Witnessing the great Migration @ Falsterbo - Sweden


Imagine yourself sitting on a sea coast with a cup of hot coffee, looking up the sky. Every minute you see waves after waves of birds, in huge numbers, crossing over your head. By huge, we mean not tens not hundreds, not even thousands - it is tens of thousands on a single day! Would it not be a delight for a bird watcher to do this kind of birding? Well, it is not a fantasy; it’s about a place called Falsterbo where this happens almost every day in autumn. Birds leaving Scandinavia before winter, cross this place in numbers as big as a few millions. To be in Scandinavia and not to visit Falsterbo, especially in autumn would be a great sin for a birder! We knew this is the place to go in autumn.

About Falsterbo: 
Falsterbo is an anvil shaped peninsula on the South westernmost part on Sweden. It is said to have formed about 10000 years ago during the end of the last Ice age when the glaciers retreated and left behind a series of moraine hummocks. Over thousands of years, shifting sands emerged in between and eventually the small anvil-shaped peninsula formed as we see it today.

It is estimated that about 500 million birds leave the Nordic countries every autumn, migrating to the south, some diurnal and some nocturnal and some both. Out of these, in Falsaterbo alone, 1-3 million diurnal migrant birds have been counted. On a clear day it would be a delight to watch flocks after flocks of various species of birds, flying in various sized flocks, or some even loners, and at various altitudes. Autumn migration here starts in July itself, when it is still Summer and goes on till almost November. And throughout the season, there are different species migrating, some early and some late. With Scandinavian weather being highly varied and hardly predictable, the migration on a particular day largely depends on the weather conditions suitable to that bird.

Why Falsterbo?
For migratory birds, it is a matter of compulsion to migrate to a better place mainly for availability of food supply. Since they will be faced with many threats on their way like lack of food, resting place, becoming preys, large expanses of sea, bad climatic conditions and many more, they often choose a safe path as far as possible.

Land based birds on autumn migration fly as far as possible along the coast, heading south west and they reach the Swedish west coast and since they try to avoid huge expanses of sea, they eventually get channeled to Falsterbo peninsula. From here, the birds have no choice but to venture out over the sea to reach the next land mass.

More facts about bird migration:

 - We learnt that passerines mostly migrate by the night for various reasons which includes being safe from raptors. And they typically take shelter in Falsterbo lighthouse garden at day break before continuing on their journey forward. 

Blue Tit - a partial migrant
 - Raptors usually migrate in the middle of the day, when the sun is high up in the horizon, using thermals to soar up in the sky. It is said that in right thermal conditions, buzzards can soar and cover a distance of up to 12 km without a single wing beat; and for eagles it is up to 20km! Birders at Falsterbo call the time between 12 to 1pm as ‘Eagle hour’ because if at all raptors are to be spotted, they will be during that hour.

 - Since we chose early-autumn (early September), we got a mix of passerines, water birds, a few waders and raptors.

 - There was a continuous flight of Honey Buzzards and Marsh Harriers, not in huge flocks, but in singles, pairs and groups of threes and fours.

- It was raining Sparrow Hawks! Everywhere we saw, there surely was a Sparrow Hawk or two; some migrating, some residents. It was as if they were following us everywhere we went, right from the moment we landed in Falsterbo!

 - Some of the raptors like Merlin, Hobby and Osprey were lifers for us!

 - Geese were arriving and departing in flocks after flocks, making loud calls in their typical V-formation

 - We didn’t spot any Owls in the woods, though we longed to see them. We were told that they were in huge numbers the previous year, and as a result rodent population had reduced drastically. However the reduced rodent population meant that there was no food supply for Owls now and they too have almost vanished from the place.

 - Weather in Scandinavia predictably highly unpredictable! The days we chose were not the best of the days in terms of number of birds, it was a great experience nevertheless.

A few more Canada Geese
 - The ornithologists at ‘Falsterbo Fagel Station’ are doing a wonderful job, studying the bird migration here and ringing the birds. Two people stand at the prime point Nabben, from dawn to dusk, despite the harsh weather, meticulously noting down the bird species and counting each species. Note that on days with great weather, this count can be a few hundred thousand too!

 - And seasoned birders, who have been studying the migration from decades, stand in front of the lighthouse, another good point for witnessing migration, from morning till late afternoon, just guiding amateur birders like us, helping with Ids and sharing fascinating bird facts. That was something greatly appreciated.

 - Coming to bird ringing, trapping, ringing and releasing birds requires handling them with utmost care and it was amazing to see the dedication with which it was done. The birds were handled as soon as they were trapped, and the ringing done right at the same spot, and released, all in a matter of a few minutes, making sure the bird is not held for longer than necessary.

 - We could rent bicycles there and cover most of the birding areas in Falsterbo and Skanor. A sign we spotted while riding… feels good to see that little creatures are regarded too :). There were other signs of Avocets crossing roads, as well!

Finally a Metal Bird!
We must say few words about the people at Falsterbo who have been studying bird migration over many years now. They are doing really a wonderful job out there which was an eye opener for us. They have been maintaining everyday reports of all birds sighted and their respective counts from ages. It can be found here.

Some serious Birders at Falsterbo

‘Wings Over Falsterbo’ is a book which is about bird migration at Falsterbo but also contains many interesting facts about bird migration in general! This book is co authored by many reputed ornithologists and greatly benefited us!

We are grateful to people at Falsterbo Fagelstation who made this possible for us!!! A BIG THANK YOU FOLKS!!
