Genetic differences between willow warbler migratory phenotypes are few and cluster in large haplotype blocks Open
It is well established that differences in migratory behavior between populations of songbirds have a genetic basis but the actual genes underlying these traits remains largely unknown. In an attempt to identify such candidate genes we de …

How cuckoos find and choose host nests for parasitism Open
Lay Summary We provide experimental evidence to confirm that the common cuckoo (Cuculus canorus) locates its Oriental reed warbler (Acrocephalus orientalis) host nests by monitoring the activities of nest owners. Cuckoos distinguished betw…

Migratory birds as vehicles for parasite dispersal? Infection by avian haemosporidians over the year and throughout the range of a long‐distance migrant Open
Aim The role of migratory birds in the spread of parasites is poorly known, in part because migratory strategies and behaviours potentially affecting transmission are not easy to study. We investigated the dynamics of infection by blood pa…

Causes and consequences of spatial variation in sex ratios in a declining bird species Open
Summary Male‐biased sex ratios occur in many bird species, particularly in those with small or declining populations, but the causes of these skews and their consequences for local population demography are rarely known. Within‐species var…

Correlates of bird collisions with buildings across three North American countries Open
Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites with s…

Concentration of a widespread breeding population in a few critically important nonbreeding areas: Migratory connectivity in the Prothonotary Warbler Open
One of the greatest challenges to informed conservation of migratory animals is elucidating spatiotemporal variation in distributions. Without such information, it is impossible to understand full-annual-cycle ecology and effectively imple…

Genomic variation across the Yellow-rumped Warbler species complex Open
Populations that have experienced long periods of geographic isolation will diverge over time. The application of high-throughput sequencing technologies to study the genomes of related taxa now allows us to quantify, at a fine scale, the …

Telecoupling framework for research on migratory species in the Anthropocene Open
Migratory species are an important component of biodiversity and provide essential ecosystem services for humans, but many are threatened and endangered. Numerous studies have been conducted on the biology of migratory species, and there i…

Earlier and slower or later and faster: Spring migration pace linked to departure time in a Neotropical migrant songbird Open
Migratory birds travel vast distances and the timing of migratory flights can affect survival and the ability to reproduce. For Neotropical migrant songbirds, early spring departure from wintering sites, early arrival to the breeding groun…

Interspecific social information use in habitat selection decisions among migrant songbirds Open
Lay Summary A late arriving migrant bird species (wood warbler) are attracted to simulated presence of an earlier arriving species (chiffchaff). This habitat selection strategy was previously only described for migrants attracting to resid…

Factors controlling the migration phenology of Siberian Phylloscopus species Open
The timing of annual events in migratory species is determined by the position of breeding and wintering grounds, length of the breeding season, the occurrence of their preferred diet or the timing of moult in birds. Previous studies found…

Combining bioacoustics and occupancy modelling for improved monitoring of rare breeding bird populations Open
Effective monitoring of rare and declining species is critical to enable their conservation, but can often be difficult due to detectability or survey constraints. However, developments in acoustic recorders are enabling an important new a…

Interspecific competition between resident and wintering birds: experimental evidence and consequences of coexistence Open
The contribution of interspecific competition to structuring population and community dynamics remains controversial and poorly tested. Interspecific competition has long been thought to influence the structure of migrant–resident bird com…

Warmer April Temperatures on Breeding Grounds Promote Earlier Nesting in a Long-Distance Migratory Bird, the Prothonotary Warbler Open
Global climate change and warming are altering hemispheric and local weather patterns. Altered weather patterns have great potential to affect the phenology of life history events, such as the initiation of breeding in organisms that repro…

Rescue behaviour in a social bird: removal of sticky ‘bird-catcher tree’ seeds by group members Open
Rescue behaviour is a special form of cooperation in which a rescuer exhibits behaviours directed towards averting a threat to an endangered individual, thereby potentially putting itself at risk. Although rescue behaviour has been well-do…
