I found one Gyrfalcon on a electricity pole on a gravel road which forks of Rannie Road. It flew away and landed on a big electricity pole. It sure is a beautiful bird! I am not sure if it the same one, probably. I could not find the Prairie Falcon.
There was also around 90 Tree Swallows (2 Violet Greens) on this same road.
