Stefansson O. 1997. Nordanskogens vagabond. Lappugglan (Strix nebulosa lapponica), Boden.
There are short summaries in English to each chapter in the book.
In the book are my earlier reports before 1996 on Great Grey Owl in Sweden listed.
I have maked four supplements to the book: Supplement No 1 (1997-2000), Supplement No 2 (2001-2004), Supplement No 3 (2005-2008) and Supplement No 4 (2009-2012). The reports are only made as articles on a CD and are not publiched as articles in magazines or books. All are continuations to " the book of the Lapland Owl" and have short summaries in English. The supplements/CD can only be ordered from me.
