Book Description
How birds have evolved and adapted to survive winter Birds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds’ lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success. Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season’s distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider. Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.

Book Description
Every spring, billions of birds sweep north. This vast parade often goes unnoticed, except in a few places where these small travelers concentrate in large numbers. One such place is along Lake Erie in northwestern Ohio. Millions of winged migrants pass through the region. Now climate change threatens to disrupt patterns of migration and the delicate balance between birds, seasons, and habitats

Book Description
What is it like to be a swift, flying at over one hundred kilometres an hour? Or a kiwi, plodding flightlessly among the humid undergrowth in the pitch dark of a New Zealand night? And what is going on inside the head of a nightingale as it sings, and how does its brain improvise?Bird Sense addresses questions like these and many more, by describing the senses of birds that enable them to interpret their environment and to interact with each other. Our affinity for birds is often said to be the result of shared senses - vision and hearing - but how exactly do their senses compare with our own? And what about a birds' sense of taste, or smell, or touch or the ability to detect the earth's magnetic field? Or the extraordinary ability of desert birds to detect rain hundreds of kilometres away - how do they do it?Bird Sense is based on a conviction that we have consistently underestimated what goes on in a bird's head. Our understanding of bird behaviour is simultaneously informed and constrained by the way we watch and study them. By drawing attention to the way these frameworks both facilitate and inhibit discovery, it identifies ways we can escape from them to seek new horizons in bird behaviour.There has never been a popular book about the senses of birds. No one has previously looked at how birds interpret the world or the way the behaviour of birds is shaped by their senses. A lifetime spent studying birds has provided Tim Birkhead with a wealth of observation and an understanding of birds and their behaviour that is firmly grounded in science.

Book Description
Most birds cannot cover the distance between their breeding and winter quarters in one hop. They have to make multiple flights alternated with stopovers. Which factors govern the birds’ decisions to stop, to stop for how long, when to resume flight? What is better – to accumulate much fuel and to make long flights for many hundreds of kilometres, or to travel in small steps? Is it necessary to find habitats similar to the breeding ones or other habitats would do? Are long migratory flights indeed so costly energetically as usually assumed? This monograph summarizes our current knowledge on the ecology of songbird migrants during migratory stopovers and on their behaviour.​

Book Description
From the bestselling author of The Robin, The Wren and The Twelve Birds of Christmas. With around 700,000 breeding pairs, the swallow is one of the most familiar birds in Britain. Though we consider the swallow to be 'our' bird, we also share this beloved creature with millions of others across the globe. Whilst we see it on a daily basis for half the year, the swallow then flies south to Africa, living on only in our memory in the long, dark winter. In The Swallow Stephen Moss documents a year of observing the swallow close to home and in the field to shed light on the secret life of this extraordinary bird. We trace the swallow's life cycle and journey, including the epic 12,000-mile round trip it takes every year, to enable it to enjoy a life of almost eternal sunshine, and the key part the swallow plays in our traditional and popular culture. With beautiful illustrations throughout, this captivating year-in-the-life biography reveals the hidden secrets of this charismatic and beautiful bird. PRAISE FOR STEPHEN MOSS: 'A superb naturalist and writer' Chris Packham 'Inspired, friendly and blessed with apparently limitless knowledge' Peter Marren 'Moss has carved out an enviable niche as a chronicler of the natural world' Daily Mail
