Murres con- siderably outnumber all others, but the summer population also includes other inter- esting species with similar breeding requirements. In the center of the island there is an area of scantv grass occupied by the nests of glaucous gulls, a powerful, predatory species that preys on the eggs and young of other birds when left unguarded. In the exhibit may also be seen red-faced cormorants, glaucous-winged gulls. Pacific kitti- wakes, and clown-like horned puffins. Other residents of this amazing bird metropolis, not shown in the exhibit, are the tufted puffin, the crested paroquet, the least auklet and the red-legged kittiwake. 45.
