Non-Resident Sightings - 2020
Cammie:
Thanks TPC. I appreciate the info.
birdcamfan:
Great questions. Thanks for the ever informative explanations.
The Peregrine Chick:
Sorry BCBird, the "good" was in reference to overwintering, don't know if they are particularly good or not in locations other than Scotland/Spain where they evolved ... :-\
bcbird:
Madame had Spanish & Scots subspecies in her genetic grabbag...however...none of those really good genes were passed along to her kids...
TPC, why are Scots and Spanish subspecies genes especially good?
The Peregrine Chick:

I wish there was a typical date ... but there really isn't. Depends on the bird, the pair, the location, the weather, what else is migrating and when, etc.

Madame is to our knowledge the only one of "our" birds that overwintered. I should say that she originated in Cedar Rapids, Iowa but turned up here the following year (1990) and was last seen in the West Winnipeg territory in 2005, the year after Princess took over the Radisson territory.

Food. All the good stuff heads south. Alternative is Kraft-Dinner-with-Wings for 6 months. Wouldn't you leave? Seriously, our subspecies (anatum) is hardwired to migrate though some in recent years haven't - but whether that is because they have some non-migrating subspecies genes in their makeup, I couldn't say. Madame had Spanish & Scots subspecies in her genetic grab-bag, neither of which migrate but whether that's what made her stay here all alone, I have no idea. I would appear however that none of those really good genes were passed along to her kids however as none of them seem to want to hang around downtown past about early November ...
