SpletFish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency. Splet26. nov. 2024 · The Behavioral Mechanism of Starlings When a flock of starlings confronts threats, individuals near the threat become alert and take action. Because the flock of starlings is too large, it is inevitable that individuals far from the threat will not be aware of danger in the first place. duke metro tower charlotte

C. Rainey and Z. Waloff, working on the desert locust in the 1950s and 1960s. The assumption is that swarms of other locusts behave in the same way, although the other species do not generally form such massive swarms and are much less well studied community britta and jeff
