The Arizona Game and Fish Department released new photos Friday of another lamb born in the Catalina Mountains north of Tucson.
So far, three lambs have been spotted in the Catalinas, born to bighorns relocated there from Yuma.
Game and Fish said this week that 12 of the 31 bighorns relocated have died, most being killed by mountain lions.
The agency said at least three lambs have been seen in the mountains.
