Бесконтактный метод определения пола такахе Porphyrio porphyrio (Rallidae, Gruiformes) по абрису клюва: графический и статистические приемы

Виноградов А. А., Серов А. А., Зиновьев А. В.

Here we present the results of applying the method of non-contact sexing of
birds by the profile beak outlines to a rare flightless rallid from New
Zealand – takahē. The graphic stage of the method made it possible to
identify visual differences in the profile outlines of the beak of males and
females. The reliability of the differences found was confirmed by a set of
statistical analysis techniques that showed almost 100 percent effectiveness
of the proposed method.
