Quantifying the dynamic wing morphing of hovering hummingbird
Animal wings are lightweight and flexible; hence, during flapping flight their shapes change. It has been known that such dynamic wing morphing reduces aerodynamic cost in insects, but the consequences in vertebrate flyers, particularly birds, are not well understood. We have developed a method to reconstruct a three-dimensional wing model of a bird from the wing outline and the feather shafts ...
متن کاملHovering hummingbird wing aerodynamics during the annual cycle. I. Complete wing
The diverse hummingbird family (Trochilidae) has unique adaptations for nectarivory, among which is the ability to sustain hover-feeding. As hummingbirds mainly feed while hovering, it is crucial to maintain this ability throughout the annual cycle-especially during flight-feather moult, in which wing area is reduced. To quantify the aerodynamic characteristics and flow mechanisms of a hummingb...
متن کاملHovering hummingbird wing aerodynamics during the annual cycle. II. Implications of wing feather moult
Birds usually moult their feathers in a particular sequence which may incur aerodynamic, physiological and behavioural implications. Among birds, hummingbirds are unique species in their sustained hovering flight. Because hummingbirds frequently hover-feed, they must maintain sufficiently high flight capacities even when moulting their flight feathers. A hummingbird wing consists of 10 primary ...
متن کاملNew Protocol for Measuring Lepidoptera Wing Damage
Lepidoptera may acquire damage to their wings throughout their lifespan. The ability to quantify the accumulated damage is relevant when studying the impact of wing damage on territorial behavior, mating systems, predation, or assessing relative age of the insect, but unfortunately, methods for accurate insect wing damage quantification are scarce. The purpose of this paper is to introduce a ne...
متن کاملComprehension of Stories with No-Obstacle and Obstacle Endings
GOLDMAN, SUSAN R., and VARNHAGEN, CONNIE K. Comprehension of Stories with No-Obstacle and Obstacle Endings. CHILD DEVELOPMENT, 1983, 54, 980-992. Comprehension of stories with and without obstacles to goal attainment was examined. 16 secondand fifth-grade students and 16 adults listened to and read single-episode stories in which (1) the protagonist met the episode goal (no-obstacle ending) and...
