Lesser White-fronted Goose expedition to Eastern Syria, February 2007

Lesser White-fronted Goose (Anser erythropus) Science Article 3 abstract The expedition was carried out on 9-11 February 2007, as planned in earlier correspondence with the team working on the protection of Lesser White-fronted Goose Anser erythropus as well as Syrian and regional ornithologists. Participants included Anssi Kullberg currently working for the Finnish Embassy in Damascus […]

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% […]

Site fidelity of Icelandic Greylag Geese between winters

Greylag Goose (Anser anser) Science Article 9 abstract Britain supports almost the entire Icelandic population of Greylag Geese Anser anser in winter and has a special responsibility for the conservation of these birds. To facilitate the successful management of this population, the aim of this analysis was to ascertain the degree of site fidelity on […]

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. In July the geese gathered in the central Seewinkel area (main gathering place Lange Lacke). […]

Greylag geese (Anser anser)-Scirpus maritimus relationships in a newly colonised wintering area in the Camargue

Greylag Goose (Anser anser) Science Article 10 abstract In order to evaluate the proportion of Scirpus maritimus tubers consumed by a growing population of wintering Greylag goose (Anser anser) in Camargue, Southern France, we (1) measured the biomass of Scirpus maritimus tubers on the main resting and feeding marsh for geese in the area; and […]

Egg predation in reedbed nesting Greylag Geese Anser anser in Vejlerne, Denmark.

Greylag Goose (Anser anser) Science Article 7 abstract Egg predation in Greylag Geese Anser anser nesting in reedbeds was studied at three sites in Vejlerne (NW Denmark). Overall, 34% of all clutches hatched successfully (range 26-53%), while at least 34% of all nests were abandoned. Avian predation of clutches was particularly high on one site […]

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, […]

Food, feeding-behavior and nutritional ecology of wintering Greylag Geese Anser anser.

Greylag Goose (Anser anser) Science Article 4 abstract Just after arrival in early autumn, Greylag Geese Anser anser wintering in the Marismas of the Guadalquivir (SW Spain) concentrated on Scirpus litoralis areas, but moved to Scirpus maritimus areas as soon as these zones were flooded after autumn rains. In both Scirpus habitats the diet was […]
