A seabird known as the brown booby is nesting for the first time in California's Channel Islands National Park.
The discovery announced Tuesday means the bird that is usually tropical or subtropical appears to have extended its range further north than previously seen.
A news release from the park says biologists discovered four nests and 102 individual birds on Sutil Island, the smallest in the chain. Adult birds appeared to be either incubating eggs or tending to young in the nests.
The discovery means there are now 14 species breeding seabirds that rely on the park.
The brown booby is known for making spectacular dives for surface fish from up to 50 feet. They lay their eggs on bare ground on islands, then make nests with sticks, rocks and vegetation.
