Sabine's gull insect larvae taken include terrestrial and aquatic beetles, springtails, craneflies, mosquitos, midges, and flower flies (Syrphidae). Sabine's gull The Sabine's gull ("Xema sabini"), also known as the fork-tailed gull or xeme, is a small gull. Its generic placement is disputed; some authors treat it as the sole species in the genus Xema as Xema sabini, while others retain it in the genus "Larus" as Larus sabini. The Sabine's gull breeds in colonies on coasts and tundra, laying two or three spotted olive-brown eggs in a ground nest lined with grass. It is very pelagic outside the breeding season. It takes
Fork-tailed storm petrel of the diet of river otters, gulls, and raptors. Further, introduced predators like foxes, martens, and raccoons have a significant impact on breeding populations. To defend themselves, fork-tailed storm petrels can eject their stomach oil at an incoming threat. Fork-tailed storm petrels generally coexist peacefully with other seabirds, where they can be seen sharing breeding habitat with tufted puffins. In some cases, aggression can be observed, where they are known to steal food from Leach's storm petrels. Being widespread and abundant, the fork-tailed storm petrel is not threatened with extinction. However, humans impact their life history in many ways. As
