Secretary bird chicks are the cutest! They’re altricial birds, and spend about 40 days being fed by their parents, after which they tear up their own parent-delivered reptiles within the nest. After about 65-80 days, they start to fly (fledge), and are taught by both parents how to hunt soon after that. By the end of their fourth month, they generally live independently of their parents.
