IJmuiden Lesser Black-backed Gull GPS-project update: daily routines of returning adults

Over the last couple of days more Lesser Black-backed Gulls that are fitted with a GPS-logger have returned to the IJmuiden Forteiland colony, the Netherlands.

Five are back now:

  • YBHM/5962
  • YASV/5369
  • YBJC/5491
  • YAVL/5963
  • YCVN/5579

It’s very interesting to see that they are immediately picking up their daily behaviour by visiting their regular locations in Amsterdam and Hoofddorp. (Click the image for a larger view.)

About the project

(Source: http://www.uva-bits.nl/project/daily-movements-of-gulls-from-forteiland-ijmuiden/)

The tracking study is part of an ongoing collaboration between the University of Amsterdam UvA (Dr. Judy Shamoun-Baranes) and the Royal Netherlands Institute for Sea Research NIOZ (Dr. Kees Camphuysen).

The study is being conducted within the project “Interactions between birds and offshore wind farms: drivers, consequences and tools for mitigation” funded by NWO Applied and Engineering Sciences Open Technology Programme, Rijkswaterstaat and Gemini windpark.

The tracking study will provide complementary information on the movement patterns of gulls breeding along the North Sea coast, with similar objectives to the studies conducted on Texel and Schiermonnikoog.

The main aim is to identify intrinsic and external drivers of movement from fine scale flight behaviour to seasonal migrations. While adult gulls from other colonies have been tracked since 2008, little is still known about the daily movements and flight behaviour of juveniles and how this differs from adults.

This study will contribute to our knowledge on how juvenile birds develop their foraging and migration strategies and how their flight behaviour differs from adults.
