Sterntjes ringen | 14 juli 2015 |
| Vandaag gaan janwillem en Maarten naar Gerøya. Op dit eiland nestelen in de meeste jaren erg veel sternen.
We tellen er dit jaar 150 broedpaar, wat weinig is. Hopewel volwassen noordse sternen ontzettend korte pootjes hebben, zijn de poten al bijna volwassen grootte als het jong geboren wordt. Dat betekent dat we al bij erg jonge kuikens metalen ringen kunnen omdoen. Omdat we geïnteresseerd zijn in overleving hebben we onze ringspullen meegenomen. | |

| Het jonkie vlucht van ons weg, totdat we vlakbij zijn. Dan houdt het zich dood. | |
| Geboorte van een stern. Janwillem ontdekte dit nestje. Het kuiken is hard aan het werk zich te bevrijden uit het ei en dat is gevangen in een paar seconden video. | |
| Prachtig kuiken op de toendra. | |
