Some notes about the Kookaburra's at Wassenaar because Wassenaar was among the first European zoos which succesfully bred the species.
European ( world ? ) first breeding was archieved by the London Zoo in 1905 but Wassenaar seemed to be the second zoo in Europe which bred this species which is now-a-days so common in zoos.
Feb. 1951 4 birds were imported directly from Australia and placed together in an outdoor aviary. 1953 the birds were split into 2 pairs and one pair was placed in the Louise hal and the other pair was left in the old outdoor aviary.
The pair in the outdoor aviary started to lay eggs in 1954 ( 1 egg laid ), 1955 ( 2 egg laid ) and 1956 ( 2 eggs laid from which at least was was fertile but didn't hatch ).
On April 24 1957 again an egg was laid and 2 days later a second egg was found.. On May 16 a chick had hatched and a day later the second egg was disappeared. The young did very well and on June 22 the young was seen for the first time outside the nest.
In 1960 another young was raised succesfully.
After these very early successes more zoos started to breed the species and in the 1980s annual about 30 to 50 young were raised in zoos worldwide.
