24 - 28 September 2020
An amazing total of behavioural assays. In each assay the exploratory behaviour of the captured Knots was measured. Video: Aileen Roncoroni (NIOZ)
Taking the biometric measures of the birds
23 September 2020
Everyone 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!

Aileen, Selin and Allert set up five tents to host the birds for a couple of days until their personality assay (behavioural measurements).
An efficient assembly line for a hectical day
21 September 2020
After 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.
More countings and reading rings
19 September 2020
Still 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 2020
It 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 2020
At 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.
The behavioural assays has started
27 August 2020
One 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).

Second attempt at catching and tagging red knots
19 August 2020
When 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.
