Abstract

Facial bristles are present in many avian species, although their morphology and function are still not well understood. Previous studies have suggested that rictal bristles are tactile and may play a role in nocturnal foraging, although how they develop and are used is unclear. We study here the facial bristles of the tawny frogmouth (Podargus strigoides). We describe the development of rictal bristles, alongside other developmental milestones, such as plumage and eye-opening. We note four clear stages of plumage and eye-opening and three stages of rictal bristle emergence. Chicks were born without facial bristles, and rictal bristles emerged after the eyes matured. They were fully developed only after the chick had fledged and engaged in independent feeding. This supports the suggestion that rictal bristles may play a role in independent foraging and feeding.

茶色蛙嘴（Podargus strigoides）面部刚毛的发育

面部刚毛存在于许多鸟类物种中，尽管它们的形态和功能还没有被很好地理解。先前的研究表明，喙毛具有触觉，可能在夜间觅食中发挥作用，尽管它们是如何发育和使用的尚不清楚。我们在这里研究茶色蛙嘴（Podargus strigoides）的面部刚毛。我们描述了临界刚毛的发展，以及其他发展里程碑，如羽毛和睁眼。我们注意到羽毛和睁眼的四个清晰阶段和毛毛出现的三个阶段。雏鸡出生时没有面部刚毛，眼睛成熟后出现临界刚毛。只有在雏鸟羽翼丰满并开始独立进食后，它们才能完全发育。这支持了临界刚毛可能在独立觅食和摄食中发挥作用的建议。

期刊介绍： Developmental Psychobiology is a peer-reviewed journal that publishes original research papers from the disciplines of psychology, biology, neuroscience, and medicine that contribute to an understanding of behavior development. Research that focuses on development in the embryo/fetus, neonate, juvenile, or adult animal and multidisciplinary research that relates behavioral development to anatomy, physiology, biochemistry, genetics, or evolution is appropriate. The journal represents a broad phylogenetic perspective on behavior development by publishing studies of invertebrates, fish, birds, humans, and other animals. The journal publishes experimental and descriptive studies whether carried out in the laboratory or field. The journal also publishes review articles and theoretical papers that make important conceptual contributions. Special dedicated issues of Developmental Psychobiology , consisting of invited papers on a topic of general interest, may be arranged with the Editor-in-Chief. Developmental Psychobiology also publishes Letters to the Editor, which discuss issues of general interest or material published in the journal. Letters discussing published material may correct errors, provide clarification, or offer a different point of view. Authors should consult the editors on the preparation of these contributions.
