Total estimate of oiled birds: 

The Prestige suffered hull damage in heavy seas near the coast of Galicia, Spain. It was towed to open sea where a few days later, on 19 November, the single hulled vessel broke in two and sank about 275 km west of Vigo. The Prestige is considered  one of the largest environmental disasters in Spain's history.

The affected area is a very important ecological region. It is a key site on the wintering migration routes of Atlantic seabirds, and maintains an important population of Eurasian otters, dolphins and marine turtles.

Amount and type of oiled spilled: 
63,000 tonnes of No. 2 (heavy) fuel oil
Wildlife Response: 

Oiled birds started arriving on the nearest beaches almost immediately. They continued to arrive on the shores, although never more than 83 birds a day. The wildlife response, to which international response groups were invited, was operational for over 80 days.
