This 2010 video is called Little Whimbrel [also called little curlew] – Numenius minutus.
This video says about itself:
Little Curlew (Numenius minutus) at Tofta kile, Bohuslän, Sweden. 2019-07-10. Måns Grundsten. Olympus OM-D EM1II, 300mm, 1,4x conv. A far-eastern Siberian long-distance migrant. A true rarity in Europe with less than 10 previous records. Second for Sweden. A good find.
Today, for the first time ever, one was seen in the Netherlands. The photo shows the size difference with the common whimbrel on the left.
