Seasonal changes in moult, body mass and reproductive condition in siskins Carduelis spinus exposed to daylength regimes simulating different latitudes [PDF]
Birds use change in daylength during the year to time events during their annual cycles. Individual Eurasian siskins Carduelis spinus can breed and winter in widely separated areas in different years.

ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Serological Evidence for Influenza A Virus Exposure in Wild Birds in Trinidad & Tobago
Migratory waterfowl and shorebirds are known to be important reservoirs for influenza A viruses (IAV) and they have been repeatedly implicated as causing avian influenza virus (AIV) outbreaks in domestic poultry flocks worldwide.

Phylodynamics of H5N1 Highly Pathogenic Avian Influenza in Europe, 2005-2010: Potential for Molecular Surveillance of New Outbreaks. [PDF]
Previous Bayesian phylogeographic studies of H5N1 highly pathogenic avian influenza viruses (HPAIVs) explored the origin and spread of the epidemic from China into Russia, indicating that HPAIV circulated in Russia prior to its detection there in 2005 ...

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Highly Pathogenic Avian Influenza H5N1 (HPAI/H5N1) Virus Search from Wild Birds in Ghana
Highly pathogenic avian influenza (AI) disease has occurred in many countries globally adversely affecting domestic poultry production. Ghana recorded her first outbreak of a highly pathogenic avian influenza (HPAI) in 2007 on a small scale commercial ...

The magnetite-based receptors in the beak of birds and their role in avian navigation [PDF]
Iron-rich structures have been described in the beak of homing pigeons, chickens and several species of migratory birds and interpreted as magnetoreceptors.

A neuro‐behavioural model of neophobia
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.
