Within our bike excursions through the city of Madrid we continue looking in more detail at the nature of our city. This tour is focused on birds. Madrid, due to its location in the center of the Peninsula, is a transit and meeting place for much of our winged fauna and Manzanares is one of its main communication routes to move from one place to another. It is now, in the fall and winter, when we can observe more species of birds within the city itself. The cranes that go looking for the south and the acorns, seagulls that go up the Tagus from the Atlantic and many more species that always bring us surprises.
