Sooty Gulls forage on the shore. Another peek at Seabirds v4 which should be out in a few days. The Sooty Gull is found in Bahrain, Djibouti, Egypt, Eritrea, India, Iran, Israel, Jordan, Kenya, Lebanon, Maldives, Mozambique, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, United Arab Emirates, and Yemen. It is a coastal bird, seldom going further out to sea than about 10 km (6 mi) beyond coastal reefs although it has occasionally been seen 140 km (87 mi) from land. It frequents ports and harbors, the coast, inshore islands and the intertidal zone. It is a predator and scavenger. It feeds on discarded fish and fish offal, other small fish that it catches itself, prawns, newly hatched turtles and the eggs and chicks of other sea birds. The European Green crab comes in many colors (despite its name). The color varies greatly, from green to brown, gray, or red. This variation has a genetic component, but is largely due to local environmental factors. In particular, individuals which delay molting become red-colored rather than green. Red individuals are stronger and more aggressive, but are less tolerant of environmental stresses, such as low salinity or hypoxia. Juvenile crabs on average display greater patterning than adults. It is a worldwide invasive species, listed among the 100 of the World's Worst Invasive Alien Species. It is native to the north-east Atlantic Ocean and Baltic Sea, but has colonized similar habitats in Australia, South Africa, South America, and both Atlantic and Pacific Coasts of North America.
