Birds and fauna

The municipality has a special relevance in its population of birds, with 92 species during the reproductive period, which represent 48% of the species present in the Community of Madrid and 32% of the species present in Spain in that period, such and as collected by the inventory carried out by SEO / Birdlife.

The configuration of the landscape in a mosaic of holm oaks with rainfed crops and meadows conditions a diversity of environments and a mixture of patches of natural vegetation with cultivated areas that gives the area an almost permanent "edge effect", and that makes the diversity in species is certainly high.

Part of the municipality is under an Important Bird Area (IBA) called “Baja Alcarria”. The part of the municipal area that is included is part of the nesting and feeding territory of one of the Bonelli's eagle pairs, a raptor classified as an endangered species

On the other hand, there are two species in Olmeda classified as "sensitive to habitat alteration": the little bustard and the golden eagle. The little bustard is a bird linked to steppe environments, and although it is not abundant, it breeds scattered in the same plain that Bonelli's eagle uses as a feeding area. The golden eagle is frequently sighted because they have a reproductive nucleus in an adjoining municipality.

There are three other species with a high degree of threat according to the Regional Catalog: Montagu's harrier, peregrine falcon and eagle owl.

There are other after species of interest in the area such as the European short-toed eagle, pale harrier, booted harrier, European rail, common stone curlew, barn owl, red-necked nightjar, Eurasian wryneck, calandria, redstart, black wheatear, warbler and royal shrike.

In addition to these birds of interest, urban and orchard areas are home to countless species such as goldfinches, chickadees, blue tit, finches, black redstart, robins, nightingales, among many others that are responsible for beautifying walks and decorating nights with their songs.

The summer skies of Olmeda are crossed by swallows, airplanes, swifts, turtledoves and starlings. And at night for scops and owls.
