🐺Island fox
El zorro isleño o zorro gris de las islas (Urocyon littoralis) es un pequeño cánido en peligro de extinción que solo vive en las Islas Santa Bárbara, un pequeño archipiélago situado frente a las costas de California. Es una de las dos especies actuales clasificadas en el género Urocyon, siendo la otra el zorro gris (Urocyon cinereoargenteus), su antecesor en el continente. Es el zorro de menor tamaño de América del Norte y uno de los más pequeños del mundo, pues rivaliza por este título con el fenec (Fennecus zerda) de África. La población del zorro isleño descendió fuertemente durante la década de los 90 a causa de las enfermedades introducidas en el archipiélago, la actividad humana y la depredación del águila real. Desde 2004, las cuatro subespecies más amenazadas están protegidas y se ha puesto en marcha planes de conservación de su hábitat y de cría en cautividad.
