Eurasian Pygmy Owl`s nestling (Glaucidium passerinum). 31.5.2007, Tornio.
To show how small they are I lifted him/her on my finger after ringing it. Now about 15 days of age...it`ll leave nest at the age of one month.
This one weights 50 gram - almost as much as fullgrown male of Pygmy Owl. They eat a lot when at nest, but lose weight when starting to fly
