摘要

两性二态性定义了军舰鸟（军舰鸟科）的求偶行为，雄性军舰鸟会膨胀鲜红色的袋子来吸引配偶。我们记录了在较小的（Fregata ariel）和圣诞岛军舰鸟（F. andrewsi）中罕见的雌性正常育儿袋膨胀的病例。这种先前未记载的行为可能不是一种适应功能，而可能反映了生理异常（雄激素过多）或内分泌干扰化学物质，值得进一步研究。

Anomalous Gular Pouch Displays in Female Lesser (Fregata ariel) and Christmas Island Frigatebirds (F. andrewsi)

Sexual dimorphism defines frigatebird (Fregatidae) courtship, with males inflating bright red gular pouches to attract mates. We document rare cases of female gular pouch inflation in Lesser (Fregata ariel) and Christmas Island Frigatebirds (F. andrewsi). This previously undocumented behavior likely does not serve an adaptive function but may reflect physiological anomalies (hyperandrogenism) or endocrine-disrupting chemicals, warranting further investigation.

期刊介绍： Ranked by the ISI index, Biotropica is a highly regarded source of original research on the ecology, conservation and management of all tropical ecosystems, and on the evolution, behavior, and population biology of tropical organisms. Published on behalf of the Association of Tropical Biology and Conservation, the journal''s Special Issues and Special Sections quickly become indispensable references for researchers in the field. Biotropica publishes timely Papers, Reviews, Commentaries, and Insights. Commentaries generate thought-provoking ideas that frequently initiate fruitful debate and discussion, while Reviews provide authoritative and analytical overviews of topics of current conservation or ecological importance. The newly instituted category Insights replaces Short Communications.
