Abstract: | Sex of pheasants (Phasianus colchicus) can be determined by color patterns of the outer primaries and primary coverts. Primaries from females typically show light-colored bars that meet the rachis at right angles along its entire length. Males typically have no pattern on the ends of their primaries, or primaries of males have a more diffuse color pattern than primaries of females. When males have a barred pattern, the bars are usually wedge-shaped and meet the rachis with the point of the wedge at an angle. Both game-farm and wild stock in juvenal plumage were sexed with less accuracy than older birds. After reviewing brief instructions and looking at several sample wings, observers using this technique averaged 96 percent accuracy for sexing game-farm birds and 93 percent accuracy for wild stock of all ages. |
