The developmental stress hypothesis posits that the honesty of bird song is maintained by costs incurred during development, rather than at the time of adult song production. Song is learned, and the neural systems underlying song learning and p[...]

Over 90% of birds breed in socially monogamous partnerships. Among monogamous passerines, species vary from those with extra-pair copulations and short-term partnerships to others with exclusive and long-term partnerships. Study of long-term mon[...]

For a migratory bird, the costs and benefits of utilizing a given migratory strategy vary according to the biotic (e.g., physiology) and abiotic (e.g., weather) constraints it experiences throughout the year. In the New World, closely related sp[...]

Worldwide, populations of a diverse array of bamboo-specialist birds must respond to the life cycles of typical woody bamboos, which include a long vegetative phase, a short period in sexual reproduction (seeding), and a short period dead. While[...]

Males of the Golden-collared Manakin (Manacus vitellinus) perform elaborate courtship displays that are among the most spectacular in the animal kingdom. During an extended breeding season, male manakins aggregate in leks, where each male clears[...]

A complex social life serves as one of the main driving forces behind the evolution of higher cognitive abilities in vertebrates. In birds, however, data are primarily derived from captive animals, which strongly contrast with free-flying birds [...]

Birds are the most diverse and largest group of extant tetrapods. They show marked variability, yet much of this variation is superficial and due to feather and bill color and shape. Under the feathers, the skeleto-muscular system is rather cons[...]

There is a growing body of evidence from across animal taxa that exposure to elevated levels of glucocorticoids during development can have profound long-term effects upon physiological and behavioral phenotypes. Several avian studies have revea[...]

Seventy-three of the 280 species of Galliformes are at risk of extinction, and all of them are threatened by human factors (mainly hunting and deforestation). Reintroduction is increasingly proposed as a conservation measure, although there is l[...]

Sensory ecology investigates the information that underlies an animal's interactions with its environment. A sensory ecology approach provides a framework in which to investigate a wide range of topics in ornithology. This review provides a rang[...]

The hemispheres of the avian brain are specialized to carry out different functions. Since each eye sends its input mainly to the contralateral hemisphere, birds respond differently to stimuli seen with the left eye than they do to stimuli seen [...]

Male song sparrows (Melospiza melodia) are territorial year-round. However, neuroendocrine responses to simulated territorial intrusions (STI) differ between breeding (spring) and non-breeding seasons (autumn). In spring, exposure to STI leads t[...]

Climate change has profound ecological effects in birds, with the clearest effect a shift in timing, or phenology, of avian reproduction. To assess the consequences of these shifts, we performed a literature search and compared the rates of phen[...]

Melatonin regulates diurnal locomotor rhythms in birds as well as in other vertebrates, but the molecular mechanism by which melatonin regulates locomotor activity is poorly understood. Here, we summarize new findings showing that 7 alpha-hydrox[...]

Migrant species express wide varieties of movement strategies that closely mirror patterns of resource distribution. Resources can vary predictably in space and time (e. g., seasonal peaks of productivity in temperate regions) or can be unpredic[...]

Although most bird species avoid agricultural areas, nearly a third of all birds regularly to occasionally use such habitats, often providing important ecosystem services like pest control, pollination, and seed dispersal. Combining literature r[...]

Birds show high levels of steroid synthesis in the brain. Steroid biosynthesis in the brain can provide a mechanism for local and rapid changes in steroid levels in particular brain regions. Neural steroidogenic enzymes are regulated on both sho[...]

Even large fragments of tropical forest lose bird species over time. The speed of disappearance and permanence of these losses depend on a variety of factors, but the pattern of species loss appears more universal. We still do not understand the[...]

Our understanding of avian migration has progressed significantly, yet the selective conditions that favor the arrival of males before females at the site of reproduction remain largely unclear. Here, we review the leading adaptive hypotheses fo[...]

Sexual selection has shaped many traits involving communication, behavior, morphology, and reproductive strategies. Sexual communication in the Blue-black Grassquit Volatinia jacarina involves an iridescent, nuptial plumage and the exhibition of[...]

This paper is concerned mainly with the differences between obligate and facultative migration in birds. Obligate migration is considered "hard-wired", in that the bird seems pre-programmed to leave its breeding area at a certain time each year,[...]

I have collaborated with Asian and American scientists on satellite-tracking the migration of birds in East Asia for nearly 20 years. We have tracked the migration of about 20 bird species, including cranes, storks, swans and hawks. We have used[...]
