Fish do not take care of their young. Young fish hatch and swim away. Some become food for larger fish ( feeder fish) and others escape to grow up.
Birds and Fish!
Both birds and mammals care for their young.
The length of time parent birds care for their young varies depending on the species. Generally, parent birds will care for their young until they are able to fend for themselves and become independent. This can range from a few weeks to several months.
All birds lay eggs and most of them take care of their young. However, a few mammals and amphibians fit those two criteria, as well. I am unaware of any living reptiles that fit that criteria, although some guard their nests until their young hatch, but many if not most dinosaurs raised their young, and they all laid eggs.
Yes , most of endothermic animals are birds and mammals and they care for their young ones .
No, birds do a pretty good job of taking care of their young!
