Site description The Rock of Gibraltar is dominated by a dense cover of maquis and garrigue, including many important fruit-bearing shrubs that support large passerine populations on passage and during the winter.

Key Biodiversity Gibraltar is a well-known migratory bottleneck site for birds of prey, with an estimated 250,000 raptors crossing the Strait in a season. If the winds are right then most of these pass over Gibraltar, and numbers may in fact be higher. It is also a stop-over site for passerines and near-passerines, with a rapid turnover of birds on passage during both northward and southward migration.
