Описание

Bird numbers (number of nests or number of territories) of all species within fixed plots were monitored in a standardized way, in order to reveal temporal changes in breeding bird numbers at Medusa Bay. Additionally some important demographic variables were monitored to further explain these changes (i.e. arthropod abundance). Research activities also included research on breeding ecology of Brent Geese in relation to Snowy Owls.

Методы сбора

Bird migration was recorded using two methods. (1) From June 10 to July 20, migratory birds were counted daily for 1.5 hours along the coastline of Medusa Bay from the rocky ridge just south of the Willem Barentz station. (2) During the many hours of fieldwork of territory mapping all movements of non-territorial birds, except for those of common passerines were recorded per day, including number of birds and direction. In order to determine densities of breeding birds, for most species a territory mapping was performed as proposed by Willems et al. (wiwo report 77, 2002). Birds were counted in plots of 0.75 km2, 4 km2, 12 km2 or 30 km2 according to their level of abundance. A few inconspicuous species were counted by searching for nests (Temminck's Stint, Red-throated Pipit and Curlew Sandpiper). The territory mapping was performed twice, with a 10 day gap between both measurements. During a territory mapping (day time, no precipitation, no wind), all snow-free patches of tundra are visited, by walking a zigzag route through the landscape. Arthropod abundance was followed throughout the breeding season on nine series of pitfall traps. Each pitfall series consisted of 10 traps and was emptied every five days. The contents of the traps were identified to family-level.

Дополнительные метаданные

Цель The aim of this study was to focus in a standardized way on numbers (number of territories or number of nests) of all bird species present within fixed plots, in order to reveal temporal changes in breeding bird numbers at Medusa Bay, Additionally, some important demographic variables were monitored to explain changes in breeding bird numbers and breeding success. Research activities also included research on breeding ecology of Brent Geese in relation to Snowy Owls.
