BIRD MIGRATION IS AN ENDLESSLY FASCINATING PHENOMENON THAT TAPS INTO A VARIETY OF OUR BASIC IMPULSES AND DESIRES. <\/p><\/blockquote>\n\n\n\n

\"\"<\/figure>
\n

There\u2019s the sensual, animalistic connection it nurtures and strengthens with the cyclical changing of seasons, and the subtle sub-seasons within them; the odd but very human urge to install order and a sense of control over the relative chaos, by meticulously counting and recording each and every bird \u2013 getting our \u2018ducks in a row\u2019 (often literally); there\u2019s the science-inspired desire to better understand the mechanisms and mysteries of the such natural phenomena that still lie largely outside our understanding (and migration still holds more questions than answers); and at the heart of it, a very pure, childlike wonder that underpins and overarches all of its aspects, and no matter how many hours are spent immersed in it, it seems implausible such a wonder will ever begin to dim. On the contrary \u2013 in truth, that wonder seems to grow progressively brighter as the years go by. <\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

Bird migration is everywhere, making it a universally accessible, constantly changing wonder of nature \u2013 and if you\u2019re lucky enough to live on a coastal flyway at the edge of a continental landmass (well, it was more about planning and sacrifice than luck), then the possibilities for a migration junkie like myself are almost endless. Better still, when you position yourself at the axis of various topographical, geographical and coastal features, there are different \u2018subgenres\u2019 of bird migration that open up to you \u2013 meaning that during the right season, there are different choices, depending on prevailing wind and weather conditions. <\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n
\"\"<\/figure>

Here in the Filey area, on the North Yorkshire coast of England, you can break \u2018active\u2019 migration down into three types: on the ground (where most of the migrants are grounded and feeding \/ resting in situ<\/em>), sea-watching (involving seabirds, wildfowl, waders and whatever else happens to be migrating out over the waves), and visible migration, aka Vismig<\/em><\/strong>.<\/p>\n\n\n\n

Visible migration is, literally, the migration you can observe from where you\u2019re positioned (as opposed to, for instance, the \u2018invisible\u2019 migration that takes place at night, or at higher altitudes). Spring and autumn are both productive, although autumn sees a greater abundance of birds, a wider variety of species, and a longer period of potentially productive passage.<\/p>\n<\/div><\/div>\n\n\n\n

THERE ARE EFFECTIVELY TWO KINDS OF VISMIG MOVEMENTS HERE ON THE NORTH YORKSHIRE COAST: <\/p><\/blockquote>\n\n\n\n

<\/div>\n\n\n\n
\"\"<\/figure>
\n

There are effectively two kinds of vismig movements here on the North Yorkshire coast: inbound (with birds arriving in off the North Sea from mainland Europe, Scandinavia and beyond), and coastal (with birds following the leading line of the coast, generally north in spring and south in summer). Each can see huge, dramatic movements and each is much improved by an appreciation of where best to capitalise on the prevailing movements of the day; for now, we\u2019ll focus on inbound migration (but will take a look at the latter in part two). <\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

When is best? This kind of inbound, oversea vismig is often at its most potently impressive in autumn, and where I\u2019m based \u2013 roughly halfway up the east coast of the UK \u2013 it\u2019s the late autumn influxes of Scandinavian passerines that really take your breath away. <\/p>\n\n\n\n

Birds can arrive in a variety of conditions and at any time of day, but there are certain elements that need to come together for those really big days, and here\u2019s the perfect scenario: <\/p>\n\n\n\n

<\/div>\n\n\n\n
\"\"<\/figure>
\n

It\u2019s mid \/ late October, and countless masses of migrants, waiting to leave Scandinavia, have been temporarily held up by poor weather. Then, suddenly there\u2019s high pressure, clear skies and favourable winds above them, triggering a huge exodus of Redwings, Fieldfares, Blackbirds, various finches, Goldcrests and other songbirds \u2013 which are then drifted by an easterly breeze over the North Sea. As their journey progresses, so they encounter weather \u2013 perhaps low cloud, drizzle, fog, or a combination thereof \u2013 and as navigation becomes more difficult and the risks heighten, making landfall becomes the number one priority.<\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

On clearer nights and days with a similarly beneficial wind (or at least a gentle one), then stopping on the coast isn\u2019t necessary \u2013 why not carry on to more optimal habitats? \u2013 but with challenging weather comes the need to reach dry land above all else. Of course, it\u2019s not always possible to perfectly predict when the big days are going to happen; but with a basic understanding of the weather forecasts and the opportunity to capitalise on them, it\u2019ll happen in a big way a least a handful of times over the season, and to a lesser degree on many other days, too. <\/p>\n\n\n\n

\"\"<\/figure>
\n

And when it happens, there\u2019s nothing quite like it. Stood on the end of Carr Naze, the \u2018topping\u2019 of Filey Brigg \u2013 a promontory that stretches out into the North Sea like a joke shop witches finger just a few minutes from my house \u2013 and soaking up a major arrival is true birding bliss. <\/p>\n<\/div><\/div>\n\n\n\n

Imagine floods of birds arriving at all heights:<\/p>\n\n\n\n

below you as they avoid the waves and follow the cliffs; above you at various levels, from a few metres to wherever visibility ends, ghosting in and out of the cloud bank like distant aircraft; and most spectacularly, at head height \u2013 squadrons appearing out of the grey and bulleting past, sometimes close enough to reveal the exhilarating sound of their wingbeats, just a metre or two away, for a split but unforgettable second.<\/p>\n\n\n\n

On those days, the impulse to count becomes an increasingly doomed and pointless one \u2013 rough estimates are as good as it ever gets \u2013 with birds arriving at all distances and altitudes in unpredictable pulses. But one of the extra-special elements of experiencing such an arrival here at Filey is the opportunity to enjoy the phenomenon at such close quarters \u2013 close enough to feel like you\u2019re in the eye of a unique and welcome storm, and close to enough to look directly into the eyes of many of these death-defying super-travellers as they succeed in their mission to migrate across a rolling, unforgiving North Sea.<\/p>\n\n\n\n
