On winter mornings, I would see the 1 sight of bird flocks dancing across the landscape, a distant cacophony (刺耳的嘈杂声) 2 above the fields. They were jackdaws (寒鸦), the smallest member of the crow family. Research led by Masters student Alex Dibnah asked: Why are jackdaws so loud when they 3 ? Then he began to work with a team. The team’s 4 was that the morning calls might be a jackdaw version of “ 5 ”. Each individual’s call might 6 as an “I’m in!” helping them coordinate (协调) their 7 . To test this, the researchers artificially 8 call levels during the jackdaws’ morning cacophony using speakers at their sleeping sites. When extra calls were played, the jackdaws 9 earlier, showing they use calls as a check-in system. Individual jackdaws 10 from leaving with the flock because they get more social information like where to find food, they can maximize their time spent finding food, and they’re less 11 being attacked. This sort of decision-making isn’t 12 to jackdaws — it’s been reported in other species as well. So, the cacophony of jackdaws in the morning is a clever solution to 13 a large group.
