Swifts Apus apus are renowned for their fast flight manner which has fascinated people in all times. However, previous studies of swifts in flight during migration and roosting flights have shown that the birds operate over a narrow range of fli[...]

Phenotypic flexibility is a phenomenon where physiological functions in animals are reversibly adjusted in response to ecological constraints. Research usually focuses on effects of single constraints, but under natural conditions animals face a[...]

Survival is a key demographic parameter in bird populations yet remarkably little is known about the seasonal pattern of survival. Mortality may increase as a result of breeding behaviour, harsh environmental conditions, resource limitation or a[...]

Identification of interspecific hybrids is often a subject of primary concern in the development of conservation strategies. Here we performed a genetic analysis combining mitochondrial DNA (mtDNA), microsatellites and single nucleotide polymorp[...]

We used PCR to screen for the presence of haemosporidian parasites (Phylum: Apicomplexa; Order: Haemosporida) in avian blood samples, and sequenced the parasite mitochondrial cytochrome b gene from infected hosts, to study patterns in the preval[...]

Estuarine mudflats, among the most important foraging grounds for waders during the non-breeding season, consist of complex mosaics of shallow pools and dry areas during low tide. In this study, we carried out close-range focal observations to d[...]

Microsatellites are commonly used molecular markers in phylogeography, and many view them as superior to mitochondrial DNA (mtDNA) gene trees. Being based on frequencies of alleles, and not gene trees, microsatellites exhibit the same analytical[...]

Among the various species that form mixed-species bird flocks, "nuclear species" are thought to be important in flock formation and maintaining flock cohesion. Such nuclear species have been noted to occur in large groups on their own and to lea[...]

Sexually dimorphic traits often signal the fitness benefits an individual can provide to potential mates. In species with altricial young, these signals may also predict the level of parental care an individual is expected to provide to shared o[...]

Two hybrid zones between subspecies of the Australian ringneck parrot (Psittacidae: Platycercus zonarius) were examined for morphological (plumage patterns) and cultural (learned contact flight calls) traits. Mensural traits and plumage patterns[...]

The correct identification of hybrids is essential in avian hybridisation studies, but selection of the appropriate set of genetic markers for this purpose is at times complicated. Microsatellites and single nucleotide polymorphisms (SNPs) are c[...]

Ring re-encounter data, in particular ring recoveries, have made a large contribution to our understanding of bird movements. However, almost every study based on ring re-encounter data has struggled with the bias caused by unequal observer dist[...]
