Swans, Geese, Ducks, and, of course Pigeons
Frederiksberg Park boasts a rich bird life with an established population of Herons and Graylags - as well as being a bird sanctuary for many other obviously hungry bird species.
I saw a Heron sitting in a tree but missed the photo.
I wouldn't know a Graylag if I fell over it.
There are also now a few white peacocks which are very popular...if you can find one.
