Saturday night most people probably saw the ontbirds message about a Myiarchus flycatcher seen by Chris Burris on Hasting's Drive at Long Point. Myiarchus is of course a genus, containing a number of species that occur in North America. In Ontario, Great-crested Flycatcher is the only regularly species, a familiar breeder to 99% of all birders. If this sighting had of occurred in May or June it might have not raised any eyebrows at all. But it occurred on October 13th, and GCFLs should be long gone. In fact, the record late date for Long Point is October 10th (or perhaps this date is Ontario, I'm not sure). So, we either have a record late GCFL, or a mega has found it's way to Ontario. Ash-throated Flycatcher is the most likely vagrant, and this is why the message got posted to ontbirds, and why many birders were out searching Hasting's Drive today.
It probably goes without saying that no one refound the bird today or we would have seen an ontbirds post. Birders from afar, as well as the locals scoured Hasting's all morning/early afternoon and didn't turn the bird up. It was windy however so the bird could have hunkered down out of sight. Hasting's is definitely worth checking in the days to come - if not for the flycatcher but for the fact that this road turns up its fare share of rarities.
