Artis is not just the oldest zoo in the Netherlands. It is also one of just three places in the Netherlands with (small) black-crowned night heron colonies. The other two are Rotterdam zoo and the Ijssel river region.
Today, a black-crowned night heron took a fish from a bucket in the pelican enclosure, pursued by a jealous grey heron. Like black-crowned night herons, grey herons live freely in and around the zoo. The black-crowned night herons are in their breeding season now, with adults feeding juveniles; like in a tree in the Aldabra tortoise enclosure.
There is breeding season for the Artis griffon vultures as well. On 20 April, a chick was born and it is doing well. The big vulture cage has a fence with holes big enough for smaller birds like magpies to come inside and join the vultures in feeding; as happens with vultures living in the wild as well. There used to be ravens in the cage, but not anymore. The Egyptian vulture has been moved to another cage.
