60 million is a big number that suggest cats have a negative impact of birds in Canada. Cat owners, municipalities, wildlife managers and researchers all have a part to play in ensuring our environments benefit wildlife, people and cats alike. stewardshipcentrebc.ca/cats-and-bir...

There are still no direct measures of predation rates from cats in Canadian areas, but as followers of me are aware, we are working and will publish novel predation rates from Canadian localities soon!

There is still a lot of uncertainty, we need more estimates of how many cats there are outside, especially from rural areas and of unowned cats.

We also incorporated many new predations rate studies that have adjusted predation rate parameters in the model to be slightly lower.

In 2013, it was estimated that cats kill between 105-348 million birds. Our updated estimate does NOT mean cats kill fewer birds now. The discrepancy comes from lower cat population estimates that we derived from primary field estimates rather than shelter intake and survey data originally used. 2/6

How many #birds are killed by #cats in Canada? Between 19-197 million! This is the main result from my first chapter of my PhD thesis just published in Avian Conservation and Ecology. ace-eco.org/vol20/iss2/a...

Another trip around the sun over ! Research/PhD life highlights from 2024!

1. Completing my field season in the Okanagan, BC
2. Winning best student talk at NACCB 2024
3. Organizing a FREED field excursion for BIPOC students
4. All the birds!
5. A certain scholarship that rhymes with sea-gee-es-dee

Welcome to the newest spot to get your CatCam updates! I am a PhD candidate studying the impact of outdoor cats on wildlife by attaching animal-borne cameras on owned domestic cats! Hopefully I'll be more disciplined and provide more research updates here than over at that last website!
