El comportamiento de las aves

Birds are intelligent and social creatures that display a wide range of behaviors (from siege and mimicry to mating and co-rearing chicks). Why do they behave as they behave? Shedding light on the singular acts of birds through examples of species from around the world, The Behavior of Birds presents fascinating accounts of their private lives, all explained in an evolutionary context. We will find out how birds search for food, from feeding tactics, means and theft. We will learn about the rituals of celebration through the system of preferences, rivalry, courtship and pairing; family conflicts that arise between parents, children and siblings; and the stresses and strains of the clutch, such as territorial defense, nepotism, and relationship sabotage. We'll see how birds respond to threats and dangers (using such unusual practices as whispering, specific alarm chirps, distraction ploys, and nest design against predators). We will also interpret how birds modify certain behaviors (cleaning, migrating, brooding, and shrinking) based on the weather. Illustrated throughout, this book explores the vast differences between individuals in personality and how large-scale scientific data is increasing our knowledge.
