Abstract

Abstract. Interspecific feeding is an uncommon behaviour where an individual of one species feeds individuals (mostly offspring) of another species. Observations have been made in many avian species but causes of this behaviour remain unknown and no hypothesis was proposed to fully explain its occurrence. In this review, I collected observations of interspecific feeding in birds reported during the last 40 years and compiled a comprehensive dataset based on all published reports of interspecific feeding. It consists of 186 cases observed in 107 species worldwide and summarizes the information on involved species, their age, sex, and possible causes of this misdirected parental care. Additionally, I report a case of Great Spotted Woodpeckers' Dendrocopos major young fed by Eurasian Nuthatches Sitta europaea. Observations of interspecific feeding are highly skewed in favour of North American and European species, probably due to historical (long research and ornithology traditions) and language issues (publishing in English). Interspecific feeding does not seem to be related to nest type but is mostly associated with males allured by loud calls of nestlings from nearby allospecific nests. However, most of the observations remain only anecdotic and an empirical research that would try to find plausible explanations of the evolutionary advantages of this behaviour still remains to be carried out.

鸟类种间摄食:简要概述

摘要种间摄食是一种罕见的行为，即一个物种的个体摄食另一个物种的个体(主要是后代)。人们对许多鸟类进行了观察，但这种行为的原因尚不清楚，也没有提出任何假设来充分解释这种行为的发生。在这篇综述中，我收集了近40年来报道的鸟类种间摄食的观察结果，并在所有已发表的种间摄食报告的基础上编制了一个综合数据集。它包括在全球107个物种中观察到的186例病例，并总结了有关物种的信息，它们的年龄，性别以及这种错误的亲代照顾的可能原因。此外，我报告了一个由欧亚Nuthatches Sitta europaea喂养的大斑点啄木鸟的主要幼崽的案例。种间取食的观察结果高度偏向于北美和欧洲的物种，这可能是由于历史(长期的研究和鸟类学传统)和语言问题(以英语出版)。种间取食似乎与巢型无关，但主要与雄性被附近同种巢的雏鸟的大声叫声所吸引有关。然而，大多数观察结果仍然只是轶事，一项试图找到这种行为的进化优势的合理解释的实证研究仍有待开展。
