Scavengers have potential to translocate infectious transmissible spongiform encephalopathy prions in their feces to disease-free areas. We detail methods used to determine if mouse-adapted scrapie prions remain infectious after passage though the digestive tract of American crows (Corvus brachyrhynchos), a common consumer of dead animals.

Begin with a suspension of avian pathogenic E. coli or APEC in growth media.APEC is a Gram-negative bacterium that infects poultry by entering through the respiratory tract.After breaching the mucosal layer, APEC adhere to epithelial cells, multiply locally, and disrupt the epithelial barrier to enter the bloodstream. The bacteria then spread to multiple organs, causing systemic infection.Add an equal volume of the bacterial suspension to each well of a multi-well plate containing increasing...

Herpesvirus of turkeys (HVT) is widely used as a vector platform for the generation of recombinant vaccines against a number of avian diseases. This article describes a simple and rapid approach for the generation of recombinant HVT-vectored vaccines using an integrated NHEJ-CRISPR/Cas9 and Cre-Lox system.

A method to preserve, detect and sequence RNA from Avian Influenza Viruses was validated and extended using natural faecal samples from birds. This technique removes the necessity of maintaining a cool chain and handling of infectious viruses and can be applied in a 96-well high-throughput setup.

Simulating Colonization and Extinction on Islands ExpandForm groups of three. One member of the group will simulate colonization by throwing balls into the groups of cups representing the islands. Another will simulate extinction by rolling dice to randomly remove balls from the cups. The third group member will record the data. Take time to familiarize yourself with the four island stations. NOTE: There are two large islands with 12 cups and two small islands with 6 cups. Two of the stations...
FAQs
Air sacs work with the lungs to support the efficient respiratory system required by birds’ high metabolic demands. This arrangement helps sustain physiological activity associated with flight and other energy-intensive functions. In biology, examining this respiratory system explains how avian physiology supports demanding lifestyles and distinguishes birds from vertebrates with less specialized respiratory adaptations.
Feathers and lightweight skeletons form part of the structural adaptations associated with flight in avian species. Their importance reflects how anatomy can be shaped by functional demands, linking body form with movement and energy use. Studying these traits helps biologists interpret how avian species are adapted to their environments and how their anatomical features relate to evolutionary change.
Endothermy allows avian species to maintain internally regulated body temperatures while carrying out activities that require substantial energy. Combined with efficient lungs and air sacs, this physiological strategy supports the demands of active lifestyles. Its study helps biology researchers connect internal physiology with behavior, habitat use, and the ecological roles birds perform in different environments.
Reproduction in avian species typically includes internal fertilization followed by development within hard-shelled eggs. These processes connect reproductive biology with the structures and life-history patterns observed in birds. Investigating them gives researchers a basis for comparing avian reproduction across species and for understanding how reproduction contributes to population persistence and evolutionary study.
Avian research examines migration, behavior, and evolution as connected areas of biology rather than as isolated traits. Observing these subjects can reveal how birds move through environments, interact with ecological conditions, and change across evolutionary history. The resulting knowledge supports broader interpretations of biodiversity, population patterns, and responses to environmental change.
Avian species can indicate habitat quality because changes in bird populations or communities may reflect changing environmental conditions. This makes birds useful subjects for ecological assessment, alongside their value in biodiversity research. Information from avian studies can help identify habitat concerns, guide wildlife management, and support decisions intended to protect threatened populations.
Avian research informs conservation by linking bird biology with biodiversity protection, wildlife management, and the safeguarding of threatened populations. Birds also have relevance to disease transmission, so studying them can contribute to understanding potential wildlife health concerns. Together, these applications extend avian biology beyond species description toward environmental monitoring and practical population protection.
