Frank is the person I was paired with during the fledge watch here in Etobicoke, really nice guy and extremely knowledgeable about birds. I was supposed to go down this weekend to help him with the migration watch but we are rained out so I didn't go..hopefully next weekend!

Wow Carly, this sounds great. Please let us know what happens next weekend. :)

I have been checking in on the Ospreys being tracked by the Highland Wildlife Foundation from Scotland and it is fascinating to follow the migration route in detail. The technology is pretty impressive. Solar powered transmitters provide hourly, accurate GPS, as well as readings of direction, speed and altitude. This is combined with, I think they said, Google Earth Plus. Of course, there is a downside, as there are not always happy endings, especially for the juveniles.

Does Alberta report on the birds that they have been tracking?

There are a few birds that have transmitters on them, most, if not all, from Alberta. If you want to find out how difficult it is to actually get a transmitter on a peregrine, check out the Edmonton, Alberta thread - they tried to catch Radisson, the female in Edmonton this year, to put a transmitter on her and she was having none of it! Tried a couple of times as I recall. They (Alberta & CWS) do track these peregrines' migration but they don't have a website or GIS tracking for them.
As for hawkwatches (as they are frequently called) they happen at all key raptor migration routes across the country - we have a couple of locations in the Pembina Valley where the elevation and topography makes for the perfect route for raptors and for folks to watch them - the latter because the route causes the birds to travel along a narrow flyway and the result is you can count hundreds of birds at a sitting. Local birders that stake out these locations usually email their sightings so if y'all are interested, I'll post raptor sightings as I receive them as I'm on the list. I'll start a new thread tonight and post as they come in. I'm not sure if there is a blog similar to Frank's for Manitoba, but I'll have a look around ...

Does Alberta report on the birds that they have been tracking?
The Peregrine Chick:
Usually the chicks leave first in my experience, the adults stay later. Interestingly enough, except for Madame who used to overwinter here, the bird that remained latest was the one that hatched on the building. Now in the Radisson case, that's always been the males, but as I recall Burnsie was a female of ours who came back to nest and she was the last one at a nestsite she had with an unbanded male ...
When do I expect them to leave?
Short answer: as long as the weather remains good, they don't "have" to leave.
Longer answer: The weather is good, the eating is good (it keeps flying by) so we could see them into October if the weather stays like this. They will follow the prey, then leap frog them further south. Peregrines can take a week to fly from Mexico to Wood Buffalo in northern Alberta but that I think is pretty quick. I do know that one of the U of M chicks (one of T-Rex's) was last spotted in Winnipeg a month before it was spotted on a beach in Veracruz Mexico. How reliable is that sighting? The chick was observed by participants at an international peregrine falcon recovery meeting. They sent us a postcard with the bird's location circled on the photo of the beach. Cracked me up actually.
The geese are moving but I don't know if they are staging here as the eating is good or if they are actually making concerted efforts to head south. I found a real-time GIS mapping software on a hunting website, but so far no one has submitted any information on the migration yet - could have something to do with hunting season start dates which I don't know about, or something. Its a new find, but I'm going to keep an eye on it as it looks pretty cool .... from what I read/see, its suppose to update every 15 minutes, so as long as folks submit data, the map should change frequently. You also have a choice of things to look at i.e., all waterfowl, dark geese, light geese (I assume that's feather colour), puddle ducks, divers and teal.
Here's the link if you want to keep an eye on it too: Waterfowler.com's National Migration Mapping
