10 species we have a record of for Ontario, but you aren't likely to see it again:
10... Lesser Sand Plover – formerly Mongolian Plover, could occur again – but finding several species that aren’t on the Ontario checklist would be easier.
9... Varied Bunting – secretive species, only Canadian record banded at Long Point... Good luck.
8... Whooping Crane – odds of seeing a truly wild bird aren’t great... re-introduction birds could be regular though.
7... White-collared Swift – huge south American swift. Possible again, but what a rarity!
6... Variegated Flycatcher – South American austral migrant, this is the rarest species I think anyone could ever hope to re-find in Ontario.
5... Yellow-nosed Albatross - the most recent species to appear on this list. Many of us didn't even have it on the "outlandish possibilities" list, and since it just happened, it seems even less likely to occur again anytime soon.
4... Siberian Rubythroat – one was more than enough, during the “Siberian express”. If it happens again, put your money on a different species.
3... Eurasian Jackdaw – did the only “wave” for North America come over on a boat?
2... Eurasian Blackbird – no records from Newfoundland of this euro-turd. Was the Ontario record a true vagrant?
1... Slender-billed Curlew – near-extinct or extinct European curlew species, only record for North America from 1925. Never again!
Note: I didn’t add Greater Prairie Chicken... that’s boring... So is Eskimo Curlew and Passenger Pigeon. They won’t occur. Well maybe a dumb Prairie chicken could wander into the Rainy River area. They occur 75-80km from that area in MN. But meh.
