I saw one falcon yesterday hanging out in the cubby hole on the north side.  :)

--- Quote from: burdi on July 10, 2012, 22:41 ---Thank you for the info, TPC!  It did appear more like a drainage of some sort, but after zooming in still wasn't sure. Still wondering if it is just a water drain or what, just in case they bite into it.
 
Sorry I don't quite understand, but what is the concern there when a parent leaves the eggs? Could you possibly mean predators in the area, or is it that the eggs need some stones or a higher edge perhaps?

Also, IF you do want them to nest there, wouldn't you want to prepare the opening with a stone base before they return next year, so they can make a scrape.

The adults have their feet under the eggs and on a flat surface when they pull their feet out from under, the eggs roll into the sides, back or off the edge.  That is one of the reasons they build bowl-shaped scrapes in whatever material is on their chosen ledge.  We are looking at a modified tray that would let us add gravel and have drainage and still be big enough for the peregrines to get in and out of and for up to 4 growing chicks.  We have ideas that we hope to flesh out in the next couple of months so that we can have something in place before next spring.

That is so exciting to hear, TPC.  Another nest in Manitoba would be marvelous!   :D

The “opening in the wall that cables are coming out” reminded me of a similar size opening in a wall which is successfully occupied by the Niagara Falls falcons.  ;)

Do you happen to know what kind of cable is running through this opening? I find it difficult to tell from a pic, especially without being able to see what the cable actually leads to. Perhaps electrical, or possibly a drain of some kind?  Just curious if this cable may cause any problems should they decide to nest there.  ???

Its not a cable it's a drainage tube.  As for problems, the opening as it is is more of a problem, there is now protection for the eggs when an adult "leaves".  We've already thought of ways we can upgrade it a bit if they are interested again next year.
