This video from the USA says about itself:
First Glimpse of Barred Owl Chick #1
On April 9, 2014, the female Barred Owl on the Wild Birds Unlimited camera left the nest for a few minutes and we were able to get a glimpse of the hatchling #1. Note the fish prey in the bottom right that was brought into the nestbox; not always a food associated with owls.
From the Cornell Lab of Ornithology in the USA:
Nonstop Owl Action
Our two owl cams have been a whirlwind of activity over the last few days. The three owlets at the Wild Birds Unlimited Barred Owl Cam were named Wynken, Blynken, and Nod by the cams community, and on May 12, Wynken fledged from the box to a nearby maple. Over the next couple days the other two owlets will leave the box, and may not return to it ever again. Don’t miss your chance to see them before they depart for the outside world! Watch the owlets.
In addition to the fledging activity, two of the five eggs at the Texas Barn Owl Box hatched out over Mother’s Day weekend (watch the highlight video), and the third hatched yesterday! The last two should hatch over the next few days. Watch now.
