Evaluation of radiotagging techniques and their application to survival analysis of Red-legged Partridge Alectoris rufa chicks [PDF]
A better knowledge of chick survival rates is required to enable understanding of the population dynamics of gamebirds and to develop management measures to conserve their populations.

This study found that over 10% of wild birds in Lahore, Pakistan, carry antibodies for Toxoplasma gondii, a parasite that can cause serious illness in humans and animals. Birds like lapwings and silver bills showed especially high antibody rates. Improved monitoring is needed to better understand risk dynamics in Pakistan.

Evolution of a cluster of innate immune genes (β-defensins) along the ancestral lines of chicken and zebra finch [PDF]
BACKGROUND:Avian beta-defensins (AvBDs) represent a group of innate immune genes with broad antimicrobial activity. Within the chicken genome, previous work identified 14 AvBDs in a cluster on chromosome three.

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations
Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

Hunting and fishing harvest data collection: a horizon scanning exercise from the French context
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds [PDF]
The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...

ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.
