While Copenhagen Zoo does not have a dedicated grey heron exhibit, these birds are commonly seen within the zoo grounds. They are known to visit enclosures such as those of the seals and penguins, often arriving during feeding times to share in the food provided to these animals.

This behavior is facilitated by a nearby heron colony located in Frederiksberg Gardens, adjacent to the zoo. The colony, consisting of approximately 20-30 herons, nests on an island within the gardens. From there, the herons venture into the zoo and other parts of the city in search of food.

Visitors to Copenhagen Zoo can often observe these wild grey herons as they interact with the zoo's resident animals, providing a unique opportunity to see local wildlife in an urban setting.
