Radisson - 2013 / Ivy & Princess
The Peregrine Chick:
The Radisson chicks look like they've just crawled through a mine field ...
The Peregrine Chick:
It's not the height of the building they are leaping from it's the height of all the other buildings around them that can be problematic. We have had birds nest much closer to the ground with nary a problem because all the buildings around are pretty much the same with the odd building or structure being higher. In Brandon, McKenzie Seeds despite being much lower than the Radisson and lower even than the Radisson ledge is surrounded by lower buildings with the exception of the Scotia Bank building to the west. In downtown Winnipeg, the only lower buildings are immediately across from the nestledge - getting from there to the much higher buildings has proved to be the problem. And that is assuming the birds land close to the Radisson, the last few years, fledges from the west side have gone at least two blocks before going down, 2 blocks east from the Radisson is Portage & Main. Unlike lower buildings or to a lesser degree, the tall buildings in downtown Winnipeg modify the wind patterns so winds are often stronger downtown than they are elsewhere in the City which for a young bird who has no idea how to fly is a problem. We used to have a nestbox on the roof on the east side of the building but because of the number of fatalities and injuries during fledges, we removed that box. The nest ledge has been used more often but it too has a similar record.
east side box
* 1990-1992 - I think was used once but don't know for sure what year or what the outcomes were ...
* 1994 - Madame & Pop - 3 chicks, 1 foster chick - 1 crashed in to the Richardson Building, another into the Trizec Building, 3rd died of a toe injury in the nestbox
* 1995 - east side box removed
east side ledge
* 1996 - Madame & T-Rex - 3 eggs; 1 chick known to have survived, other 2 have never seen/found/reported after they fledged (pre-cameras)
* 2000 - Madame & Trey - 2 eggs, 1 egg didn't hatch; 1 chick died of exposure
* 2006 - Princess & Trey - 4 eggs, 1 egg didn't hatch; 1 chick died immediately after fledging, 1 injured after fledging but recovered and was re-released from the nestbox - no further problems, 3rd chick was not observed/found after fledging but is known to be alive
* 2008 - Princess & Trey - 4 eggs, 1 egg didn't hatch; 3 chicks died of exposure
* 2009 - Princess & Trey - 4 eggs, 1 egg didn't hatch, 1 chick injured but recovered & was re-released from the nestbox - no further problems, 1 of the other 2 came very close to crashing a couple of times but was a very clever bird! - 1 of these birds is known to be alive, 1 we know has died
* 2013 - Princess & Ivy - 4 eggs, 1 egg did not hatch, 1 chick died of exposure, the surviving 2 we hope will do better fledging higher up

--- Quote from: newchick on June 19, 2013, 15:41 ---Rose, I think height might be an issue. They are currently only 13 stories high up, and most buildings surrounding the area are higher, and if they need to do short flights from one building to the next, I think height might be and advantage. And thinking as a glider pilot, the thermals, (warm air lift) and updrafts for picking up a fledging bird might be better at the higher height.

Just a little info here, the McKenzie chicks have fledged from a 9 story nest box to 4 and 5 story buildings with great success for the last 20 years and the last 2 years they had to fledge from 2 stories lower. The next day they can be found on the MTs tower and even on the Scotia towers which is 13 stories, they seem to manage this with no difficulty.

Looks like our Radisson babies are starting to change to more adult plumage. I see a lot of darker grey coming under that white fuzz. :o
