All 155 people on board survived and were rescued by nearby boats. Sullenberger said later: "It was very quiet as we worked, my copilot Jeff Skiles and

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
