<p>&lt;em&gt;LBBG_ADULT - Lesser black-backed gulls (Larus fuscus, Laridae) breeding in Belgium&lt;/em&gt; is a bird tracking dataset published by the &lt;a href="https://www.inbo.be/en"&gt;Research Institute for Nature and Forest (INBO)&lt;/a&gt;. It contains animal tracking data collected by the LifeWatch GPS tracking network for large birds (&lt;a href="http://lifewatch.be/en/gps-tracking-network-large-birds"&gt;http://lifewatch.be/en/gps-tracking-network-large-birds&lt;/a&gt;) for the project/study &lt;strong&gt;LBBG_ADULT&lt;/strong&gt;, using trackers developed by Ornitela (&lt;a href="https://www.ornitela.com/"&gt;https://www.ornitela.com&lt;/a&gt;). The study has been operational since 2022. In total 39 individuals of lesser black-backed gull (&lt;em&gt;Larus fuscus&lt;/em&gt;) have been tagged in the breeding colony of Zeebrugge in Belgium, mainly to study their habitat use and migration behaviour. Data are automatically synced with Movebank and from there periodically archived on Zenodo (see &lt;a href="https://github.com/inbo/bird-tracking"&gt;https://github.com/inbo/bird-tracking&lt;/a&gt;).</p><p>This dataset was collected using infrastructure provided by INBO and funded by Research Foundation - Flanders (FWO) as part of the Belgian contribution to LifeWatch.</p><p>Data have been standardized to Darwin Core using the &lt;a href="https://inbo.github.io/movepub/"&gt;movepub&lt;/a&gt; R package and are downsampled to the first GPS position per hour. The original data are available in Stienen et al. (2024, &lt;a href="https://doi.org/10.5281/zenodo.12622252"&gt;https://doi.org/10.5281/zenodo.12622252&lt;/a&gt;), a deposit of Movebank study &lt;a href="https://www.movebank.org/cms/webapp?gwt_fragment=page=studies,path=study2298738353"&gt;2298738353&lt;/a&gt;.</p>
