I should have mentioned that in the bird s= een by Dorothy=2C the Keneficks and myself the wings were more broad-based = then one would expect or see in a peregrine falcon. This gives the bird a = chunky appearance. Also the tail was somewhat broader than that of a pereg= rine. With seeing a dark phase pergrine there of the Labrador race I am st= ill convinced that the bird we had was indeed a gyr and not a large peregri= ne. We did see a large peregrine earlier in the day=2C which I ruled out a= s a gyr=2C but that was an entirely different bird. I'm not sure how many = peregrines were actually on the island as I saw two at once at North Light.= Prior to that I had seen another and I spotted one which lit out over the= ocean. During the day we had spotted peregrines off and on at different l= ocations on the island=2C so conceivably there could have been four or five= separate peregrines about. In seeing the peregrines so often we had ample= study time and the bird we saw at Pond Cove stuck out as definably differe= nt from a peregrine. I'm sorry considering the weather that I did not atte= mpt to get a photo of the bird. I was so taken with the bird and in having= such a close look=2C with ample time to study it and I was trying to make = sure that we made a correct id and did not err that I did not even think ab= out my camera. =20 Sincerely=2C =20 James =20 > Date: Tue=2C 30 Sep 2008 12:28:19 -0300> From: iamclar@DAL.CA> To: nature= ns@chebucto.ns.ca> Subject: [NatureNS] Tail length in Gyrfalcon and Peregri= ne> > Hi All:> > I thought I'd add my two cents worth=2C without judging si= ghtings by others.> > I have always found it odd that David Sibley should s= tate Gyrfalcon is> "relatively long-tailed."
