October 12, 2015 – Ivory Gull (Pagophila eburnea)
Requested by: @taylorrbranham
These small gulls spend most of their time in the Arctic, breeding in parts of Canada, Greenland, Norway, and Russia. They eat fish, marine invertebrates, small mammals, carrion, and seal waste. Like owls and many other birds, they regurgitate pellets made up of the indigestible parts of their diet, such as bones and fur. Breeding on cliffs and rocky islands, they use mosses, dried grass, wood fragments, feathers, seaweed, lichen, and mud to build their nests. They are classified as Near Threatened by the IUCN, as they have experienced a large decline since the 1980s. Disturbance by humans, loss of pack ice due to climate change, pollution, and hunting seem to be the main threats to their population.
