Just trying to get caught up on the history here, am i correct to assume that in previous years Trey was paired with his mother?
Who comes back first each year? Do they fly away together and come back together or do they just hang around and wait to see who they are mating with this year?
No, I don't believe Trey ever paired with his mom. Trey was hatched at the Radisson in 1996, and his mate, Radisson, who he has been together with for some time, is a wild hatch from 2002 from Minneapolis, Minnesota, USA.
Either one can come back first; they do not leave together, and they do not return together. But, Trey and Princess did arrive back about 3 days apart this year, I believe. And here in Edmonton, Radisson and her mate, Damon, who we believe is the same as last year, arrived back about 2 days apart, if I recall correctly. All falcons have a really long flight to and from South America, but they can fly as much as 600 miles in a day.
