To witness how animals take good care of each other is absolutely mind blowing.
A couple of European Goldfinch (Carduelis carduelis) taking care of their nest. During the hatching, the female never leave the eggs, while the male keeps watch not far away and bring her some food every now and then.
In the case of White Wagtail (Motacilla alba), both parents incubate the eggs, which hatch after 12 days. At a later time, they feed the chicks for at least two weeks, until they fledge, and then for another week after fledging.
