Food chains culminating with temperate insectivorous passerines are well described, yet whether trophic webs can be site-specific remains a largely unexplored question. In the case of site- or habitat-specificity of food webs, stable isotope sig[...]

Wildlife species have been subject to control efforts throughout human history due to real or alleged human-wildlife conflicts. The Double-crested Cormorant Phalacrocorax auritus in the interior of North America is no exception, with recent popu[...]

Drivers of wildlife population dynamics are generally numerous and interacting. Some of these drivers may impact demographic processes that are difficult to estimate, such as immigration into the focal population. Populations may furthermore be [...]

The effect of changing climatic conditions on wild populations has been the subject of much recent research. Most attention has been on the direct effects of climate changes on species of lower trophic levels and on the negative consequences of [...]

Using long-term mark-resighting data acquired over 27years in continental France, we estimated demographic parameters and modelled the dynamics of a newly established population of Ospreys Pandion haliaetus using a life-history model. We then pe[...]

Tagging is essential for many types of ecological and behavioural studies, and it is generally assumed that it does not affect the fitness of the individuals being examined. However, the tagging of birds has been shown to have negative effects o[...]

Past tracking studies of marine animals have primarily targeted adults, biasing our understanding of at-sea habitat use toward older life stages. Anthropogenic threats persist throughout the at-sea ranges of all life stages and it is therefore o[...]

Density is known to be an important factor in population size regulation. Several mechanisms of density limitation have been identified in colonial birds. We studied competition in Common Terns Sterna hirundo to assess whether the factor limitin[...]

Atlantic Herring is a keystone species in several marine ecosystems, supporting intensive fisheries as well as many predators including seabirds. Biomass of this stock in eastern North America has declined considerably in recent years, potential[...]

Local differences in feeding conditions have been suggested as a cause of regional variation in seabird demography but multi-colony comparisons of diet are rare. In UK waters the main fish eaten by seabirds during the breeding season belong to t[...]

Supplementary feeding of birds, particularly in urban areas, is often associated with increased population size and fecundity. In the UK, the non-native Grey Squirrel Sciurus carolinensis is common in rural and urban habitats. It exploits supple[...]

There is compelling evidence that Afro-Palaearctic (A-P) migrant bird populations have declined in Europe in recent decades, often to a greater degree than resident or short-distance migrants. There appear to have been two phases of decline. The[...]

Thiessen polygons are often used to model territory characteristics. However, information about the quality of Thiessen polygon-based estimates is currently lacking. We used published data to investigate the match between Thiessen polygons and m[...]

In migratory bird species, juveniles normally have shorter and more rounded wings than adults. The causes of this age-specific difference in wing morphology, however, are largely unknown. Here, we used longitudinal data collected over 3years fro[...]

Head-bobbing is the fore-aft movement of the head relative to the body during terrestrial locomotion in birds. It is considered to be a behaviour that helps to stabilize images on the retina during locomotion, yet some studies have suggested bio[...]

The Red-headed Wood Pigeon Columba janthina nitens is endemic to the Ogasawara Islands, an oceanic island chain located 1000km south of the main islands of Japan. The subspecies is at high risk of extinction because of its small population size [...]

In recent decades, numerous studies have examined factors affecting risk of host nest parasitism in well-known avian host-parasite systems; however, little attention has been paid to the role of host nest availability. In accordance with other s[...]
