空气动力学理论预测，随着内源性能量储备的逐渐消耗，候鸟会降低飞行速度。这一预测在1987年和1998年两次通过巴拿马中部迁徙的乌拉尼亚·富尔根斯（沃克）飞蛾中得到了验证。直接空速测量和氯仿甲醇提取腹部脂质被用来确定，与理论预测相反，个体之间的飞行速度与体重和腹部脂质无关。
Aerodynamic theory predicts that migrant fliers should reduce their speed of flight as endogenous energy reserves are gradually consumed. This prediction was tested for Urania fulgens (Walker) moths migrating through central Panama in 1987 and again in 1998. Direct airspeed measurements together with chloroform: methanol extractions of abdominal lipids were used to determine that, contrary to theoretical predictions, the speed of flight among individuals was independent of both body mass and abdominal lipid mass.
