New methods for estimating the total wing area of birds. [PDF]

Ecol Evol, 2023
Estimating flight capabilities from wing shape is a powerful tool for the comparative analysis of dispersal in ecology and evolution. Here, we describe new methods for estimating the total wing area, which will allow for readily estimating wing aspect ratios and wing loadings for thousands of bird species. Abstract Dispersal is a fundamental process in

Descriptive Epidemiology and Phylodynamics of the "First Wave" of an Outbreak of Highly Pathogenic Avian Influenza (H5N1 Clade 2.3.4.4b) in British Columbia and the Yukon, Canada, April to September 2022. [PDF]

Transbound Emerg Dis
Highly pathogenic avian influenza (HPAI) is a viral disease that causes significant rates of morbidity and mortality in domestic poultry and wild birds, with occasional spillover into mammals, including humans. Beginning in November 2021, Canada experienced its longest and largest outbreak of HPAI in history. A portion of this outbreak (H5N1, clade 2.3.

Mitigating Risk: Predicting H5N1 Avian Influenza Spread with an Empirical Model of Bird Movement. [PDF]

Transbound Emerg Dis
Understanding timing and distribution of virus spread is critical to global commercial and wildlife biosecurity management. A highly pathogenic avian influenza virus (HPAIv) global panzootic, affecting ~600 bird and mammal species globally and over 83 million birds across North America (December 2023), poses a serious global threat to animals and ...

Bridging, Braiding, and Weaving Indigenous and Western Science to Understand and Make Predictions About Weather and Climate Change. [PDF]

Ecol Evol
This paper examines Indigenous weather science through a workshop with Indigenous Knowledge Holders, documenting traditional weather prediction methods and their responses to climate change and severe weather. Using the bridging, braiding, and weaving framework, it highlights the complementary nature of Indigenous and Western science.

Spatial and temporal variability of movements among sympatric salmonids in an unfragmented inland watershed. [PDF]

Trans Am Fish Soc
Abstract Objective Our aim was to determine the movement patterns of three abundant salmonids—Brown Trout Salmo trutta, Mountain Whitefish Prosopium williamsoni, and Rainbow Trout Oncorhynchus mykiss—in the Smith River watershed of Montana. Methods We tagged 7172 fish with passive integrated transponder (PIT) tags, monitored their movements past 15 ...

Large- and Small-Scale Climate Influences Spring Migration Departure Probability of American White Pelicans

Diversity, 2022
Endogenous (e.g., age and sex) and exogenous (e.g., climate and resource availability) factors influence avian migration phenology. However, little is known regarding the migration ecology of birds at the non-breeding grounds, including the American ...

SUSPECTED FENBENDAZOLE TOXICITY IN AN AMERICAN WHITE PELICAN (PELECANUS ERYTHRORHYNCHOS) [PDF]

Journal of Zoo and Wildlife Medicine, 2016
A wild-raised, 5.0-kg male American white pelican ( Pelecanus erythrorhynchos ) of unknown age presented for routine examination at both the start and completion of a 30-day quarantine period at a zoological park. Upon physical examination, the pelican was bright, alert, and responsive and in good body condition.

Seasonal Habitat Selection by American White Pelicans

Diversity, 2022
Resource utilization strategies of avian migrants are a major concern for conservation and management. Understanding seasonal habitat selection by migratory birds helps us explain the ongoing continental declines of migratory bird populations.

Seasonal variation and tracking of climate niche of a migratory bird

Global Ecology and Conservation, 2022
Migratory birds inhabit different areas during breeding and non-breeding seasons. Depending on the time of the year, they may utilize different resources available in seasonal habitats, but also are subjected to changing climate regimes during their ...
