类似的飞行控制原理适用于昆虫和脊椎动物。这些原则表明，稳健的解决方案已经发展到可以应对复杂的行为挑战。继对昆虫飞行的视觉和颈部反馈控制的研究之后，我们研究了头部稳定在控制鸽子转向飞行中提供反馈线索的作用。基于先前的观察，鸽子的眼睛在飞行过程中在头部保持相对固定的方向，我们测试了在90°空中转弯时头部和身体运动产生的潜在感觉控制输入。我们观察到，角头部稳定的周期与快速头部重新定位运动（头跳）交替进行，并证实了头部运动的控制与旋转拍击飞行过程中作用在鸟类连续旋转身体上的气动和惯性力是分离的。从头部扫视推断的视觉线索与飞行轨迹的变化相关；而颈部弯曲的幅度则预示着身体位置的角度变化。因此，除了提供控制身体和翅膀运动的机制外，控制头部运动以稳定鸽子的凝视可能有助于提取重要的运动线索。鸟类和昆虫的感官飞行控制之间的强烈相似性也可能激发人类工程自主飞行器的鲁棒控制器的新设计。
Similar flight control principles operate across insect and vertebrate fliers. These principles indicate that robust solutions have evolved to meet complex behavioral challenges. Following from studies of visual and cervical feedback control of flight in insects, we investigate the role of head stabilization in providing feedback cues for controlling turning flight in pigeons. Based on previous observations that the eyes of pigeons remain at relatively fixed orientations within the head during flight, we test potential sensory control inputs derived from head and body movements during 90° aerial turns. We observe that periods of angular head stabilization alternate with rapid head repositioning movements (head saccades), and confirm that control of head motion is decoupled from aerodynamic and inertial forces acting on the bird's continuously rotating body during turning flapping flight. Visual cues inferred from head saccades correlate with changes in flight trajectory; whereas the magnitude of neck bending predicts angular changes in body position. The control of head motion to stabilize a pigeon's gaze may therefore facilitate extraction of important motion cues, in addition to offering mechanisms for controlling body and wing movements. Strong similarities between the sensory flight control of birds and insects may also inspire novel designs of robust controllers for human-engineered autonomous aerial vehicles.
