Previous studies show that, in birds, pineal melatonin is important for circadian rhythmicity, and circadian rhythms mediate photoperiodic effects. The effect of pinealectomy or melatonin administration in photoperiodic induction of testicular g[...]

Among birds there are considerable interspecific differences in all aspects of visual fields. However, it is hypothesised that the topography of the frontal binocular portion of fields are of only three main types, and their principal functions [...]

The tropics support some of the world's richest centres of species diversity and endemism, yet these biomes are now dangerously imperilled by anthropogenic change. If we are to avert, or at least mitigate, catastrophic loss of species in these a[...]

A prerequisite for understanding adaptation is to understand how populations respond to environmental heterogeneity. We chose the blue tit Cyanistes caeruleus and Mediterranean habitat mosaics which exhibit a large diversity of habitats for anal[...]

Decades of research have shown that exposure to social signals such as conspecific song enhances reproductive function in birds. How such signals are processed by the brain, and particularly how these signals are transduced into an endocrine res[...]

Life history theory predicts that seabirds will respond to reduction in food abundance by changes in behaviour or breeding effort, buffering adult survival. Empirical data show some support for this but also sometimes indicate a trade-off in whi[...]

The reproductive cycle of most birds is driven by the annual change in photoperiod, with birds cycling between the physiological states of photosensitivity, photostimulation and photorefractoriness. Comparative studies show that variation in bre[...]

Head-bobbing is a common and characteristic behavior of walking birds. While the activity could have a relatively minor biomechanical function, for balance and stabilization of gait, head-bobbing is thought to be primarily a visual behavior in w[...]

Squabbles and squawks are a common feature of avian family life, so it is no wonder that birds are model species for the study of parent-offspring conflict. But how much do these behaviours really tell us about the evolutionary conflicts of inte[...]

Intensification of agricultural practices over the last 50 years has resulted in the impoverishment of the wildlife associated with lowland farmland across much of Western Europe. This is perhaps best documented in birds. In England, populations[...]

Nonexcavators (secondary hole-nesters) are birds that critically depend on holes for nesting and roosting; the absence of holes renders habitat uninhabitable to them. In man-managed woods, their populations are known to increase with the provisi[...]
