Recent insect abundance declines may have affected populations of insectivorous bird species but evidence for this is limited. Here, we use spatially overlapping 29-year time-series of aerial insect biomass and Barn Swallow Hirundo rustica numbe[...]

Mixed-species flocks of birds involve species with different roles and foraging strategies and are ubiquitous in forest environments. Species roles can broadly be categorized into leaders that attract others to form the flock, as well as lead th[...]

Post-mating courtship displays are often viewed as forms of sexual selection that allow individuals to assess fitness benefits from their mates based on honest signalling. However, display costs are not always easy to identify and quantify. Befo[...]

Population-level estimates of offspring sex ratios in birds typically approximate parity whereas biased ratios within nests are not uncommon. In sexually dimorphic raptors, the costs and relative fitness benefits of rearing male and female proge[...]

In long-lived seabirds, social monogamy and mate and site fidelity are common due to the cost entailed by site change and divorce such as delayed laying or reduced reproductive success. We used 13 years of monitoring data from marked Long-tailed[...]

Maculation on avian eggshells has the potential to serve as an identity signal, and this information may help females recognize their eggs/nest or reject foreign eggs laid by hetero- or conspecific brood parasites. Recognizing eggs could be adap[...]

Annual survival is a key demographic trait influencing population growth and viability. Variability among species in annual survival tends to reflect different life history trajectories. In adult birds, greater annual survival has been shown to [...]

Masquerading is a camouflage strategy in which the prey (here, the nests) have visual similarities to inedible objects or structures present in the surrounding environment to avoid correct identification by visually oriented predators. Here we i[...]

An understanding of feather moult, an important process in the life cycle of birds, lags behind that of other avian life-history events. This lag includes a lack of scientific attention, but surprisingly also a lack of basic knowledge regarding [...]

Staying or leaving the natal site is a decision that not only affects the individual but may have profound implications at the population level. Many studies have analysed natal philopatry in passerines, albeit mostly migratory species in the no[...]

Split moult is a relatively rare adaptation to cope with time constraints in the annual cycle, although less rare than previously thought. This moult pattern mainly occurs among long-distance migrants but also among some northern species winteri[...]

In common with many other insectivorous birds, the Common Swift Apus apus is undergoing population declines, with an estimated 57% reduction in abundance between 1995 and 2017 in the UK. The ultimate drivers of this decline are poorly understood[...]

Lesser Kestrel Falco naumanni (Fleischer, 1818) populations have been one of the best monitored bird populations in Spain over the last 70 years. These populations suffered a sharp decline between the 1950s and 1990s. Since then, periodic census[...]

Human activities can be noisy, especially in urban areas, and affect animals detrimentally. Traffic noise may interfere with acoustic communication through masking and may yield noise-dependent modification of acoustic signals. Such vocal flexib[...]

Many bird species produce low-amplitude acoustic signals, known as soft songs, which are widely believed to function primarily in aggressive interactions. However, there are surprisingly few experimental studies that have examined whether soft s[...]
