Exploitation of a new staging area in the Dutch Wadden Sea by Greylag Geese Anser anser: The importance of food-plant dynamics.

Greylag Goose (Anser anser) Science Article 8 abstract The colonisation by Greylag Geese Anser anser of a new autumn migration staging area was studied on the island of Schiermonnikoog, The Netherlands. Over 500 Greylag Geese first visited the island in 1991. During subsequent years, peak numbers rose to 700-900 birds. The geese most likely originated […]

Wintering Greylag Geese Anser anser in North-Africa.

Greylag Goose (Anser anser) Science Article 3 abstract Goose counts at the three major wintering grounds of North Africa from 1981/82 to 1988/89 are presented and discussed. The origin of the Greylag Geese wintering there is documented by individually marked geese. These neck-banded geese also proved that movements occur between Tunisia and Algeria and supported […]

Remote sensing as a technique to assess reedbed suitability for nesting Greylag Geese Anser anser.

Greylag Goose (Anser anser) Science Article 1 abstract We studied Greylag Goose Anser anser nest distribution in relation to reed stem density in the Tgmmerby Fjord reedbed, Denmark, using rial photography to locate nests . Digitised photographs were used to establish a relationship be tween spectral signature and reed stem density. This technique classified 71% […]

On the spatial-distribution and social-organization of neck-banded Greylag Geese Anser anser in their breeding area of Lake Neusiedl, Austria

Greylag Goose (Anser anser) Science Article 5 abstract Although goslings are known to move up to 10 km in their first days of life, juvenile geese only moved short distances (up to 1 km) from their ringing sites after ringing.

Nocturnal feeding in moulting Greylag Geese Anser anser- An anti-predator response?

Greylag Goose (Anser anser) Science Article 6 abstract The diurnal activity patterns of Greylag Geese were studied at a Danish moulting site. Before moulting, Greylag Geese foraged throughout the 24 hour period, but changed to nocturnal feeding behaviour exclusively and roosted on offshore islets during the day, as they became flightless. As the moult progressed, […]
