It looks more like they are individual birds, looking at the shape and proportional size. In certain airports in the UK we have vehicles which drive around the airport and make sounds which sound like a predator bird , if there is a group of birds spotted in the way- it scares them off.
Most of Europe has a high population of birds due to the climate and seasons, so I assume there are similar operations, hopefully not as daft as that.
