!!! Update & Incubation Behaviour!
March 25, 2012 - Etobicoke - Sun Life Centre
Kathy Reports:
Last Friday, March 16th some of the CPF staff were out at the site to do an ‘egg’ check and at that time nothing was found. This past Monday when I arrived at the site I couldn’t see any falcons around so I thought perhaps no one was home. A few minutes later someone stepped onto the roof of the building and suddenly Angel flew out of the box alarming and crying. She landed on the centre tower where she continued to cry out in distress. I noticed how puffy she was and how bottom heavy, I was amazed she actually flew that far as she was obviously ready to lay an egg. Fortunately whoever was on the roof vacated quickly and she flew right back to the nest box.
From Monday to Friday, she was either in the nest box sitting, laying down or standing by the nest box any time I was able to check on her. Today I was able to spend a few hours on site observing. When I arrived I literally saw Angel fly up to the ledge from the south and she entered the nest box. As no one immediately exited, I thought okay well she’s not incubating yet then as she wouldn’t leave the eggs on their own like that.
I could see a little head peeping over the lip of the nest box and right next to it a falcons tail..hmm I thought, either she’s a pretzel or there are 2 falcons in that box! Sure enough a few minutes later Jack exited the box and stood on the ledge watching over the condos. A few seconds later, I saw several people on the rooftops and all heck broke loose. Jack started alarming, at first not too loudly but then more rapidly and loudly which brought Angel back out of the nest box and she took to the skies and started circling above the people on the rooftop. Jack went back into the nest box and watched as I could his little head peeping out.
After about 15 minutes of this, the rooftop was cleared and Angel returned to the nest box and Jack exited. I could Angel arranging herself and then she was flat out in the nest box where she stayed for next few hours. Jack left for his other site and then came back and stood on the camera for a good 45 minutes before I left. During that time I didn’t see Angel leave the nest box nor could I see her tail feathers or her head..the question is how many eggs? It was a warm day today here with a high of 17c so no reason to keep the eggs warm if there were only 2 and there were would be more mating until all the eggs were laid and I saw no evidence of any of that today. It looked more like incubation behavior to me.
Temperatures are expected to plummet the next 2 days so regardless of how many eggs, they will be on them as it’s expected to go below zero in the evenings and only a high of 4c.
