Migration patterns in birds vary in space and time. Spatial patterns include chain, leap frog, and telescopic migration. Temporal patterns such as migration duration, number and duration of stopovers may vary according to breeding latitude, sex and season. This study aimed to verify these patterns in a long-distance migrant, the Eurasian curlew (Numenius arquata arquata), and to provide a synopsis of spatio-temporal migration patterns in this species of concern throughout the East Atlantic Flyway. We...

The ULR-repro3 GPS data reanalysis solution (aka ULR7a)

The ULR analysis center has participated in the third reprocessing campaign (repro3) of the International GNSS Service (IGS). Its ULR-repro3 solution (aka ULR7) included 601 stations for which the GNSS data available between 2000.0 and 2021.0 was reprocessed using the models and corrections adopted by the IGS for repro3. The main steps and features of ULR-repro3 reanalysis are as follows. First, daily GNSS solutions were computed using a free-network weighted least squares adjustment strategy. That...

Feeding sites characteristics of the Northern shoveler Spatula clypeata in prenuptial stopover

Axelle Moreau, Clément Rousseau, Pierrick Bocher, Christine Dupuy & Sébastien Farau
Dabbling ducks choose a multitude of habitats throughout their life cycle. This choice depends on the abundance, diversity, and accessibility of food resources. Wetlands such as the Marais breton and Marais poitevin (Atlantic coast, France) are common habitats for several Anatidae, especially during their prenuptial migration. However, studies on the food ecology of Anatidae at stopover sites are limited. Therefore, this study focused on the Northern shoveler Spatula clypeata, a species that regularly inhabits the...
