The odyssey of the Bewick’s Swan – another route to Greece
After almost 20 years of surveying the impressive increase in the number of Bewick’s Swans wintering on the Evros Delta (Greece), from a first observation of 25 birds in February 1997 to a peak at 8,400 individuals during February 2016, there is much puzzlement about their breeding grounds and migration route.

Mute Swan grazing in chalk streams
Thanks to their abundant aquatic plants the chalk streams of southern and eastern England are an ecosystem of high conservation value, especially for invertebrates and fish. Over recent decades, fisheries and conservation interests have become concerned that the foraging by Mute Swans (Cygnus olor) on aquatic plants degrades the habitat of invertebrates, fish and other animals.

Tracking Projects
Serial development of wind farms along migration routes are an important consideration in determining the potential cumulative effect of these developments on populations, but the extent to which both offshore and onshore wind farms occur along migration routes has received relatively little attention.

Addressing the Bewick’s Swan decline
In 2014, the Wildfowl & Wetlands Trust (WWT) launched the successful ‘Hope for Swans’ appeal to fund an ongoing research programme to investigate the causes of the population decline. This programme will draw together Bewick’s Swan researchers from across different range countries. Read more →
