The bright wing patches and long plumes on male birds primarily serve as visual signals in sexual selection. These features attract females by showcasing the male's health, vitality, and genetic fitness, which can indicate their ability to thrive in their environment. Additionally, they may play a role in territory defense and establishing dominance among males. Overall, these traits enhance reproductive success by making males more appealing to potential mates.
Plumes of molten rock originating deep within the mantle are known as mantle plumes. These plumes are believed to be responsible for hotspots and volcanic activity at the Earth's surface.
The plume was made of dyed horse hair. Hair was the preferred material because it lasted longer. The red was to intimidate the enemies with the color red which meant blood. The color red was also a sign that the men were soldiers of the emperor. But remember, the ordinary soldier did not have a plume on his helmet except if he were marching in a triumph. Plumes or distinguishing crests were only for officers. The centurion needed the wide crest so his men could more easily see him in battle
