I just saw this posted on Ontbirds by Alan Wormington...
Apparent **KELP GULL** at Wheatley Harbour
Yes, you read that right! Read the whole email here. I haven`t seen the photos yet but apparently they are good for it being a Kelp Gull! This would obviously be a first for Ontario! The first North American record was from 1989 in Louisiana, where it was eventually found to be breeding. I am not sure if there are any records closer to Ontario than the Louisiana ones.
Great find by Alan! He saw it on Friday, took some photos, and saw it again on Sunday on the rocks at Wheatley harbour. Lots of photos taken apparently.
I am in Nova Scotia still and flying back Tuesday evening. If all goes well I know where I will be Wednesday morning.
