Original observer: Fred Prowse. First record for Muskoka. Source: Percy Taverner Ornithological Notes; James Fleming. 1901. List of the Birds of the Districts of Parry Sound and Muskoka. Alex Mills. 1981. A Cottager's Guide to the Birds of Muskoka and Parry Sound; Greg Rand pers. comm. 2017. According to Percy Taverner's Ornithological Notes, this bird was originally in the "possession of Mr. Edward Prowse Prop[rietor] of Beaumaris Hotel Muskoka Lake Ont. The bird was killed there in the yard with the chickens one morning after a severe storm. The exact date is lost but it must have been 1888 or before." This eBird record has been entered as 15 May 1888. Fleming (1901) stated that the bird was at the Beaumaris Hotel, and, according to Mills (1981), stood there for a number of years. Greg Rand, Assistant Collection Manager, Canadian Museum of Nature, stated that the specimen was acquired by the Canadian Museum of Nature in 1917, specimen #11443. The collection tag attached to the specimen indicates that it was collected "before 1900" and gives the collector's name as "Fred Prowse". A note with the acquisition in the CMN accession catalogue states: "1 Mtd. Crane killed in barnyard with poultry about 18__." A note pasted into Percy Taverner's Ornithological Notes entry for this species is titled "Measurements Sand Hill Crane Beaumaris Ont." and provides the following information regarding the specimen: "culmen 3.8, bill to feathers 4.9, wing 15.8, tarsus 6.06, middle toe claw 3.0, tail 5.55, height of bill .95, length estimated 36.0." In the early 1900’s, the Sandhill Crane was a rare sight in Ontario, but since then its numbers have grown and its range has expanded in the province. This species, however, may have once been a regular migrant through this area and southern Ontario prior to the 1800’s. According to Devitt (1967), Sandhill Cranes were well known to the Huron Indians in what is now Simcoe County. Gabriel Sagard, a Christian missionary who lived in a Huron village on the southern shore of Lake Huron from 1615 to 1624, noted in his account on New France and the Huron people published in 1632, that “in the seasons all the fields are covered with cranes or ‘Tochingo’, which come to eat the corn at seed-time and when it is ready to harvest.” Archaeological work undertaken in nearby Coldwater in 1946 uncovered four bones identified as belonging to this species (Devitt 1967). Lumsden (1971) suggested that these birds were likely from the Hudson Bay Lowland population that wintered in New England, but in the 19th century this population was extirpated. Lumsden (1987) later stated that birds from farther west in the Lowland recolonized this vacant breeding area, but did not follow the same migration route as the previous occupants, thus accounting for the paucity of southern Ontario records during the first half of the 20th century. Beginning in the early 1950’s, however, numbers in the province began increasing, with birds observed in the Algoma District north of Sault Ste. Marie. By the late 1970’s, possibly augmented by colonizers from a surviving population in the upper Michigan peninsula, a breeding population of over 200 cranes was present in the southern Algoma District, and by 1985, birds had colonized Manitoulin Island and the Bruce Peninsula. In 1982, only the second record of this species in Muskoka was documented when Lex Calacott observed six birds on a small lake near Huntsville on 9 October (Bowles Journal; Ron Weir. 1983. Ontario Region Autumn Migration Report. American Birds 37(2): 75).
