Introduction

The 2016 survey was the 17th year in which a detailed study had been made of the Ring Ouzel Turdus torquatus (RZ) population in the North York Moors National Park. The findings of these studies were submitted to various bodies including the North York Moors National Park Authority, the RSPB Ring Ouzel Study Group, Natural England (York office) and the land-owners and head keepers of Spaunton and Rosedale estates.

The 2016 season marked 15 years of unbroken study in the Rosedale area, only the foot and mouth outbreak in 2001 and the subsequent closure of the moors prevented continuous study since the start of the project in 1999. As in previous years the 2016 survey concentrated mainly on the Rosedale area of the North York Moors, an area of around 25 square kilometres. As in previous years, visits were made during late summer to locate Ring Ouzels prior to migration.

Finally, the north-west and east side of Rosedale was covered by Vic Fairbrother and the west side by Ken Hutchinson.
