A diagram from my poster illustrating the concept of sound localization. The black dots are microphones; the blue bird is the sound source; the relative delay of a sound arriving at the four microphones can be used to estimate the bird’s location with about 1m of accuracy.

This past weekend, I attended the Alberta Chapter of the Wildlife Society Conference in Lethbridge, Alberta. This was my first time attending a conference focused on something other than birds, and I had a fantastic time. I met lots of interesting people – many from Alberta, some from outside the province. I gave a poster presentation entitled “Localization of bird songs to assess responses to oil well sites”. Continue reading

A bit of winter field work!

I recently returned from two trips to Northeastern Alberta to conduct some winter field work. The project is the Master’s project of Bayne lab member Jeremiah Kennedy. The goal is to survey for owls in Alberta’s boreal forest, understand their habitat preferences, and investigate whether small owls avoid or alter their behaviours in response to large owls. Species of interest include Boreal Owls, Great Horned Owls, and Barred Owls, to name a few.

Because owls breed in March and April, we had to put the recording units out in February to ensure we didn’t miss their peak vocal activity – hence the snowmobiles. I spent most of my days snowshoeing to far-off locations in thigh-deep snow: hard work – and my hip flexors gave me some grief – but it was a great experience!
