The southern pied babbler (Turdoides bicolor)
This a species of bird in the Leiothrichidae family, found in dry savannah of Botswana, Namibia, South Africa, and Zimbabwe.
A behavioural description given by Wikipedia sums these birds up beautifully….
“Aggression toward fledglings is most commonly observed when the dominant pair have begun to incubate another brood. During this period, begging fledglings will be punished by parents using aggressive behaviour such as jumping on the youngster. In all cases, fledglings stop begging immediately following attack. Brood overlap results in a distinctive division of labour, with subordinate adults continuing to care for fledglings while the dominant pair concentrate their effort on the new brood. Owing to the extended period of post-fledging care in this species, this can result in dependent young from multiple broods being raised simultaneously.”
Now is this not a lesson we could learn from them,???? Kids get out of hand … “JUMP ON THEM !!!!” ….
