To what type of feeder is the ecological niche of the Sabine's Gull in the Arctic compared, due to its gleaning of tiny, surface-level prey?
Answer
A small shorebird
The feeding style adopted by the Xeme while foraging on the Arctic tundra demonstrates a niche distinct from many other gull species, which are often bulk feeders. The Sabine's Gull in this environment specializes in gleaning minute prey items directly from the surface of the ground or water. This focused method of capturing tiny, surface-level prey items is explicitly compared in its ecological function and style to the feeding behavior characteristic of a small shorebird.
