The Peregrine Chick:
The first of the falcons appeared on the hawk migration site HawkCount.  It was an American Kestrel today at the Beamer Conservation Area in Grimsby, Ontario.  How it managed to get all the way up there without being seen anywhere along the way is interesting.  We will have to see if it really is the first of the returning birds or an overwintering bird in the right place at the right time to be counted.

According to the reports from these migration sites, there are some birds moving but not many so it looks like it is only just starting.  Looking at last year's numbers for March 1st, the birds are (so far) moving slower than last year.

The Peregrine Chick:
Just a note, I've merged the 2012 and 2013 thread here so folks can go back if they wish to see what happened last year ... thought it might be useful for comparison's sake ...

The Peregrine Chick:
First raptor migration report just turned up on the HawkCount website

Borrego Valley, California - 22 turkey vultures on Feb 7th

And that is the start of the wave ... though apparently there are birds in downtown Topeka (Manitoba grand or great-grandkids) and a bird spotted at the nestbox in Lincoln, Nebraska (possibly Alley?)

Sorry Alli, I answered about trained observers but not about the unknown raptors in your post. 

As you have undoubtedly surmised, since I know you are fan of the HawkCount site, "unknown falcon" just means they couldn't identify species but they were able to identify family/genus.  Usually because of distance between viewer and bird, or it could be weather or lighting conditions or even the number of birds bombing through an area (the Ancon Hill site in Panama is a good example).  The most commonly used "unknown" is "unknown raptor".  So far there have been 4 unknown falcons this spring but thousands of unknown raptors reported.
