Abstract:
... Incidental capture in fisheries (“bycatch”) is a major threat to global marine biodiversity, especially to those species with low fecundity, such as albatrosses. Efforts to reduce bycatch have been undertaken in industrial fisheries, but the scale of seabird interactions with artisanal or small-scale fleets remains largely unknown. The island of Torishima (Japan) is an important breeding site for ...

Fringillidae; Turdidae; bending strength; birds; eggs; nests; stems
Abstract:
... Bird nests can have various roles but all act as the location for incubation, so at least have to serve to hold and support the incubating bird and its clutch of eggs. Nest construction is species specific and the use of materials varies between different parts of the nest. At present we know very little about the role that these materials play in the structural characteristics of the nest. This s ...

Tetrastes sewerzowi; adults; birds; breeding; brood rearing; chicks; conservation areas; demography; females; habitats; life history; models; nesting sites; predators; prediction; probability; radio telemetry; China
Abstract:
... Reproductive activities can incur various costs to breeding individuals in birds. One cost is that reproduction decreases survival probabilities of attendant individuals, which may have a major effect on population demography. During brood rearing, adults of precocial species usually make extensive movements to lead their young to sites with adequate food resources and dense cover. However, few st ...

Abstract:
... Agricultural landscapes play an important role in biodiversity conservation. The Tree Pipit (Anthus trivialis) was once a widespread breeding bird in European farmlands. Today, however, its numbers are sharply declining in most European countries. The aim of our study was to compare territory densities of Tree Pipits in common pastures and control plots in the surrounding pre-alpine agricultural l ...

Abstract:
... The Pantepui region harbors one of the most distinctive endemic montane bird faunas in the Neotropics, and is located across the tepuis of northern South America. We made an extensive literature review to understand large-scale distribution patterns of birds in the Pantepui. The core avifauna of the tepuis is composed of 138 bird species, most forest-dwelling insectivores, of which 43 are endemic. ...

Abstract:
... Colonization of urban habitats requires physiological, behavioral and morphological changes in many species. This is well studied in the Common Blackbird (Turdus merula), one of the most common bird species in Europe. Former studies found that urban Blackbirds show decreased migratory behavior. However, it is still a matter of debate whether this is linked to morphological changes. According to Se ...

Abstract:
... Bird nest orientation is affected by environmental variables determined by their geographical position as well as microclimatic conditions. In closed-cup-nesting species, nests may be oriented to avoid adverse environmental extremes such as sun exposure, wind, and rainfall, although vegetal cover may provide extra protection generating random orientation patterns. Here, we assess nest entrance ori ...

Abstract:
... Most altricial birds remove their nestlings’ feces from the nest, but the evolutionary forces driving this behavior are poorly understood. A possible adaptive explanation for this could be that birds avoid the attraction of nest predators to their nests due to the visual or olfactory cues produced by feces (nest predation hypothesis). This hypothesis has received contrasting support indicating tha ...

Abstract:
... Qualitative and quantitative assessments of bird song repertoires are important in studies related to song learning, sexual selection and cultural evolution. Despite methods for automatic analysis, it is still necessary to engage in manual cutting, segmenting and clustering of bird song elements in many cases. Here, we describe a program, the Ficedula Toolbox, which has been made available for fre ...

Abstract:
... In Europe, woodland bird populations have been declining since at least the 1970s, and in Britain, around one third of woodland bird species have undergone declines over this period. Habitat change has been highlighted as a possible cause, but for some species clear evidence of this is lacking owing to an incomplete knowledge of the species’ habitat requirements. Here, we analyse national data to ...

Abstract:

Seasonal variation in migratory routes seems to be a common trait among many Afro-Palearctic migrants, but there are only few examples of species or populations which shift between entirely different flyways in autumn and spring. To identify non-breeding regions and seasonal differences in migration strategies we tracked Barn Swallows (Hirundo rustica) from a Baltic breeding population by light-le ...

Abstract:
... Greylag Geese (Anser anser, Anatidae) are associated with water throughout their life and are, therefore, frequently exposed to avian malaria vectors such as mosquitoes (Culicidae) and black flies (Simuliidae). Thus, they could serve as reservoir for avian malaria parasites (Haemosporida). We examined 143 blood samples from individually ringed geese in a sedentary flock in Stuttgart, southwestern ...

Abstract:
... Among many functions, bird nests protect eggs, developing young, and incubating adults from inclement weather. In Tree Swallows (Tachycineta bicolor), prior to and while females are incubating, males compete with rivals for feathers that they use to line nests. The thermal benefits hypothesis proposes that males add feathers to improve heat retention of nests. We tested this hypothesis on Tree Swa ...

Abstract:
... The post-fledging dependence period (PFDP) is one of the most critical stages in the life history of some avian species. Birds are particularly sensitive to mortality during this stage as they must learn essential skills, such as efficient locomotion, proficient food location and predator avoidance. Knowledge of the PFDP would provide valuable information for conservation management of endangered ...

Abstract:
... The Blue Tit Cyanistes caeruleus prefer to use nest boxes to raise their young rather than nests in natural tree cavities. However, nest boxes provide a warm, humid microclimate that is favourable to the growth of rich bacterial communities. In this study we investigated how the bacterial community developed throughout the breeding season and whether it had any effect on egg or nestling mortality. ...
