More than 500 million birds representing 500 species migrate across Saudi Arabia every year through the Red Sea, according to an expert in the Kingdom.
Dr. Mohammed Shubrak, a Saudi Wildlife Authority adviser, said that birds migrating from their habitats to other habitats reflected biodiversity, since most species were well-known and classified.
He explained that the route of migratory birds covered the yearly migration from nesting to resting and feeding grounds.
During migration, birds made many physiological adaptations such as increasing their fat percentage, reducing the size of their organs and increasing the size of their feathers. To migrate from one place to another, birds also adopted different behavior according to their size and species.
