The revisers are grateful to David Parmelee for writing the first Snowy Owl BNA account (# 19), in 1992. We built upon that foundation for this new and updated edition. We are especially grateful to the researchers, past and present, who have dedicated many years of their lives studying Snowy Owls, in North America and Europe.

Many other researchers have not published results of their studies but maintain large and significant data sets, collected over many years in the field. We are especially grateful to them for sharing their unpublished results and their great knowledge of Snowy Owls. These people include: Bud Anderson, Mike Blom, Tom McDonald, Hardy Pletz, Marten Stoffel, and Dan Zazelenchuk. We also want to acknowledge the research by Irina Menyushina, whose 27 years of Snowy Owl breeding season research on Wrangel I., Russia, is the longest running breeding study in the world.

DWH is especially grateful to the Inũpiat people of Barrow, AK for allowing him to research Snowy Owls on their native lands for the past 22 years.
