The species are presented with ecology, moulting patterns as well as the feathers’ size, shape and color differences. Differences in anatomy (skull, etc.) in the end of the book. The author also presents relationships between feather morphology, behaviour and ecology of this group of birds. A very unique book for the identification of owls, perfect for both feather-enthusiasts, birdwatchers and ringers.
