Presence of a wing claw in White-breasted waterhen young
Wing claws are present in several species of birds that give birth to precocial young, esp. ratites. The claws help the chicks to grasp and get support from vegetation while scampering behind their parents.
This is a short note to document the presence of wing claws in the downy young of White-breasted waterhens (Amaurornis phoenicurus).
Thank you, Tatiana Petrova, for helpful information on wing claws. I really appreciate it.
