Observation details

First record for Muskoka. Collector unknown. Fleming (1901) did not record this species on his List of the Birds of the Districts of Parry Sound and Muskoka, and the earliest record for Muskoka, documented by a specimen, is a juvenile female bird, taken by an unknown collector working out of the Go Home Bay Biological Station, on 13 September 1902 at Go Home Bay, Georgian Bay. It is now in the collection of the ROM, catalogue number #02102312. The Sanderling is a more common and abundant migrant in the fall than in the spring in Ontario (Sandilands 2010). Failed breeders begin heading south by late June, with the main adult migration period occurring in southern Ontario from mid-July to mid-August (Pittaway 2010; O’Brien et al. 2006). Juveniles depart the breeding grounds early- to mid-August and arrive in southern Canada mid- to late-August, with peak passage mid-September to October (O’Brien et al. 2006; Pittaway 2010). It is likely that most of our fall records, like this one, which have occurred late-August to late-September, are of juvenile birds.
