Stress behaviour testing

18 July 2016

This season, we are testing individual behaviour in the field. We have also designed a kind of stress test during our catches. We let the geese run through a tunnel and measure the time they need for this escape. Times are very variable. Margje places the geese in the start of the tunnel and Jesse takes the time unti the goose appears in freedom. Now we can release each individual immedeately after the catch. If there are goslings we have to keep all geese united, so the goslings can find their parents immedeately after release.
Free again.
