Brown Thrasher

Toxostoma rufum

Introduction

This common bird of North American woodlands has only been recorded once in Britain, in November 1966, when a stray individual unexpectedly turned up in Dorset and remained through to the following February.

Brown Thrasher populations tend to be resident or short-distance migrants, underlining the exceptional nature of the 1966/67 record.
