The Common Raven (Corvus corax) ranges throughout the Holarctic, but many life-history attributes of this species, including mean lifespan, age at first breeding, age-specific fecundity, and other important variables, remain poorly documented (Boarman and Heinrich 1999). During the spring of 2001, we observed a single pair of ravens successfully rear two broods from a nest located on the campus of the University of California, Riverside. Prior to our observations, ravens had been known to produce only replacement clutches after loss of eggs (Bowles and Decker 1930) or nestlings (Stiehl 1985).
