Yep. Looks like Skye may be another two-timer like his dad and his brother.
I was just looking at distance between sites. If the Quest is at Harlequin on Duncan Mill Rd, North York, ON, looks to be over an hour drive time, 70+ miles between sites, so I don't think he is a two-timer.
I may have the wrong location for Quest, so I'm sure someone who is more familiar with the area can confirm.
So, now I wonder what happened to Rosie?
You are correct. Brantford is on the west side of Hamilton/Kitchener/Waterloo where Quest is on the east side of Toronto. I don't see that there was a nest found, so he could have just been passing through in the spring. We shall see...
