A surrogate forelimb: evolution, function and development of the avian cervical spine

RD Marek - Journal of Morphology, 2023 - Wiley Online Library
The neck is a critical portion of the avian spine, one that works in tandem with the beak to act
as a surrogate forelimb and allows birds to manipulate their surroundings despite the lack of …

Optic flow based spatial vision in insects

M Egelhaaf - Journal of Comparative Physiology A, 2023 - Springer
The optic flow, ie, the displacement of retinal images of objects in the environment induced
by self-motion, is an important source of spatial information, especially for fast-flying insects …

A novel dynamic stabilization and vibration isolation structure inspired by the role of avian neck

X Sun, F Wang, J Xu - International Journal of Mechanical Sciences, 2021 - Elsevier
A novel multi-layer structure with functions for dynamic stabilization and vibration isolation,

Turbulence explains the accelerations of an eagle in natural flight

KM Laurent, B Fogg, T Ginsburg… - Proceedings of the …, 2021 - National Acad Sciences
Turbulent winds and gusts fluctuate on a wide range of timescales from milliseconds to
minutes and longer, a range that overlaps the timescales of avian flight behavior, yet the …

Flight mechanics and control of escape manoeuvres in hummingbirds. I. Flight kinematics

B Cheng, BW Tobalske, DR Powers… - Journal of …, 2016 - journals.biologists.com
Hummingbirds are nature's masters of aerobatic manoeuvres. Previous research shows that

Optimization of avian perching manoeuvres

M KleinHeerenbrink, LA France, CH Brighton… - Nature, 2022 - nature.com
Perching at speed is among the most demanding flight behaviours that birds perform, and is
beyond the capability of most autonomous vehicles. Smaller birds may touch down by …

Visual guidance of forward flight in hummingbirds reveals control based on image features instead of pattern velocity

R Dakin, TK Fellows… - Proceedings of the …, 2016 - National Acad Sciences
Information about self-motion and obstacles in the environment is encoded by optic flow, the
movement of images on the eye. Decades of research have revealed that flying insects …

The role of passive avian head stabilization in flapping flight

AE Pete, D Kress, MA Dimitrov… - Journal of The Royal …, 2015 - royalsocietypublishing.org
Birds improve vision by stabilizing head position relative to their surroundings, while their
body is forced up and down during flapping flight. Stabilization is facilitated by compensatory …
