Name the flora AND the fauna. For extra points guess the age of each... There are many clues in the photos, including the texture and color of the bark, branches, seeds, and leafs. There is even evidence of insect damage and bark problems. The mother owl was first seen and photographed on the nest this year on January 19th. The owlets were first spotted on March 5th. The photo of the owlets was taken March 22, 2007.
Owl chicks, then? Perhaphs 3 weeks old. Can't be more specific - I am not good with birds, but just a guess: Strix aluco (Tawny Owl?)
