LBBG_JUVENILE - Juvenile lesser black-backed gulls (Larus fuscus, Laridae) and herring gulls (Larus argentatus, Laridae) hatched in Zeebrugge (Belgium) is a bird tracking dataset published by the Research Institute for Nature and Forest (INBO). It contains animal tracking data collected by the LifeWatch GPS tracking network for large birds (http://lifewatch.be/en/gps-tracking-network-large-birds) for the project/study LBBG_JUVENILE, using trackers developed by Ornitela (https://www.ornitela.com). The study has been operational since 2020. In total 92 individuals of lesser black-backed gull (Larus fuscus) and European herring gull (Larus argentatus) have been tagged shortly after fledging in the colony of Zeebrugge, mainly to study their habitat use and migration behaviour. Data are automatically synced with Movebank and from there periodically archived on Zenodo (see https://github.com/inbo/bird-tracking).

This dataset was collected using infrastructure provided by INBO and funded by Research Foundation - Flanders (FWO) as part of the Belgian contribution to LifeWatch.

Data have been standardized to Darwin Core using the movepub R package and are subsampled to the first GPS position per hour. The original data are available in Stienen et al. (2026, https://doi.org/10.5281/zenodo.22083230), a deposit of Movebank study 1259686571.
