Dedicated to the Understanding, Protection and Awareness of Birds in Toronto

The Tommy Thompson Park Bird Research Station (TTPBRS) was established in 2003 by Toronto and Region Conservation in 2003 and is dedicated to the understanding, protection and awareness of birds in Toronto.

TTPBRS is in Tommy Thompson Park (Leslie Street Spit) located at the foot of Leslie Street, south of Lake Shore Blvd, minutes from downtown Toronto.
The park is open to the public weekends and holidays from 9am-6pm April through October and 9am-4:30pm November through March.

Migratory Birds

Many migratory bird populations are declining because of habitat loss at nesting, migrating and over-wintering sites. To protect these species, we need to monitor them. Canada’s northern boreal forests are vital to migratory bird populations. However, these remote forests are mostly inaccessible to Breeding Bird Surveys. This problem led to the creation of Migration Monitoring as a way to keep tabs on the health of birds in the north. At TTPBRS, birds are counted daily during spring (April 1-June 9) and fall migration (August 5-November 12) through bird banding and surveys. In addition to the core Migration Monitoring Program, TTPBRS also conducts an annual monitoring program for migratory owls.

Breeding Birds

TTPBRS monitors breeding birds every year throughout the Greater Toronto Area (GTA). The impacts of urbanization on nesting birds in the GTA are a specific focus of our breeding bird monitoring efforts. Data from these programs help conservation agencies protect birds and their environments at local, national and international levels.


Ornithological research is another main objective of the station. We provide opportunities for students and professional researchers to study birds and to develop their skills. Staff and volunteers participate every year in various projects with researchers.


The close proximity of the research station to a major city affords us a unique opportunity to engage a large population at a site of global significance for birds. Education programs for students and the general public are a focus of the research station. Our curriculum based program, Winged Migration, is offered to grades 4, 6 and 7. Staff and volunteers also provide regular demonstrations for visitors and training opportunities for those interested in the study of birds.
