I attempted to see the Gyrfalcon twice today and on my second attempt, I got lucky! A lovely adult gray morph bird. It has set up winter territory along Appleton Rd and apparently visits the large deciduous tree on the property near 4490 Appleton Rd. See pic below:
Photo: The GISS of a perched Gyrfalcon. Note the massive shoulders dwarfing the width of the head; the long, tapered body; and the very long tail. Though this feature cannot be discerned in the above pic, note that with perched Gyr’s, the wing tips fall well short of the tail tip (unlike Peregrine).
