This monograph summarizes the results of studying passerine migration, mainly that of long-distance nocturnal migrants. Migratory stopovers and migratory flights are shown to be closely interconnected. The main quantitative parameters of stopovers, i.e., their duration, fuel deposition rate and overall energy efficiency, govern the potntial range of migratory flights. The quantitative energetic parameters of stopovers should not be studied separately from the stopover behaviour of birds, especially from their habitat selection and use and their spatial behaviour. The energy costs of migratory flight in species adapted for migration are significantly lower than hitherto assumed. A critique of optimal migration theory is presented and a qualitative model of stopover behaviour of migrating passerines is put forward. The monograph represents a valuable resource for ornithologists, zoologists, ecologists, conservationists, and students of biology.

A vivid, eye-opening view of why birds behave the way they do Birds are intelligent, sociable creatures that exhibit a wide array of behaviors-from mobbing and mimicking to mating and joint nesting. Why do they behave as they do? Bringing to light the remarkable actions of birds through examples from species around the world, Understanding Bird Behavior presents engaging vignettes about the private lives of birds, all explained in an evolutionary context. We discover how birds find food, relying on foraging techniques, tools, and thievery. We learn about the courtship rituals through which birds choose, compete for, woo, and win mates; the familial conflicts that crop up among parents, offspring, and siblings; and the stresses and strains of nesting, including territory defense, nepotism, and relationship sabotage. We see how birds respond to threats and danger-through such unique practices as murmurations, specific alarm calls, distraction displays, and antipredator nest design. We also read about how birds change certain behaviors-preening, migration, breeding, and huddling-based on climate. Richly illustrated, this book explores the increasing focus on how individual birds differ in personality and how big data and citizen scientists are helping to add to what we know about them. Drawing on classic examples and the latest research, Understanding Bird Behavior offers a close-up look at the many ways birds conduct themselves in the wild.--
