Mass songbird migration in the Baltic Sea


This video says about itself:

26 October 2015

A massive and very impressive songbird migration night with thousands of birds crossing the Baltic Sea and resting on a research vessel in October 2015.

The video was made off the coast of north Germany in the 18/19 October 2015 night.

The birds are said to be ‘mostly a mix of bramblings and chaffinches, with some siskins, blackbirds, redwings and skylarks mixed within them.’

This video is the sequel.
