Someone (mostly Cirrus) never leaves the corner of the nest box and Mackenzie spends quite a bit of time inside the box.  Hmm, is he checking on eggs or is he working on the scrape?  However, they are definitely not finished producing eggs as they are still mating and hard incubation has not begun.

When Bill arrived at the bridge this morning around 10:30 AM he found an adult in the Hamilton Hydro Tower.  It was alarm calling and made several rushed trips towards the Skyway Bridge.  We have no idea what was so upsetting as it was out of sight.  When the danger had passed, the adult came back to the corner of the nest box and it turned out to be Cirrus.  When she landed on the box, Mackenzie exited the box where he had been the whole time.  He flew around the bridge and came back and copulated with her.






Mackenzie Leaves the Nest Box

While we watched this afternoon, we heard lots of calling and saw Mackenzie deliver a meal to the roof of the Burlington Tower.  He prepared it a little as we saw lots of black feathers flying.  He then delivered it to Cirrus in the next box with great vocals.  Cirrus didn't appear too interested so he removed it and took it to one of the picnic tables.  He then took off under the Skyway and appeared to stash it up on to one of the Skyway light standards.  He returned to the Hamilton Hydro Tower where he watched Cirrus.  A short time later, he circled the bridge and copulated with Cirrus again.
