The influence of floral resource availability on behaviour and dominance hierarchy of hummingbirds has seldom been investigated in open tropical environments. We evaluated the behavioural changes of hummingbirds associated with Palicourea rigida[...]

Farmland bird populations in Europe are shrinking, largely due to modern agriculture practices. In grasslands, the shift to early mowing is believed to be particularly responsible for this decline because it is interwoven with breeding time-a ch[...]

Bacteria have the potential to be important selective forces in the evolution of many aspects of avian biology, including nestling growth. We estimated abundances of two common gut bacterial types in birds (enterococci and Enterobacteriaceae) an[...]

Seabirds are effective samplers of the marine environment, and can be used to measure resource partitioning among species and sites via food loads destined for chicks. We examined the composition, overlap, and relationships to changing climate a[...]

Measuring circulating glucocorticoids is a widely used method to assess stress in animals. However, hormones must be sampled within the first few minutes of capture, which makes it difficult to discriminate between hormone baseline levels and th[...]

Differential migration reflects various constraints and selective forces on different individuals in a population, and has been explained by several hypotheses. Most previous studies about differential migration focused on only one aspect (e.g. [...]

Morphometric estimates of body condition are widely used by ornithologists, but which estimates work best is a matter of debate. We review morphometric approaches (body mass, ratio and residual condition indices, predictive regression models, fa[...]

In cooperatively breeding birds, breeders can adjust their parental care investment without affecting nestling survival probability and save energy to invest in other activities, such as feeding, mating or territory defense. Furthermore, helpers[...]

Differences in the ability to sustain chronic stress can underlie the variation in individuals' fitness directly or indirectly by impairing the expression of condition-dependent signals used in female mate choice. Therefore, understanding the ef[...]

Intensive agriculture, in which detrimental farming practices lessen food abundance and/or reduce food accessibility for many animal species, has led to a widespread collapse of farmland biodiversity. Vineyards in central and southern Europe are[...]

Between 2006 and 2008, 14 Montagu's Harriers (Circus pygargus) were tagged with satellite transmitters at their breeding grounds in NE Spain, recording a total of 18 autumn and 10 spring journeys. In both autumn and spring migrations, harriers m[...]

Increasing ecotourism activity in Argentine Patagonia has led to concerns about the effects of ecotourism on wildlife populations. Penguin breeding colonies are popular tourist destinations. While some species of penguins habituate to human visi[...]

The age at first breeding is an important demographic parameter in determining maximum growth rate, population size and generation time and is a key parameter in calculating the potential biological removal of birds. Albatrosses and petrels do n[...]

We investigated the effects of habitat structure and composition, rainfall and nest spacing on the productivity of an Eagle Owl Bubo bubo population in Piedmont, northern Italy, at 10 sites from 1996 to 2007. We modeled the effects of the above [...]

We reviewed information on nest sanitation (nest cleaning) by passerine birds because the act of cleaning nests is thought to be associated with egg rejection by hosts of brood parasites, and yet there has been no synthesis of the literature on [...]

The use of artificial nest boxes has led to significant progress in bird conservation and in our understanding of the functional and evolutionary ecology of free-ranging birds that exploit cavities for roosting and reproduction. Nest boxes and t[...]
