The toe feathers are the longest known of any owl, averaging at 33.3 mm (1.31 in), against the great horned owl which has the 2nd longest toe feathers at a mean of 13 mm (0.51 in) [7] [43] Occasionally, snowy owls may show a faint blackish edge to the eyes and have a dark gray cere, though this is often not visible from the feather coverage ...

[2] Because of their nocturnal habits, they tend not to exhibit sexual dimorphism in their plumage. Specialized feathers and wing shape suppress the noise produced by flying, both taking off, flapping and ...
