Unpublished Reference Project RAVen: Validating radar technologies to study near- and offshore bird migration
The Belgian part of the North Sea is part of a very important seabird migration route through the Southern North Sea, which makes it an ideal area to study bird migration. Because of its shape, this part of the North Sea acts as a migration bottleneck, concentrating birds during migration. This study aims at cross-validating bird detection by meteorological and bird radars, mainly focusing on offshore and coastal migration, and suggesting refinements to the bird detection algorithms of both weather and dedicated bird radars. The Royal Meteorological Institute of Belgium (RMI) uses three C-band weather radars for meteorological observations, one of which is located in Jabbeke, at only a few kilometers from the Belgian coast. The Royal Belgian Institute of Natural Sciences (RBINS) has installed a Merlin bird radar (DeTect Inc.) on an offshore platform at 25km from the coast, to study the impact of offshore wind farms. The Merlin radar system consists of two identical radar antennas, one scanning in the horizontal pane and one in the vertical. They are operating at a range of 7.4km and 1.85km respectively, thus providing high resolution data. The measurements of the bird radar and the weather radar in Jabbeke are overlapping, which offers a unique situation to cross-validate the data of both types of radar and to extrapolate the high resolution data of the bird radar to the wider spatial scale of the weather radar. RBINS and RMI are joining forces in a two year project called RAVen (RAdar registrations of bird migration Validation through an interdisciplinary approach). It runs until mid-September 2018 and is funded by the Belgian Science Policy. First results (from spring 2016) already show a good correlation between the number of birds detected by both radars.

Unpublished Reference Comparing the results of four widely used automated bat identification software programs in the North Sea region
Recently a few papers were published addressing the prudency needed when using automated identification software programs to analyse recordings of bat echolocation sounds. We want to contribute to that discussion by analysing a reference dataset of bat recordings with four widely used and commercially available software programs (BatIdent, BatExplorer, Kaleidoscope and Sonochiro). The reference data were all recorded in Western-Europe with a batcorder. For most of the recordings there was a visual confirmation of the recorded species. In a few other cases certainty was obtained because the specimens were captured and released or because the recordings were made in certain areas which were outside of the range of other species (e.g. at high altitude to separate Eptesicus serotinus and Eptesicus nilssonii). After running the different programs on the reference data, we compared the outputted results. Overall, identification of the recordings to species level in this test was best with Batident (81% correct identifications), followed by Kaleidoscope (71%), Sonochiro (63%) and BatExplorer (53%). We can conclude that each of the tested programs has its own strengths and weaknesses, but none of them should be used unsupervised. Outputted results need to be checked by a trained expert. In this way, our test affirms the conclusions of previous tests in Northern Europe and the USA.
