Brandgans im Burscough, Lancashire, UK. 11tth Januar 2017. Wildes Leben bedroht als Martin Mere steht vor Schließung. In Reaktion auf die anhaltende, erhöhte Gefahr von H5N8 hoch pathogenen Aviären Influenza sollen die bestehenden Avian Influenza Prävention Zonen bis 28 Februar in Kraft bleiben. Eine Belastung des H5N1-Typs des Vogelgrippe-Virus, die im Jahr 1997 entstanden wurde als die wahrscheinlichste Quelle für eine künftige Grippepandemie identifiziert.

One of the most attractive of our waterfowl, the goose-like shelduck is renowned for its spectacular moult gatherings along the northern coast of Germany. These concentrations are often enormous, the most famous one is the German Waddenzee reaching over 100, 000 birds and including most of the north-west European population: Britain, Ireland, Belgium, Holland, Denmark, Scandinavia, north Germany, north Poland and the Baltic States. A smaller concentration of up to 4000 assembles in Bridgwater Bay (probably consisting mostly of Irish breeders) whilst other moult-sites include the Firth of Forth and the Wash. The Waddenzee consists of many square miles of gently shelving sand and mudbanks largely covered at high water. All shelduck except those bred during the year need to renew wing and tail feathers simultaneously. For about four weeks they are unable to fly at all. The first flights of our shelduck — probably mostly immatures not yet breeding and moulting flight features for the first time — cross the North Sea by July. Adults follow throughout the month with new arrivals during August and even September. Late arrivals are perhaps birds which have delayed migrating until the young they have cared for are independent. Shelduck broods readily unite to form packs with only a very few adults in attendance. Fortunate observers have seen shelduck on actual migration. At Scolt Head Island following unsettled weather a total approaching 4000 has been recorded heading north-east during a four-day movement. On another occasion 2500 shelduck were watched at dusk moving north off Wolferton in groups of between 100 and 150. At times Breydon Water provides a mid-summer staging post for a thousand or more shelduck. Shelduck breed in some numbers, along the Norfolk shore of The Wash and along the north coast. Inland breeding has become widespread with pairs nesting regularly at ten or more Broadland localities (including one within four miles of Norwich).
