Arctic Warbler (Phylloscopus borealis) Science Article 1
abstract
Three of these little-known Willow Warblers were taken in the southern part of Okinawa Shims, Riu KM Islands, in the fall of 1945. Unfortunately, two were lost subsequently, but in view of the bird’s rarity, it seems worth while to place on record the notes that were made on them in the field
