摘要

巴西红宝石(Heliodoxa rubricauda)是大西洋森林特有的一种森林蜂鸟。它属于安第斯山脉的一种鸟类,腿健壮有力,适应以高处植物的花序为食,受强风影响。它发生在巴西东北部到南部的斜坡、山脉和山上,有鲜为人知的在瀑布和森林溪流中洗澡的行为。根据在圣保罗州进行的五次实地观察,以及在线照片平台上的记录,我们得出结论:红花鸟(H. rubricauda)是巴西唯一一种通过落在森林瀑布的岩石上洗澡的蜂鸟,这些瀑布有中强水流。这种行为是由于这种物种从其进化谱系中继承了强壮的腿,在大西洋森林中,这些腿用于觅食、防御和洗澡。我们假设这种行为比其他现有的行为更有效地保持身体卫生,因为它允许更多的水通过身体,从而消除食物和寄生虫的痕迹,此外还减少了被捕食的风险。

A novel mode of bathing behavior of hummingbirds recorded in the Brazilian ruby Heliodoxa rubricauda and allies (Aves: Trochilidae)

The Brazilian ruby, Heliodoxa rubricauda, is a forest species of hummingbird endemic to the Atlantic Forest. It belongs to an Andean clade of birds with robust and strong legs and adapted to feed on inflorescences of plants from high regions and influenced by strong winds. It occurs from northeastern to southern Brazil on slopes, sierras, and mountains and has the little-known behavior of bathing in waterfalls and forest streams. Based on five field observations made in the state of São Paulo, and records available from online photo platforms, we concluded that H. rubricauda is the only species of hummingbird in Brazil that bathes by settling on rocks of forest waterfalls with medium to strong currents. This behavior is made possible by the robust and strong legs the species inherited from its evolutionary lineage, which, in the Atlantic Forest, are used for feeding, defense, and bathing. We hypothesize that this behavior is more efficient for body hygiene than other existing behaviors because it allows a greater amount of water to pass over the body, thereby eliminating traces of food and parasites, in addition to reducing risks of predation.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
