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.
