Stutchbury lab does research on the conservation biology and ecology of
migratory songbirds in
pioneered the use light level “geolocators” to track individual
songbirds to their wintering grounds and back.
Geolocators are a now a widely used and critical conservation tool
for songbirds that allows us to identify the core wintering regions
and stopover sites, and hence potential threats. We have
accumulated large geolocator data sets, across the breeding range,
for both Wood Thrushes (>100 birds) and Purple Martins (>250
birds) that allow us to test many questions about migration
ecology and conservation.

We have tracked Wood Thrushes from sites across the breeding and
wintering range to study the carry-over effects from breeding to
fall migration, the flexibility in timing of departure from
Central America, the differences in spring migration schedule
between naive juveniles and experienced adults, and to create a
migratory connectivity map for the species.

Purple Martin Migration
collaboration with the Purple Martin Conservation Association, we have
teamed up with researchers, biologists, and volunteers across North
America to track hundreds of purple martins. We have identified the core
wintering sites occupied in Brazil, tested whether populations could
migrate earlier in the warmest year on record, and mapped how birds
navigate the Gulf of Mexico barrier in fall. We are currently studying
how landscape cover and rainfall influences intra-tropical migration and
the extent of individual flexibility in timing and routes.

Direct Impacts of Humans on
MSc student Sean Chin is
conducting a study of window-collision mortality on the York U campus to
better quantify overall mortality and to identify potential
building in need of mitigation.
New research projects have
begun in collaboration with Dr. Christy Morrissey (U Saskatchewan) to
study the impacts sub-lethal effects of pesticides on songbird migration
and nesting behaviour.
Breeding and Winter Ecology of
ecology of songbirds, on both the breeding and wintering grounds, is
fundamental to developing informed conservation strategies.
We have worked with the Purple Martin Conservation Association to
analyze long-term term data sets to estimate juvenile and adult
students Pat Kramer & Cassandra Silverio are currently completing
their dissertations on how extra-pair
paternity, and parasite loads, affect reproductive success and survival in
Purple Martins. Earlier radio-tracking studies estimated fledgling
and juvenile survival in Eastern Loggerhead Shrikes, Hooded Warblers and
