Current Graduate Students
Olivia Wilson - Master's student
University of Northern British Columbia, co-supervised with Dr. Erin Baerwald
I received my B.Sc. in Biology from McMaster University in Hamilton Ontario. I am now completing my M.Sc. in Natural Resources and Environmental Studies at the University of Northern BC. My current project uses trail cameras to study the abundance and occupancy of free-roaming domestic cats in the South Okanagan Valley. I have placed trail cameras in urban, peri-urban, protected, and agricultural areas from March to December 2022 to help identify habitats that cats like to associate with and if cats occur in areas with species at risk or areas of high bird abundances. I have also placed trail cameras outside of bat roosts to examine cat behaviour and predation events.
Vanessa Hum - Master's student
Simon Fraser University, co-supervised with Dr. David Green
At the end of 2021, I completed my BSc. in Environmental Science minoring in Biology and Chemistry at Carleton University. During my honours thesis researching volunteering in the environmental sector, I discovered an organization that strives to reduce bird mortality from window collisions, Safe Wings Ottawa. I eventually led a few unique projects that combined both my passions for art and science. I designed and illustrated bird-friendly murals at high risks sites in the Ottawa area. Creating bird-friendly mural allows for science communication and education, while reducing window collisions. These projects led me to my current research for my MSc. at Simon Fraser University. I am evaluating bird collisions with windows at SFU’s Burnaby Campus through year-round collision monitoring, point counts and carcass persistence trials. I hope to evaluate species vulnerability, seasonal variability and determine the variables high-risk facades. I believe my research findings can aid in implementing building policy and solutions to reduce future window collisions.

I completed my B.Sc. in Zoology at Laurentian University in Sudbury Ontario. Following this, I was accepted to the University of Guelph where I am now studying domestic cats as a part of my M.Sc. research in the Integrative Biology (One Health) program. Domestic cats are one of the most popular pets worldwide, providing companionship for millions of people. However, when it comes to cat care there is a flashpoint of controversy surrounding whether owners should provide their pet with unsupervised outdoor access. While an outdoor lifestyle can be beneficial because cats can get more exercise and are able to engage in a more natural behaviour, there are concerns for their predation on native wildlife, welfare, and pathogen transmission among other cats, people and wildlife. To determine the costs and benefits of providing unsupervised outdoor access will involve understanding the health consequences to both cats and their owners and the impacts cats can have on native biodiversity. For this research, I propose to obtain this critical information by using newly developed animal-borne cameras called Catcams. These lightweight cameras attach to the cat’s collar and can give insight into how cats interact with their environment, by providing a first-person perspective of their world. The results will provide the first estimates of outdoor cat welfare risks and predation rates in Canada, throughout the annual cycle and during both the day and night.
Jonathan Chu - PhD Student
University of Guelph, co-supervised with Dr. Ryan Norris
I attended the University of Toronto for both my BSc. and MSc where I studied avian movement ecology. I was interested in how flight efficiency affected both migration and dispersal movements, and harnessed community science and museum data to approach these questions. For my PhD I’m excited to explore the role outdoor cats play in urban ecosystems. Understanding the dynamics of native species and non-native species in urban ecosystems is of ecological importance, particularly in the case of outdoor cats as they are an important companion animal. CatCams, animal-borne cameras attached to cats, presents the opportunity to answer some of the open questions regarding outdoor cats while also incorporating the participation of the community. I plan to explore deep learning approaches to automate the processing of footage captured by CatCams, so that ecologically relevant footage can be quickly accessed. With this footage I plan to estimate the predation rates imposed by cats on native wildlife and explore how these predation rates change through habitats. This information will help clarify the role outdoor cats play in urban ecosystems and help inform management strategies so that both wildlife and cats are protected.

Estimating habitat characteristics associated with the abundance of free-roaming domestic cats across the annual cycle

I completed my B.Sc. in Honours Biology at McMaster University and my M.Sc. at the University of Guelph. For my M.Sc., I examined how free-roaming cat abundances change seasonally. Free-roaming cats include any domestic cat with unsupervised access to the outdoors (including owned and unowned cats). These animals can have negative impacts on the ecosystem. However, determining the impacts of free-roaming cats on wildlife requires understanding where cats are found and how cat abundances vary across the year. We used trail cameras in rural and urban areas in southern Ontario, Canada, to accomplish this goal. We found that cats were more likely to be found near buildings and away from agriculture in the spring/summer. In the fall/winter, cats were found near major roads and away from coyotes. Our research shows that the development of management strategies aimed at reducing free-roaming cats in temperate areas should incorporate seasonal and landscape patterns.
