Bob,

Good post. From my experience and in conversations with some of the top
Snowy Owl researchers in the country, Snowy Owl are most active in the
normal nighttime hours, whether it is light or not (theoretical night),
although it can vary depending upon what they are feeding upon. Owls
feeding upon rats and other nocturnal prey are more strictly nocturnal
while those feeding upon seabirds are more flexible. No matter the prey
the are usually only active during the middle of the day when dislodged by
disturbance from other birds or people.
