Manitoba Peregrines > U of Alberta, Edmonton, Alberta
U of Alberta - 2009 / Damon & Radisson
The Peregrine Chick:
Peregrine return times are variable but usually within a range. Its all weather and prey based. In cities the birds can eat pigeons and other overwintering birds but cliff-nesting birds need to be sure that there are prey species available for them.
The Radisson birds are back earlier than usual, I'm of the believe that these two were in a position to surf the leading edge of the snow storms we have had (and had and had and its still snowing now) recently. Had they been on the other side of the storm, they would be cooling their jets south of here. We have seen this with Alberta peregrines with transmitters on them. One year a bird sat for 10-12 days in Denver waiting for the weather to shift ... And besides, our birds appear to have not done much since they returned so we may still get eggs at the usual time even though they are back early. We will have to see.
As for Radisson and the rest of the Alberta cohort, they will probably kite in in the next few days and then the fun will begin. Keep in mind, its really only the beginning of April and the start of peregrine returns to Canada (excluding the overwintering birds). And I haven't seen more than a few peregrines at a time on the HawkWatch migration stats so I have to hope that more will show soon ....
The Peregrine Chick:
Did a little housekeeping on the Dutch "raven invasion" as they were causing some confusion re: sightings, species, etc. They are now in a separate thread in the Netherlands board ...
bev.:
It is not until this time that the peregrines here return. the female was sighted last year around April3. So any day now. We are expecting snow tonight so....
by the way the note I had on the crows was not from the biologists I deal with, it was from another biologist . In any event, the raven made a quick appearance just now, but we will wait and see.
I do not wish these ravens any harm or the peregrines. I guess that is one reason why i am concerned. I may come across as a non lover of Ravens. that is not so, I just do not like them in my small area . they are very intelligent and if you ever see their eyes, they are so bright and they have the shiniest black coat.
So today is another day at the soaps of Edmonton. the Manitoba falcons came a bit later last year , so she may appear later this year.
I do not know if I mentioned that the transmitter female was still in Columbia as of End of March. she does not make her move home until about now. ??????
Have a great day everyone :) :)

The Edmonton Falcons are expected home in the next few days. From what I read on the website and from what Bev has said, they usually arrive home between April 3rd to April 10th - not exact dates but in that range. So possibly today or this weekend, one or two may show up. Really depends on the weather patterns and whether or not other species they rely on have started the migration northwards I think.

Goodmorning folks! 8) Putting my sunglasses on in good faith that "WE WILL HAVE SUNSHINE!" We'll have to go somewhere to follow the Netherlands nest together as that has become fascinating if not worrisome. I'm not happy about the prospect of a battle at the Edmonton nest and hope that if there is one I miss it. I'm at the point where I hope the peregrines have found a place to nest that they prefer over this site. Where are they anyway, were they expected back by now?
