Day started at Ružinov cemetery. We were searching for wintering Long-eared Owls, but we were unsuccessful. Coal Tit, Marsh Tit and couple of Treecreepers took up our mood. We were reported that there is a large flock of Waxwings on our way to city center. We estimated 600-800 birds in the flock. I made this video:
I took few frames and tried to count the birds in it.
Result is that our estimated number of individuals in the flock was absolutely wrong. According to the definition of the video I counted 1690 birds and overall revised count is somewhere around 1600-1800 birds.
