Sort sol takes place in the hours just after sunset. The birds gather in large flocks and form huge formations in the sky just before they decide for a location to roost for the night. The movements of the formations have been likened to kind of a dance or ballet and the birds are so numerous that they seem to obliterate the sunset, hence the term "sort sol" (Danish for "black sun"). Sort sol in the marsh near Tønder can occasionally comprise a formation with up to one million birds. Usually flocks break up when the number of individuals exceed about half a million birds due to excessive internal disturbances in the flock.
If a predator bird enters the flock, the starlings initiate a veritable bombardment with droppings and vomit that soil the feathers of the predator. In rare cases the sticky deposits may render the predator unable to stay airborne. Over 20 years, there have been two confirmed cases of young northern goshawks that drowned because the incident took place over water."
