MSc Candidate (2013-present)

For my MSc, I am studying the effects of early-life acute stress on fitness in a population of Savannah sparrows breeding on Kent Island, NB. Using a combination of field experiments and observational data, I am examining the relationship between early life stress and subsequent survival during both the post-fledging and pre-migratory periods.  I am also fitting birds with geolocators during autumn migration to examine whether early life stress influences migratory behaviour. For my senior honours undergraduate thesis at Guelph, I experimentally assessed the capture-restraint protocol for estimating the acute stress response under natural conditions (see publication below).
