Many towns and cities in Extremadura are excellent places for bird watching, as they offer ideal nesting places for birds and are close to their feeding areas. Historical buildings are usually the sites selected for nesting due to the abundance of cavities and supports as nest sites for species like White Storks in church bell towers: one of the most representative images of the region.
These buildings house large colonies of Lesser Kestrels, sometimes numbering more than 50 pairs. Western Jackdaw, Pallid and Common Swifts, and Barn Owl also nest in the same places. On large bridges, some of them from Roman times, Alpine Swifts breed.
The urban stretches of the Guadiana River as it passes through Mérida and Badajoz are favoured by herons and egrets to establish their bustling breeding colonies, completely oblivious to intense human activity. Equally striking are the colonies of House Martins on many buildings and bridges, sharing urban centres with Barn Swallows and occasionally Crag Martins.
Extremadura is one of the few European regions that has designated SPAs within urban centres, currently 18 towns and cities are protected for their importance for birds, especially for their Lesser Kestrel colonies: Cáceres, Plasencia, Trujillo, Llerena, Zafra, Almendralejo, Acedera, Alburquerque, Brozas, Belvís de Monroy, Fuente de Cantos, Garrovillas, Guareña, Jerez de los Caballeros, Ribera del Fresno, San Vicente de Alcántara, Saucedilla and Jaraíz de La Vera. Finally, the Casa de la Enjarada SPA, in the vicinity of Cáceres.
