Tower Nest - 2013 / ? & ?
Kinderchick:
Very, very interesting discussion between you two, TPC & RCF. :) Lots to think about, both from the bird's perspective and the Recovery Project's perspective.

They wouldn't be able to see much from that location if it is sitting on a roof floor. It was my understanding that the falcons like to see what is going on outside as far as they could see. It seems to me that they prefer this north location better.....they can see for miles in three directions. :)

Actually the roof nestbox is close to the edge of the roof its just hard to see and it's at about the same height as the catwalk on the towers. They've been making scrapes in the box both this year and last, so it is of some interest. And its higher, got more view than the West Winnipeg site and we can't nuke those birds off there! :o
Technically, every site is different. We know the birds like the catwalks on the towers at this site, but we can't access the catwalks but we can access the roof, so from a project perspective, if we can get the birds interested in a rooftop nestbox that would be a good thing. So the nestbox is within site of the catwalks, about the same height and in a safe location. If they did/do nest on the catwalks, the box is also close enough that if we had to/wanted to move them for safety's sake (remember the last chicks were predated from the catwalk) then we could and the parents wouldn't have any problem making the move.
As for the cubby, it is a decent location though a bit small for growing chicks and it could be a very messy nestsite but hopefully our box design will help reduce that and the risk of bacterial/fungal infections from one year to the next. On the downside the cubby faces north so it is very exposed to bad weather (wind and rain). Wild peregrine nests tend not to be north-facing and in fact recovery project nest siting guidelines were to avoid north facing boxes/sites. However, if that is where they want to nest, we will work to find a way to keep them, their chicks and their nest safe.

It is still bare floor. What can't be seen from your photo is that there is a second half to that cubby behind the back wall that is visible. In order to be able to access the box and the chicks safely, we've had to custom design a box that fits, is accessible, transportable and which is 4-season - the inside of the cubby opens into the building so it has to be winter-proof. Once we are sure they are actually nesting there we can get either a temporary box under them or the final box around them without the parents abandoning the eggs.
I should say that if they haven't started laying, an earlier report from the site had them interested in the ravens' nest and apparently they have been in the nestbox on the roof as well. Hopefully they will choose a site soon and we will know whether we need/can get a box under/around them.
Looking forward to your next photos ... :)
