The mother goose in the picture has been ringed, with two rings, one blue, one white, with the letter V and the number 3. The letter V is on the white ring, righthand side and the number 3 is on the blue ring, lefthand side. She was known to Egyptian goose researchers as V3.
The photo is from 6 May 2014. Then, V3 had to care for the youngsters on her own. On 12 or 13 May, a car killed her. An animal rescue center took care of the goslings.
For several years V3 had her nest at the section of the brook across the President Kennedylaan, opposite the Museon museum.
The two couples met often (in 2013 and earlier) when the Canada Geese and their goslings crossed the busy President Kennedylaan to graze and to swim in this section of the brook.
Here is Lizia’s map of the surroundings of the two nests.
This video is about catching Egyptian geese in the Zuiderpark in The Hague for ringing them.
