A very young owlet (estimated to be around 10 to 14 days old!) hangs with its mother at Metzger Farm Open Space in Westminster, Colorado. The photographer notes: "Given the mother owl's behavior in the previous photo, there are likely other younger owlets in the nest."
For more pictures of the owls (this is the only shot so far of any young 'uns), check out this photostream.
