Miralrío is other pond in the Southeast Madrid Regional Park. As all of the ponds in this park is the result of flooding and recovery os sand pits for building. This one is very buried in the field and less walkable than other ponds in the area, which together with its location next to an industrial estate, makes it more lonely. Which is positive for the tranquility of birds. In fact there is a place choosen for sleeping for the herons. The first thing I saw was a couple of groups of cormorants. And the little and cattle egrets, great crested grebes, shovelers, and other birds.
