To gain an understanding of the birds of Galicia this spectacular area of eastern Ourense should not be ignored. Nestled in the valley of the Tamega river, a tributary of the Duero, some 142 species of birds call home to the area, many of which are difficult to find elsewhere in Galicia. Between late April and late June, Oímbra, Monterrei and Verín are at their best for bird watching expeditions, although a hike in December and January can also provide ample sightings of wintering birds.
