An unprecedented influx of Black-throated Thrushes Turdus atrogularis to the United Arab Emirates in winter 2016/17

摘要

We document an influx of unprecedented extent of Black-throated Thrushes to the United Arab Emirates in the winter of 2016/17, a single winter (November to March) in which 48% of all the records of the species from the UAE from 1990 to 2019 were made. Comparative data from adjacent countries are also presented, compiled mainly from the bi-annual Around the Region summaries published in Sandgrouse. From this analysis it is clear that the influx of Black-throated Thrushes in the UAE was closely matched in neighbouring countries and, to a lesser extent, much further afield, and may have resulted from lower than average temperatures further north in the usual wintering range.
