Vermeer K. & Cullen L. (1979) Growth of Rhinoceros Auklets and Tufted Puffins, Triangle Island, British Columbia. ARDEA 67 (1-2): 22-27
Growth of young Rhinoceros Auklets and Tufted Puffins on Triangle Island, British Columbia varied between species and years, Weight increments of both species were significantly reduced at times of poor reproduction and sub-optimal feeding conditions, An exchange experiment demonstrated that the species could raise each others young and that the exchanged young adopted the diurnal and nocturnal feeding patterns as well as the growth forms of the foster species, The significance of those results are discussed.
