The exception to the rule: retreating ice front makes Bewick's swans Cygnus columbianus bewickii migrate slower in spring than in autumn

RJM Nuijten, A Kölzsch, JA Van Gils… - Journal of Avian …, 2014‏ - Wiley Online Library
In the vast majority of migratory bird species studied so far, spring migration has been found

Skip** swans: fuelling rates and wind conditions determine differential use of migratory stopover sites of Bewick's Swans Cygnus bewickii

JH Beekman, BA Nolet, M Klaassen - Ardea, 2002‏ - research.rug.nl
Some migratory birds refuel at stopover sites that they by-pass on the return trip. In theory,
this skip** behaviour is only expected in time-selected migrants when the overflown site is …

Foraging costs and accessibility as determinants of giving‐up densities in a swan‐pondweed system

BA Nolet, VN Fuld, MEC Van Rijswijk - Oikos, 2006‏ - Wiley Online Library
We measured the patch use behaviour of Bewick's swans (Cygnus columbianus bewickii)
feeding on below ground tubers of fennel pondweed (Potamogeton pectinatus). We …

The role of herbivorous water birds in aquatic systems through interactions with aquatic macrophytes, with special reference to the Bewick's Swan–Fennel Pondweed …

M Klaassen, BA Nolet - Hydrobiologia, 2007‏ - Springer
The role of aquatic macrophytes in stimulating biodiversity and maintaining clear waters is
currently undisputed. The management of (eutrophic) shallow waters is therefore often …
