LouLouBelle:
it just shows that no matter how much you plan, there are perils that cannot be removed, too bad. From a watcher's point of view, there is so much investment in watching and bonding and hoping that it is difficult to accept but from weird virus's to buildings, perils exist and take their toll. I choose to celebrate all the survivors and think about the numbers that are definitely going in the right direction due to peregrine project members who do all the things that need to be done to assist the population.

The Peregrine Chick:
Just a note ...

There is usually a difference between window collisions involving adult birds and window collisions involving young birds.  Dimming/turning-off the lights, decals, window coveringes, etc will help with the former particularly during migrations, but won't do a darn to prevent collisions by most new fledglings - its not a case of "can't see the window" so much as "oops".  I'm being a bit flip, but fledglings tend to not have problems avoiding windows, but rather that they have trouble avoiding buildings and we like our buildings with lots of windows.

So if you are talking about the fledgling that died, it would be more accurate to say she hit a building, not a window.  By the dates of the posts/photos, she was inexperienced so it doesn't matter if it was concrete or glass, she was going to hit it.  It could have been an error on her part, she could have hurt herself (sprain/strain) and been unable to exhibit the fine control necessary, or she could have caught a cross-draught or gust of wind or she just could have not understood the danger the building posed.  We had one of those, bird took its first flight flew directly into a window on the Canada Post building (think that was one of the times the peregrines used the east-side roof nestbox that was removed many years ago), went into rehab for a month or more, was released from the Hotel when s/he had fully recovered and had learned how to hunt on her/his own.  Within seconds, it flew into the same window and this time killed itself on impact.  That building has lots of glass but it wasn't the glass that was the problem, in this case it was the bird.

I should note that hunting peregrines crash into all sorts of things, including the ground - experienced adult peregrines have killed themselves by stooping on a duck or somethng similar and driving them both to the ground and killing both on impact.

The window imprint made me cringe. I wish they'd left that out. Very sad but thankfully very quick.

Sue, this is the University of Calgary nest they are talking about not the U of A nest.
Our chicks are due to fledge sometime next week and my fingers are crossed.so are my toes and other things   ;D ;D

bev.:
If you saw that window the female crashed into , it was floor to ceiling glass.
I have been trying to get them to put some decals on windows like that , at least. But who am I to them.
We do have some colorful flags in some of the pedways, but not the one by the clinical science. and why you ask. Because we have the new Heart building close by.  GRRRRR

I am so worried about the glass at our site.
