History
The Ontario Nest Records Scheme (ONRS) is a joint project of the Royal Ontario Museum, Bird Studies Canada, and the Canadian Wildlife Service, established in 1956 to track the health of Ontario’s bird populations, by collecting information on nesting success and distribution.
Information on birds’ nests is collected by volunteers and professional researchers, using cards distributed by the ONRS. The information is then entered into a database and used to monitor clutch size, hatching and fledging success, predation rates, and other factors, to determine whether sufficient young are being produced to maintain healthy populations.
The information is also used to provide information on egg laying dates to help identify safe periods for management activities such as harvesting hay or timber, document the effects of climate change on breeding birds, evaluate the impact of predators on nesting success of songbirds, document basic breeding biology such as nesting habitat, nest site selection, incubation period, renesting, additional broods, etc., and to document the breeding distribution of each bird species in Ontario.
