News Analysis: Avian Scientists studying the V-Formation Flight Characteristics of Birds have determined that each Bird in formation utilizes the Energy Contribution (EC) of the Bird immediately in front of them. The added wind current of the preceding Bird is used to lessen the Energy Requirements of the subsequent Bird. The Birds learn where their individual flight position is optimal to attain the preceding bird’s ‘EC’. The “Loser” in the ‘EC’ exchange is the Lead Bird many observers might say.
Since some Scientists maintain that the “Head of the Flock” (Older and Wiser) is not necessarily the Lead Bird of a V-Formation, perhaps “Rank Has Its Privileges” in the Avian World also.
Reality.
