- By attacking and killing the weaker bird, the dominant bird is able to assert its dominance and claim the territory or food source as its own. This behavior is also known as kleptoparasitism, which is when one animal exploits another for its own benefit.

What is an example of a flock of birds?
Each individual must follow three basic rules: move in the same direction as your neighbour, stay close to them, and avoid collisions. This relies on sensory systems that detect position and movement accurately, and on rapid responses that co-ordinate directional changes.
Sep 29, 2016 · Birds always seem to avoid one another, even if they’re flying on what looks like a collision course. In a study published Wednesday in PLOS ONE, researchers from the University of Queensland decided to look into how this happens.
Sep 29, 2016 · To answer this question, researchers put parakeets (aka budgerigars) into an air tunnel and had them fly towards each other. They found that birds have evolved a simple way to avoid mid-air collisions: each bird always veers right and changes altitude.
One group of researchers determined that when one starling changes direction or speed, each member of the flock responds almost instantaneously, regardless of the size of the flock—a phenomenon they termed “scale-free correlation.”
Oct 3, 2016 · It's an awkward encounter that seems avoidable, and if people were more like birds, it would be. That's according to new research published last week that describes two simple but crucial adaptations that allow birds to fly in dense flocks without colliding.

Winging at speeds of up to 40 miles per hour, an entire flock of birds can make hairpin turns in an instant. How do they do it? A group of investigators is closer than ever to finding out.
Sep 28, 2016 · How do birds avoid crashing into each other when approaching head-on? They have an in-built preference for veering right. The finding may contribute to the design of better anti-crash...
