The reproductive success of a male bird is often correlated with measurable traits that predict his intrinsic quality. Females are thought to base their selection of mates on the latter's 'quality' in order to gain their 'good genes'. Male Austr[...]

Many bird species flock to forage on newly mown grass swards. Several potential benefits are offered by such swards, including increases in prey availability (flush of foliar prey, reduced physical obstruction to surface and soil prey) and a for[...]

Long-distance migrants have evolved complex strategies for the timing of their annual moult, fattening and migration cycles. These strategies are likely to vary at different stages of a bird's life. Ringing data on 6079 Grey Plovers Pluvialis sq[...]

With reference to models predicting patterns of reproduction in multi-brooded species, I analysed some of the factors potentially affecting the number of breeding attempts per season made by female Black Redstarts Phoenicurus ochruros in the cen[...]

Social interactions are thought to be an important determinant of food hoarding behaviour in birds. Theoretical work predicts that subordinate birds should cache more to offset losses to dominant birds. However, empirical support for this predic[...]

Comparative large-scale roadside counts (8353 km), through Burkina Faso, Mali and Niger, conducted in 1969-73, were repeated 30-35 years later with the same observer and methodology and at the same season. The transect was divided into three geo[...]

Feral Pigeons Columba livia live in almost every city in the world and are often a problem because of their large numbers. Knowledge of the spatial use of the city by Pigeons is important for population control management. Previous studies have [...]

Eggs untended during the laying phase can lose viability if exposed to high temperatures, such as those common at lower latitudes and late in the nesting season. The egg-viability hypothesis states that constraints on viability during the laying[...]

Variation in rearing conditions, due either to parental or to environmental quality, can result in offspring of different quality (e.g. body condition, immune function). However, evidence is accumulating that egg size and composition can also af[...]
