Ph.D. position: University of Saskatchewan

Comparing movements, behaviour, survival and reproductive success in dabbling ducks fitted with tracking devices using different attachment techniques

Description: A Ph.D. studentship is available with Dr. Mitch Weegman in the Department of Biology at the University of Saskatchewan ( The student will use state-of-the-art tracking devices deployed on mid-continent mallards to compare movements, behaviour, survival and reproductive success of birds using harness, anchor/suture and implant attachment techniques, and geolocators.

This project is an international partnership among the Canadian Wildlife Service, Delta Waterfowl Foundation, Ducks Unlimited Canada, Louisiana Department of Wildlife and Fisheries, and University of Saskatchewan. Our project goals are to (1) Deploy Global Positioning System-acceleration (GPS-ACC) tracking devices on 35 wild mallards per attachment technique, and geolocators on 150 wild mallards as a control group, per year for two years (totaling 280 GPS-ACC tracking devices and 300 geolocators), (2) Compare movements, behaviour, survival and reproductive success of tagged birds within and among treatments relative to a control group, (3) Assess retention of anchor/suture design in wild birds, and (4) Develop a reproducible framework to evaluate effect sizes of movement, behaviour, survival and reproductive success with varying frequency of GPS and ACC data, as well as sample size for each attachment technique.  

Our team will deploy GPS-ACC devices and geolocators on mid-continent mallards in Aug-Sept 2022, as year 1. We anticipate collation of millions of data points providing examples of individual decision-making. While GPS-ACC tracking devices have become common tools across animal ecology, and to some extent negative effects of devices on survival and reproductive success have been shown in a variety of animals, there have not been recent evaluations to contextualize data gained and inform operational monitoring programs/conservation planning. The student will have opportunities for field work in North Dakota and Saskatchewan, and engage in novel ecological modelling and collaboration among other projects using GPS-ACC devices to study the full annual cycle in migratory birds.  

Prerequisites: Ideal candidates will have an undergraduate and master’s degree in statistics, ecology or a closely related field, and interpersonal skills to lead discussions among collaborators. Preference will be given to those with a strong quantitative background (e.g., experience with Program R, Bayesian methods), knowledge of migratory bird ecology and management, and field skills (e.g., capturing and handling birds). Students must have a valid driver’s license. The successful applicant will be expected to publish manuscripts in peer-reviewed journals and present papers at scientific meetings.  

Salary and benefits: $30,000 Canadian per year plus compensation for tuition and fees.  

Start date: January 2023  

Last date to apply: 9 Sept 2022 or until a suitable candidate is selected
