Foraging strategies in gentoo penguins (Pygoscelis papua) have been well studied (e.g. Croxall et al. 1988, Robinson & Hindell 1996, Lescroël et al. 2004, Takahashi et al. 2008, Xavier et al. 2017). The general consensus is this largest member of the three pygoscelid penguins displays both nearshore benthic and pelagic foraging tactics to consume combinations of crustaceans and fish. In a recent study, Carpenter-Kling et al. (2017) reported that gentoos at sub-Antarctic Marion Island displayed a novel foraging strategy that consisted of alternating typical lengthy foraging trips with much shorter nearshore afternoon trips. They suggest the latter foraging behaviour may be a response to suboptimal feeding conditions caused by local environmental change. This novel discovery reinforces the fact that, despite considerable study, not all foraging tactics in penguins have been documented. In this paper, we describe what we believe to be, yet another undocumented foraging tactic employed by gentoos.

巴布亚企鹅在大型海藻筏上的潮间带觅食

gentoo企鹅的觅食策略（巴布亚果蝇) 已得到充分研究（例如 Croxall等。1988 年，罗宾逊和欣德尔 1996 年，Lescroël等。2004年，高桥等。2008，泽维尔等。2017）。普遍的共识是，这三种 pygoscelid 企鹅中最大的成员展示了近岸底栖和远洋觅食策略，以消耗甲壳类动物和鱼类的组合。在最近的一项研究中，Carpenter-Kling等。（2017 年）报道，亚南极马里恩岛的巴布亚猴展示了一种新颖的觅食策略，包括交替进行典型的漫长觅食旅行和更短的近岸下午旅行。他们认为后一种觅食行为可能是对当地环境变化引起的次优摄食条件的反应。这一新发现强化了这样一个事实，即尽管进行了大量研究，但并非所有企鹅的觅食策略都被记录在案。在本文中，我们描述了我们认为是 gentoos 采用的另一种无证觅食策略。
