Breeding ecology and dispersal decisions of Canada jays

Canada jays are year-round residents of the boreal forest and rely on perishable cached food for overwinter survival and late-winter reproduction. Impressively, Canada jays breed in late-winter when no other food is available, thus making their caches critical for individual fitness. I am interested in the causes and consequences of dispersal movements in juveniles and adults. I am using a combination of long-term data and radio-telemetry (via ground and air) to quantify the dispersal patterns and the costs and benefits of delayed dispersal in juvenile jays. I am also using the long-term re-sighting data to examine the demographic causes and consequences of breeding dispersal.

Gull nesting and foraging ecology in relation to urbanization

Gulls are well-suited for studies assessing the impacts of urbanization on wildlife since they show highly plastic behaviour and thrive in various environments along the coast and inland. I am interested in how urbanization impacts the foraging and breeding ecology of herring and great black-backed gulls at both the individual and colony-level. I am using microbial (i.e. heavy metal contaminants & microbiome) and spatial (i.e. GPS tracking) analyses to assess the effects of urbanization on gull foraging behaviour and subsequent health consequences. Additionally, I am interested in how microplastics in the marine environment influence breeding behaviours of gulls.

Ontogeny of food-caching in Florida Scrub-Jays

Florida Scrub-Jays are cooperative breeders endemic to the oak-scrub habitat of Florida, a fire-mediated ecosystem. During the fall, family groups of Florida Scrub-Jays harvest and scatter-hoard thousands of acorns. Most caches are placed in the sand or under leaf litter, grass, or palmettos. However, these caches are susceptible to degradation due to moisture in the soil. I am interested in the ontogeny of caching behaviours in Florida Scrub-Jays and how social hierarchies influence caching preferences in juvenile jays. Additionally, I am interested in how food-caching preferences can lead to expansion of oak-scrub habitat.
