摘要我们描述了从2008年12月到2010年3月在伊利诺斯州西北部对一只双侧雌雄同体的北方红衣主教（Cardinalis cardinalis）的行为观察。这只鸟的左半身呈现出雄性红衣主教典型的鲜红色，而右半部分则呈现出雌性红衣主教的暗褐灰色。我们观察了40多天的鸟，大多是在附近的喂鸟。它从来没有与另一位红衣主教配对，从来没有听到过发声，也没有受到其他红衣主教的任何不寻常的争斗行为。这些观察结果是野生双雌雄同体鸟类中最广泛的。
ABSTRACT We describe behavioral observations of a bilateral gynandromorph Northern Cardinal (Cardinalis cardinalis) in northwestern Illinois from December 2008 through March 2010. The bird exhibited the typical bright red color of a male cardinal on the left half of its body, and the dull brownish-gray appearance of a female cardinal on the right half. We observed the bird more than 40 days, mostly in the vicinity of bird feeders. It was never paired with another cardinal, was never heard vocalizing, and was not subjected to any unusual agonistic behaviors from other cardinals. These observations are among the most extensive of any bilateral gynandromorph bird in the wild.
