WATLAS fieldwork 2020 on the island of Griend
28 September 2020An overview of the 2020 fieldwork season. From birdwatching and ring reading, catching red knots at night to processing the birds. Video: Aileen Roncoroni
Process of behavioural assays of captured wild Knots
24 - 28 September 2020An amazing total of behavioural assays. In each assay the exploratory behaviour of the captured Knots was measured. Video: Aileen Roncoroni (NIOZ)
23 September 2020Everyone was feeling tired. The last three days we have only slept for a few hours every night. But we are delighted, as we caught 116 Red Knots!
21 September 2020They will make a documentary about bird migration, and how these birds connect different people from different countries all around the world.
21 September 2020Aileen, Selin and Allert set up five tents to host the birds for a couple of days until their personality assay (behavioural measurements).
21 September 2020After only five hours sleep, we arranged an efficient 'assembly line' to process the 49 Knots that we caught the previous night. Within a few hours all birds were processed.
19 September 2020Still no birds caught. It seemed a good time for colour-ring reading. From the height of the hut we saw plenty of Red Knots on the mudflats north of the island.
17 September 2020To get an idea of where there are high chances of catching the Knots, we consult the WATLAS tracking data of the night before. The south of the Island!
17 September 2020It is finally time for our third (and hopefully successful) catching attempt of the year! Once again, we travelled in two separate groups, because of corona regulations.
27 August 2020At the end of the day, the adult birds were colour-ringed and released with a WATLAS tag. Some younger birds will be retested the following day.
27 August 2020One at a time, the birds are taking out of their aviary and brought into a crate for two hours before testing. This is to acclamaties them to being alone (briefly).
25 August 2020Knots in their temporarily home on Griend awaiting for the test in the experimental arena for assaying their behaviour of knots (their personality)
25 August 2020We built the lower half of the arena, a 2m x 2m pool and then collected several containers of sea water from the gulley to the west of the island.
25 August 2020Job takes various biometric measurements of the birds, such as bill length, wing length and body mass and a small blood sample to extract DNA.
25 August 2020A large storm was on its way and since another night of catching looked impossible, it was better to get the Navicula safely back to the NIOZ harbour.
24 August 2020Testing the accuracy of WATLAS localizations at some of the further points on the mudflat. Unfortunately, strong winds made it a very rough ride.
23 August 2020The weather was not pleasant and heavy showers and wind made the work challenging. High wind speeds, blown one of the solar panels upside down.
19 August 2020When we arrived at Griend, we unloaded the equipment and luggage onto a rubber boat to take to shore. Because of low-tide, a 2km walk to the island.
26 July 2020The knots are equipped with WATLAS tags, enabling us to follow them out there in the Wadden Sea and link their personality with foraging movements in the field.
Tracking birds in the Dutch Wadden Sea
23 July 2020Interview with the WATLAS fieldwork crew on tracking birds in the Wadden Sea in NEMO Kennislink. Why are birds tagged and what do we want to find out?
20 July 2020The receivers are ready to detect red knot locations. The only thing left is to tag the birds with the lightweight tags which we will begin next week.
15 July 2020After PhD student, Misha Zhemchuzhnikov, had designed a wonderful WATLAS logo, Allert ordered a batch of WATLAS t-shirts to celebrate the occasion.
Constructing the temporary receivers on the mudflats
14 July 2020Fieldwork 2020. Team 'Canutus' building the majority of the scaffold for receiver number 2, before the tide pushed them back to their ship for the night.
A more efficient management of the Wadden Sea
6 December 2019For more efficient management of the Wadden Sea, applied questions should be embedded into long-term scientific research programs Friesch Dagblad (in Dutch).
10 October 2019A postdoctoral position of max 3 years on movement and spatial ecology of shorebirds under the supervision of Allert Bijleveld. Closing date: 5 December 2019
Big Brother in Wadden Sea watching the birds
29 September 2019You can already sea that the shorebirds in the Wadden Sea have to fly far to get food. It is sometimes about distances of about 80 kilometers Omrop Fryslan.
Transmitter system follows individual bird movements
10 March 2019Following in real time Red Knots in the western Dutch Wadden Sea. An interview with Allert Bijleveld in magazine 'De Ingenieur' (in Dutch).
16 July 2019How social networks facilitate social learning in the wild is largely unknown. Allert Bijleveld investigates this by tracking knots in the wild with the WATLAS system.
28 September 2018Sanderlings weighing only 50 grams fly long distances in the Wadden Sea with every change of tide. This is evident from the first results of the monitoring experiment.
18 July 2018By tracking shorebirds on their migration and within the Wadden Sea, we will understand why the Wadden Sea is so important to them.
