<p>&lt;em&gt;MH_WATERLAND - Western marsh harriers (Circus aeruginosus, Accipitridae) breeding near the Belgium-Netherlands border&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;MH_WATERLAND&lt;/strong&gt;, using trackers developed by the University of Amsterdam Bird Tracking System (UvA-BiTS, &lt;a href="http://www.uva-bits.nl"&gt;http://www.uva-bits.nl&lt;/a&gt;). The study was operational from 2013 until 2018. In total 7 individuals of western marsh harrier (&lt;em&gt;Circus aeruginosus&lt;/em&gt;) have been tagged in their breeding area near the Belgium-Netherlands border (provinces of East Flanders in Belgium and Zeeland in the Netherlands), mainly to study their habitat use and migration behaviour. Data are uploaded from the UvA-BiTS database to Movebank and from there archived on Zenodo (see &lt;a href="https://github.com/inbo/bird-tracking"&gt;https://github.com/inbo/bird-tracking&lt;/a&gt;). No new data are expected.</p><p>See Milotic et al.
