Birds adjust flight speed according to their circumstances, and as such avian flight is a behavioural attribute rich with ecological implications. Flight mechanical theory enables the power expenditure of flight to be reliably estimated and was incorporated into foraging theory to predict the flight speed of foragers in a patchy habitat. The basic prediction is that at the net energy intake rate maximizing flight speed, the marginal cost of a further increase in flight speed matches the net rate of intake. This equality could theoretically be used in reverse, providing a relatively simple method to estimate the net energy intake rate. This could be useful for habitat quality assessments and conservation planning because intake rate estimates are otherwise often time-consuming, labor-intensive, and difficult. In this thesis I measured the flight speed of foragers in two natural foraging scenarios, and in an experiment in which I manipulated the attainable rate of energy intake. I demonstrate step-by-step how to predict net energy intake rate from flight speed including corrections for wind, flight distance (i.e., inter-patch distance) and flock size, all of which affect the power requirements of flight. The data support the theoretical predictions of the effects of wind and flight distance, as well as the effect of flock size (though interpretation of the latter remains uncertain because another published model makes reverse predictions). The data give limited support for the prediction that foragers adjust flight speed in relation to habitat foraging quality. Dunlin (Calidris alpina) flight speed slowed as predicted in the course of the winter on one mudflat, but not on another. As predicted, migrant western sandpipers (Calidris mauri) fly faster on small than on large mudflats, but the differences are slight and flight speed appears slow relative to predictions. Steller's jays (Cyanocitta cristatus) did not fly faster between patches in response to a manipulation of patch quality. Overall, about half of the flight speeds I measured were at maximum range speed or slower. I suggest that this might be explained if foragers were maximizing not the intake rate but the foraging gain ratio.

This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program.The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats. * An up to date work by the world's leading expert on bird flight* Examines the biology and biomechanics of bird flight with added reference to the flight of bats and pterosaurs.* Uses proven aeronautical principles to help solve biological issues in understanding and predicting the flight capabilities of birds and other vertebrates.* Provides insights into the evolution of flight and the likely capabilities of extinct birds and reptiles.* Gives a detailed explanation of the science behind, and use of, the author's predictive bird flight simulation program - Flight - which is available on a companion website.* Presents often difficult concepts in easily understood language.

Avian Flight covers all the main aspects of aerial locomotion by birds including sections on the history of thinking about bird flight, aerodynamics, functional morphology, evolution, kinematics, physiology, energetics and the cost of flight. The subject is complex and still not yet fully understood, and the author argues a convincing case for rethinking or even abandoning some of the old, well-established concepts.
