A stunningly illustrated look at the mating and parenting lives of
the world's birds Bird Love looks at the extraordinary range of
mating systems in the avian world, exploring all the stages from
courtship and nest-building to protecting eggs and raising chicks.
It delves into the reasons why some species, such as the wattled
jacana, rely on males to do all the childcare, while others, such
as cuckoos and honeyguides, dump their eggs in the nests of others
to raise. For some birds, reciprocal promiscuity pays off: both
male and female dunnocks will rear the most chicks by mating with
as many partners as possible. For others, long-term monogamy is the
only way to ensure their offspring survive. The book explores the
wide variety of ways birds make sure they find a mate in the first
place, including how many male birds employ elaborate tactics to
show how sexy they are. Gathering in leks to display to females,
they dance, pose, or parade to sell their suitability as a mate.
Other birds attract a partner with their building skills: female
bowerbirds rate brains above beauty, so males construct elaborate
bowers with twig avenues and cleared courtyards to impress them.
Looking at the differing levels of parenting skills across species
around the world, we see why a tenth of bird species, including the
fairy-wrens of Australia, have helpers at the nest who forgo their
own reproduction to assist the breeding pair; how brood parasites
and their hosts have engaged in evolutionary arms races; and how
monogamous pairs share-or relinquish-their responsibilities.
Illustrated throughout with beautiful photographs, Bird Love is a
celebration of the global diversity of avian reproductive
strategies.
Bird Talk delves into new scientific developments to reveal the
complexities of how birds make, learn, and use sound in a
bewildering array of songs and calls. The beauty of birdsong is one
of the joys of nature, and this book reveals how songs are learnt
and performed, why the quality of a male's repertoire can affect
his mating success, and how birds use song-matching and
countersinging in territorial disputes. Bird Talk illustrates how
birds communicate through visual signals too, from the dazzling
feathers of a Peacock to the jumping displays a Jackson's Widowbird
performs to show off his long tail. Plumage features such as the
red bill shield of a Pukeko can indicate dominance, and how
aggressive wing-waving is used to ward off impostors. Bird Talk
will help you understand how birds communicate in a range of
situations, whether in harmony or in conflict, providing essential
new insight into avian intelligence.
