Diagnosis
ReferenceDiagnosis
D. T. Ksepka et al. 2012Kairuku grebneffi differs from K. waitaki by the straight tip of the upper beak, patella with more proximodistally elongate articular surface for femur, dorsoplantarly deeper hy- potarsus, and less concave medial margin of the tarsometatarsus. All specimens are larger than the K. waitaki holotype, but given limited sample size and the range of intraspecific size variation in penguins, this difference may not be diagnostic.
