The New York Times–bestselling author of H is for Hawk explores the human relationship to the natural world in this “dazzling” essay collection (Wall Street Journal). In Vesper Flights, Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing the massive migration of songbirds from the top of the Empire State Building, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk’s poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds’ nests, and the unexpected guidance and comfort we find when watching wildlife.

"Flight is the essence of birdness. I strive to illustrate the beauty and complexity of avian flight." -- Peter Cavanagh 100 Flying Birds: Photographing the Mechanics of Flight offers a vivid and varied glimpse into the world of birds. A white-tailed eagle plummeting through a Japanese sky, a brown pelican striking a silhouette against an Ecuadorian sunset, an Atlantic puffin carrying its fish dinner above the Scottish coast, or a keel-billed toucan gliding through a Costa Rican jungle canopy; readers will marvel at the splendor of birds in flight while learning the techniques to capture these gravity-defying moments from a world-class nature photographer. For each picture, author and photographer Peter Cavanagh shares his most evocative thoughts: the challenges of the shoot, the beauty of the location, and the curiosities of the species. Bird people will enjoy the bird photographs and facts, travelers will gobble up the tales of distant parts, and photographers will absorb the technical details. For instance, readers might be surprised to see that a very slow shutter speed can freeze the motion of hummingbird wings. Peter Cavanagh has collected 100 beautiful photos spanning a wide range of species. The subjects of each of the 11 chapters are: Eagles Hummingbirds Gulls and Terns Small Waterbirds Large Waterbirds Ducks, Geese and Swans Raptors Condors and Corvids Cranes Songbirds Favorites

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.

How Birds Fly is a captivating, non-technical introduction to bird flight. The book reveals the mysteries of flapping flight with sequences of high-speed photographs that lead step-by-step through fine points of take-off, level flight and slow flight.

Maggie has just learned to fly when she crashes into the side of a building. She falls to the ground, alone and injured. Who will help her? As told with real photographs, this true story explains how wildlife hospitals rescue and treat injured animals. Their goal is to release the animals back into the wild. Sometimes, this isn't possible--but there can still be a happy ending. Maggie's story, written by Christie Gove-Berg, is just such a success!
