Sex determination of South Island saddlebacks (Philesturnus carunculatus carunculatus) using discriminant function analysis | Notornis and Birds New Zealand

[摘要] Male and female South Is saddlebacks (Philesturnus carunculatus carunculatus) have monomorphic plumage characteristics and are not easily distinguishable. In this study, we developed discriminant functions to classify males and females using birds of known sex from Ulva I. Three discriminant functions using tarsus length, body mass, and a combination of tarsus length and body mass could classify birds with 90% accuracy.
