On our way back to Portage and Winnipeg we stopped by the Brandon Tower site and found the male on the top of fhe toer and the female on the raven's nest. Sbe hopped across to the south tower and started calling in what sounded like a begging call more than a defensive or protest call. Male hopped off his perch circled a couple of times then took off. Dennis got photos of Lily (and yes it was Lily) and maybe a couple of the male before he bolted - we'd like to have enough that show facial and breast patterns so we have a hope of identfying him in the future.
And to answer the million dollar question, no there are no eggs or chicks in the raven's nest where we found Lily. Nice nest though it has been polished smooth into a beautiful bowl - next best thing to a scrape but no eggs or chicks as I said. Lily is still very brown (carrying part of her immature plumage) so I would think of this as confirmation that she is still a bit too young to breed but staying here a summer with a male/mate is a good sign for next year!!
