We think one of the couples (based on their behaviour) may have lost their eggs during bad weather or to predators.  They have been successful in the past so no reason they wouldn't be this year too.

As for why "couples".  Peregrines pair bond whether they nest or nest successfully.  That pair bond really on breaks down when one of them doesn't return or if they haven't been successful and a better offer presents itself.  Ivy who was Princess' former mate had a mate before her but they couldn't manage to find a nestsite that worked and their pairing broke apart.  One of the pairs we have this year have been together for at least 2 if not 3 years but yet we haven't been able to catch them with chicks (now watch, now that I've said that we'll find they do this year!!).  So what makes a couple rather than just a couple of birds hanging out together - they spend the summer together, the go through all the courtship, pair-bonding and pre/post-nesting rituals.  Birds that just want company for awhile behave very differently.

And yes, they are here in Manitoba.

Over 300 chicks since the program began in 1981 - most are wild-hatched, but the early birds were hacked-released captive-bred birds like all the recovery projects in North America.  And tracking is a misleading word, if some reports one of our peregrines dead or injured or sighted or nesting, then we have have some tracking on the bird, if not, we know nothing.  Of all the birds that come through our project we probably know something (dead, injured, alive at one time) on about half.  Remember statistically 5-7 out of every 10 chicks dies in the first 12 months so many of these records are deaths.  A few birds had satellite transmitters put on them and the first mortality rates were the same - we know of only 5 birds - 1 captive-bred and 4 wild-hatched that survived the first year. Could be a couple more however, transmitters are notorious for dying after a short while.

They turned up, three of them - Sundance (Logan), Bristol (West Winnipeg) and Kelly (McKenzie Seeds).  Sundance spent last summer with Kelly but they didn't nest.  This year his allegiance shifted to Bristol despite Kelly's presence for a short time.  Again, no nest.  Bristol maybe just a bit young so we will keep an eye out for their return next year.
