Oriental white-eye nesting
This pair of extremely capable parent brought up not 1 not 2 not 3 but 4 little ones in a tiny little nest. Not all fledged at the same time. The parents never leave any of their chick behind. They continue to feed the last remaining one until he was ready to leave the nest 2 days later than its siblings.
Occasionally, the chicks would instinctively stick their butt up for their parent to clear the poo as presented here.
So..if you're born as a white-eye, you'll be performing that later in life unless you employ someone else to do the job or choose not to have kids.
