The Schumacher report establishes the first record for northern Ontario. Coincidentally, two American White Pelicans (P. erythrorhynchos) were also present at this site at the same time. The 1994 OBRC annual report lists four separate occurrences of an adult Brown Pelican in 1994, although the possibility of these reports pertaining to a single bird is discussed (Pittaway 1995). An update to one of those occurrences based on recent evidence reviewed by the Committee, is provided later in this report under the "Updates/ Corrections" section. The two occurrences listed above fit into a pattern with the other occurrences resulting in no overlap of dates for those records. Additional sightings of Brown Pelican in Ontario during the summer of ONTARIO BIRDS AUGUST 1996 53 Figurel: Brown Pelican at Devil Lake, Frontenac from 15 to 18 July 1994. Photo by Peter Griffin. 1994 which have not yet been documented for the OBRC are mentioned by Ridout (1994). Also, an adult bird was present at Point Mouillee State Game Area, Michigan, at the west end ofLake Erie on 5-11 June 1994 (Chu 1995), which again fits nicely into this pattern. Given that this large, conspicuous species is capable of covering large distances in a short time, a single bird is presumed to have been responsible for all ofthese sightings, and no evidence has come forward to suggest otherwise. Therefore, although the occurrences in 1994 will be listed separately for convenience of reporting, the Committee will consider these to pertain to a single bird, and thus there is only one accepted record ofBrown Pelican for Ontario up to this date. TheCommittee would appreciate any further documentationon additional sightings to help clarify the picture. Known sightings in 1994 for which documentation has not been received include thoseat Hamilton Harbour (Hamilton Wentworth), Grand Bend (LambtonIHuron) , Kamaniskeg Lake (Hastings) and Sharbot Lake (Frontenac).
