotGrey and Golden Plovers); three Water RailsCommon Scoters and much more - a wealth of variety and abundance! The Filey Town recorder was mothballed on 12th due to the Herring Gull colony noise, but still clocked plenty of CurlewsMoorhens and a few other species before then. 

Most abundant (North Cliff) - Curlew (35), Dunlin (21), Oystercatcher (20), Redshank (13)

Most regular (North Cliff) - Curlew & Oystercatcher (both 60%), Dunlin (40%), Redshank (35%)

Very little recording took place in December at North Cliff & Flamborough due weather / practical reasons, with the intention being to resume activities there in early spring....

January and February

Filey North Cliff 

A couple of attempts in January produced Snipe and Mallard before a further eight in February, with Oystercatchers, Snipe, Blackbirds and Song Thrushes from the off; by mid-month, Pink-footed Geese, Wigeon, Lapwings and a mini-movements of Redwings stirred the pot, with further additions of Coot, Moorhen, SkylarksGadwallGolden Plover and Teal in the third week.

So far, so good, but then on the night of the 25th, nocmig gold -  a STONE-CURLEW (only the third ever for Filey), followed by the ghostly howl of a singing Great Northern Diver on 28th!

Filey Town 

Redwing at 0206hrs on Jan 1st even beat the Herring Gulls - a good omen?! Otherwise quiet, with Mallards, Common Gulls, Blackbirds, Song Thrushes, Wigeon and Teal in small numbers, odd Moorhens and Golden Plover, a few skeins of Pink-footed Geese, and the highlight - a flock of Barnacle Geese on 12th. February was a little busier, with new additions including Grey PloverFieldfareLapwing, Coot and other expected early spring migrants, with a nice surprise first for the house on 21st, a Pintail.


Recording commenced from mid-Feb, with Wigeon, Teal, Pink-footed Geese, Moorhens, Coots, Dunlins, Curlews, Lapwings, Blackbirds, Song Thrushes and other early spring movers logged in small numbers, with highlights including a Whooper Swan on 24th and various double-figure Redwing counts, including 47 on 18th.

Filey Town 

Regular Oystercatchers, Black-headed Gulls, Wigeon and Moorhens; shorebird diversity improved as the month went on, with Curlew, Knot, Dunlin, Redshank, Grey and Golden Plovers, plus Coot, Water Rail, and increasing numbers of winter thrushes. Common Scoter flocks featured from 21st, plus Whooper Swans (also 21st), and the highlight – at least two Bean Geese on 13th, a less-than-annual species here in Filey, honking throatily over the chimney pots.

Most abundant - Blackbird (236), Redwing (92), Common Scoter (48)

Most regular - Redwing and Oystercatcher (both 64%), Moorhen (50%)

Filey North Cliff 

Teal, Moorhen, Snipe, Grey Plover, Gadwall, Water Rail, Grey Heron, odd passerines (including Skylark) and a bonus Pintail all featured early on; Common Scoters enlivened recordings from 18th, with Whoopers, Pink-feet and Wigeon, and notable departures of Blackbirds (including 214 on 22nd) following. Lots more scoter flocks followed over several nights, with Golden Plovers, Snipe, small gulls and Redwing movements late month.

Most abundant - Blackbird (276), Redwing (227), Common Scoter (74)

Most regular - Redwing (73%), Moorhen (64%), Blackbird (59%)


Regular Teal, Moorhens, Redwings and Song Thrushes from early on, with Curlew, Oystercatcher, Coot, Skylark, Blackbird and Robin soon added; both Curlew and Redwing clocked significant counts – with e.g. 82 of the former and several flocks of the latter on 17th. Snipe, Grey Heron, Golden Plover, Knot, Dunlin and more were soon added, Wigeon and Curlew movements grew late in the month, but Scoters stole the show with 25 flocks in total. The bird of the month, however, was the Eurasian Bittern which croaked twice over the recorder on 22nd; a less-than-annual rarity on the Head (with two more to follow in April!).

So, an amazing first year, with Stone-curlew, Dotterel,Yellow-browed Warbler, Quails, Bitterns, Short-eared Owl, multiple Tundra Bean and many White-fronted Geese, Little Egrets, Great Northern Diver, Ring Ouzels, Wood Sandpipers, huge movements of other thrushes and geese, a mouth-watering variety (and numbers) of waders, migrating Sylvia warblers and so much more – all in the dead of night via little battery-powered recorders. So much learned, so much still to learn, and so much added to our understanding of migration here on the magical Yorkshire coast.
