The first edition of this list was compiled by C. Sean Blaney and was published as an appendix to his M.Sc. thesis (Blaney C.S. 1999. Seed bank dynamics of native and exotic plants in open uplands of southern Ontario. University of Toronto. https://tspace.library.utoronto.ca/handle/1807/14382/). It subsequently was formatted for the web by P.M. Kotanen and made available on the Koffler Scientific Reserve website (http://ksr.utoronto.ca/), where it was revised periodically to reflect additions and taxonomic changes. This second edition represents a major revision reflecting recent phylogenetic and nomenclatural changes and adding additional species; it will be updated periodically.

This property was donated to the University of Toronto in 1995. This list is based on observations at this site by C.S. Blaney, P.M. Kotanen, and many others beginning in 1997, supplemented with observations by property manager W. Fox between 1971 and 1998, and by an on-site banding program conducted by T. McKenzie and G. Reed since 2013. Phylogenetic classification and scientific and English nomenclature follow the American Ornithological Society’s (AOS) Checklist of North and Middle American Birds, 7th edition, 60th supplement (http://checklist.americanornithology.org/taxa). Breeding status codes are based on those used in the 2nd Ontario Breeding Bird Atlas (2001-2005) (http://www.birdsontario.org/atlas/secondatlas.jsp). The codes are:

O – Observed without evidence of breeding
M – observed only as a migrant or winter resident
X – observed during the species’ breeding season without evidence of breeding

PO – breeding possible
H – observed in suitable habitat during breeding season
M – singing male observed in suitable habitat during breeding season

P – breeding probable
P -pair observed in suitable habitat during breeding season
T – singing male observed in the same area on visits separated by at least two weeks
A – agitated behaviour
D – breeding display or intraspecies hostility
N – nest building

CO – breeding confirmed
AE – adult entering presumed nest site
DD – distraction display
NU – used nest
FS – adult carrying food or faecal sac
NE- nest with eggs
NY – nest with young
FY – flightless or dependent young

This list includes all birds observed from within the boundaries of the Koffler Scientific Reserve during the observation period. Of the 186 species and hybrids listed, 182 are considered locally native, while 4 (Rock Dove, European Starling, House Sparrow, and House Finch) are introduced. Information on any additional species (preferably with photographs) would be welcomed by the authors.

Clicking on the latin binomial of each species will bring you to GBIF occurrence records for that species.
