GPS halsbanden | 23 juni 2020 |
|
We hebben toestemming om 24 vogels een GPS halsband om te geven. Deze halsbanden registreren iedere 15 minuten de precieze locatie van de gans en doen dat voor meerdere jaren dankzij zonnepanelen en oplaadbare batterijen. Zodra de gans een GSM netwerk passeert, worden de gegevens automatisch doorgegeven. Om de ganzen te vangen gebruiken we een vishengel met aan het eind een stropje. Zo kunnen we de ganzen alleen vangen als de eieren uitkomen. Dan blijven de ganzen dicht bij het nest. | |
