The Committee found that most the Ontario Bird Records Committee were of an excellent standard, (OBRC) of the Ontario Field thoroughly covering all salient points Ornithologists. A total of 172 records of the observation and often was reviewed by the Committee in meticulously detailed. There were 1992. Of these, 129 (75.0%) were fewer reports with very brief or non­ accepted, five were deferred awaiting existent descriptions.

The bird at Tiny Marsh was presumably the same individual returning for its second summer in this unlikely location. Eared Grebe (Podiceps nigricollis) North Only (O/1/1) 1992 - two adults, 29 May, and eight adults, 5, 6 June, Rainy River Sewage Lagoons IS.L.), Rainy River (Dave Elder, Don Graham; found by Rob Parsons). A most remarkable number of Eared Grebes for Ontario. Hopes that these birds might stay to breed were unfortunately dashed when the level of the lagoons was lowered drastically shortly after the second observation. American White Pelican (Pelecanus erythrorhynchos) South Only (2/23/6) 1992 - one adult, 16, 17 April, Hamilton Harbour - Hamilton- Wentworth (Rob Z. Dobos) - two, 15 May, Cook's Bay, Lake Simcoe, York (Theo Hofmann) - six adults, 15 May - 2 June, Long Point, Haldimand-Norfolk (Jon McCracken). - one adult, 21 May, Evansville, Manitoulin (Alan Worming!on) - photo on file. - one adult, 28 September, Hawk Cliff, Elgin (Barry Cherriere, Bruce Duncan, Marvin Smout). - one juvenile, 2-15 October, Frenchman's Bay, Durham and 17 October, over Whitby, Durham (Ron Pittaway; found by Ariel Shamir). 1988 - one, 12 September, Seagrave, Durham ICarol Shepherd) - photos on file. Sightings of this species in the south of the province continue to increase slowly. Great Egret (Casmerodius alba) North Only (2/3/1) 1992 - one, 9-12 August, Finlayson Lake, Rainy River (Tom Nash, Dave Elder, Don Graham) - photos on file. Snowy Egret (Egretta thula) (l/8/4) -'North Only until 1991) 1992 - one, 8 April, McLaughlin Bay Wildlife Reserve, Durham (Jim Richards) - two, first summer, 2 May, Hillman Marsh, Essex (Rob Z. Dobos). - one adult, 6 May, Long Point, Haldimand-Norfolk (Paul N. Prior). - one, 17 May, Hillman Marsh, Essex IRobert R.

Cattle Egret (Bubulcus ibis) North Only (4/8/0) 1991 - one, 29 October, Whitefish Lake, Thunder Bay (Ted Armstrong, Jean Hall-Armstrong; found by Ray Drew) - photos on file. This was another northerly stray from the Cattle Egret influx into Ontario in the fall of 1991. It was found by a trapper, and brought in to the Ministry of Natural Resources at Thunder Bay in a weak and emaciated state. It was taken to the Chip­ pewa Zoo for rehabilitation, but it did not survive. ONTARIO BIRDS AUGUST 1993 49 Figure 1: Great Egret at Finlayson Lake, Rainy River from 9-12 August 1992.

A backyard spruce tree is not where one expects to find this species! Glossy Ibis (plegadis falcinellus) (2/14/2) 1992 - three, 2, 3 May, Leslie Street Spit, Metropolitan Toronto (Martin K. McNicholl). - one adult, 7 May, Smithville S.L., Niagara (Rob Z. Dobos, Wilf Yusek; found by Jim Dowall) - photo on file. Ibis (plegadis sp. ) (3/12/0) 1991 - one adult, 20 August, Holiday Beach, Essex (Will Weber). The pressure is on Ontario birders to produce the first acceptable record of White­ faced Ibis (P. chihi). This has already resulted in much more detailed documentation of most dark ibises in the province, but some individual birds will still be seen in poor light or at too great a distance for specific identification. Greater White-fronted Goose (Anser albifrons) South Only (2/23/1) 1992 - one adult, 25, 26 March, Strathroy, Middlesex (William G. Lindley; found by Ariel McLean).

This record is the first accepted for southern Ontario as a wild bird. It arrived with and associated with the hundreds of migrant Tundra Swans (Cygnus columbianus) in the Long Point marshes.
