The Flight of Birds
نویسنده
چکیده
In a previous paper (Brown, 1948), the movements of the wing of a pigeon in slow flight were analysed. With the help of a new photographic technique further work on the flight movements at different forward velocities has been carried out. In this paper the analysis is extended with additional information obtained from normal cine-photography. Certain improvements and simplifications in the flash cinematographic methods are also described.

A Flight Mechanics-Centric Review of Bird-Scale Flapping Flight
This paper reviews the flight mechanics and control of birds and bird-size aircraft. It is intended to fill a niche in the current survey literature which focuses primarily on the aerodynamics, flight dynamics and control of insect scale flight. We review the flight mechanics from first principles and summarize some recent results on the stability and control of birds and bird-scale aircraft. B...
متن کاملFlight performance of western sandpipers, Calidris mauri, remains uncompromised when mounting an acute phase immune response.
Migratory birds have been implicated in the spread of some zoonotic diseases, but how well infected individuals can fly remains poorly understood. We used western sandpipers, Calidris mauri, to experimentally test whether flight is affected when long-distance migrants are mounting an immune response and whether migrants maintain immune defences during a flight in a wind tunnel. We measured five...
متن کاملAvian Wing Proportions and Flight Styles: First Step towards Predicting the Flight Modes of Mesozoic Birds
We investigated the relationship between wing element proportions and flight mode in a dataset of living avian species to provide a framework for making basic estimates of the range of flight styles evolved by Mesozoic birds. Our results show that feather length (f(prim)) and total arm length (ta) (sum of the humerus, ulna and manus length) ratios differ significantly between four flight style ...
متن کاملWind estimation based on thermal soaring of birds
The flight performance of birds is strongly affected by the dynamic state of the atmosphere at the birds' locations. Studies of flight and its impact on the movement ecology of birds must consider the wind to help us understand aerodynamics and bird flight strategies. Here, we introduce a systematic approach to evaluate wind speed and direction from the high-frequency GPS recordings from bird-b...
متن کاملInfluence of Phytase on Tibia Bone Characteristics of Broiler Quail Fed on Corn-Soybean Meal Diets
BACKGROUND: Exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. OBJECTIVES: In the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. METHODS: In a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. All birds received one of four experimen...
متن کاملThe energy cost of loaded flight is substantially lower than expected due to alterations in flight kinematics.
The effect of experimentally increased wing loading on the energy cost of flight was examined in cockatiels Nyphicus hollandicus. Five individuals were flown for periods of approximately 2 min, while carrying additional payload mass amounting to between 5 and 20% of unloaded body mass. The energy cost of flight was measured using the 13C-labelled bicarbonate technique, which was also calibrated...
