Tens of thousands of buzzards filled Dutch skies in October through ‘correction draft’ | NOW

Tens of thousands of buzzards visited the Netherlands between 14 and 17 October during their migration to the south. According to the Bird Protection, the birds have broken several records.

Bird watchers sometimes spot groups of thirty or forty buzzards every autumn. But groups of a hundred birds or more are exceptional, the organization writes on the website on Tuesday Nature Today.

The daily record for the number of buzzards sighted so far stood on October 16, 2010, when Dutch amateur ornithologists peated 1,075 specimens at one watchpoint.

In the second week of October this record was broken twice, on October 14 and 15. The record holder is now the Twente Losser, where 1,793 copies were counted in one day.

A swarm of over twelve thousand buzzards crossed the Wadden

A total of nine Dutch sites broke their own daily record that week. It is possible that some posts have observed the same specimens, the Vogelbescherming acknowledges. Yet the club of experts speaks of “un-Dutch situations”.

The largest swarm was observed on 17 October, when more than 1,200 buzzards flew from Den Helder via the islands of Texel, Terschelling and Ameland to shore and then flew further south.

The birds did a ‘correction pull’, they had wandered

Bird Protection speaks of a “correction pull”. Buzzards migrate from north to south in the autumn, because there is no food in the winter in Scandinavia, for example. The birds depend on the weather conditions; for example, they use warm air to glide and tailwind to gain momentum.

In general, buzzards try to fly straight south as much as possible. But due to a strong north-eastern current, the birds drifted en masse towards the Netherlands. Only at the height of the North Sea do the animals realize that they are ‘wrong’ and correct their flight to the original ‘course’ towards the south of Germany.

It is a great month for Dutch bird watchers anyway. Last weekend, a rare black-headed warbler was spotted for the first time on Texel, who flew from North America to Europe in one go. This last weekend led to a tsunami of amateur ornithologists to the Wadden Island.
