Arctic Snowy Owl Prey Delivery by Male
9 July 2014
A pile of four owlets await their mother’s arrival on the tundra outside Barrow, Alaska. Soon after she alights, the male owl flies in to deliver a lemming, exchanges it with the female, and departs while she begins to provision the owlets.
From the Cornell Lab of Ornithology in the USA:
Watch Snowy Owlets in Alaska
In the tundra around Barrow, Alaska, Snowy Owls nest in the 24-hour sunlight. Now you can watch one of these nests, featuring seven growing owlets, live on our Bird Cams. The camera is located a respectful distance from the nest, so be aware that the owlets are not always visible (they tend to hunker behind a low rise). But their parents visit regularly with meals of lemming and duck—as you can see in this video highlight. What are the owlets up to now? Check in on the Snowy Owl cam.
