    Seven types of bees once found in abundance in Hawaii but now facing extinction on Friday became the first bees to be added to the federal list of endangered and threatened species, according to U.S. wildlife managers.

 

    The listing decision, published on Friday in the Federal Register, classifies seven varieties of yellow-faced or masked bees as endangered, due to such factors as habitat loss, wildfires and the invasion of nonnative plants and insects.

 

    The bees, so named for yellow-to-white facial markings, once crowded Hawaii and Maui but recent surveys found their populations have plunged in the same fashion as other types of wild bees - and some commercial ones - elsewher in the United States, federal wildlife managers said.
