Short visits reveal consistent patterns of interyear and intercolony variation in seabird nestling diet and performance

D.F. Bertram, T. Golumbia, G.K. Davoren, A. Harfenist, and J. Brown  Abstract: To investigate the utility of short visits to seabird colonies to gauge nestling growth performance and diet, in 4 consecutive years (1995–1998) we measured nestling development and diet of Rhinoceros Auklets (Cerorhinca monocerata) at three colonies in British Columbia: Seabird Rocks, Triangle Island,
