Contaminant Levels in Eggs of American White Pelicans, <em>Pelecanus erythrorhynchos</em>, from Chase Lake, North Dakota [PDF]

The Canadian Field-Naturalist, 2008
American White Pelicans (Pelecanus erythrorhynchos) are colonial nesters, making them susceptible to site-specific mortality factors. One of the largest known breeding colonies is at Chase Lake National Wildlife Refuge in North Dakota. In 2004, this colony suffered total reproductive failure.

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 ...
