Without engine power and judging themselves unable to reach nearby airports (Teterboro Airport being the closest), Sully ditches the aircraft on the Hudson River. The crew and passengers evacuate without casualty. The press and public hail Sullenburger a hero, but the incident leaves him haunted, and
Flock (birds) it is specifically the two different behaviours of the species that compose a mixed flock. Within a mixed flock there can be two different behavioural characteristics: sally and gleaner. Sallies are individuals that act as guards of the flock and consume prey in the air during flight. On the other hand, gleaners are those that consume prey living within vegetation. Studies have shown that as resources in the aerial environment increase, the flock will possess more sallies than gleaners. This has been shown to occur during forest fires in which insects have been flushed from vegetation, however this can also
