It differs in the way mammals and them birds. Mammals feed from their breasts. On the other hand birds go outside the nest to catch like slugs,worms,snails.
searching for food, chewing it, throwing it up in the young birds mouths, and pushing them out of the nest when they believe it is time for them to fly.
When the babies are born both the male and female will feed the babies. The birds aggressively defend their nests and surrounding areas against other birds and animals.
Modern reptiles provide nothing for their young, they simply lay the eggs and leave. However there is evidence showing that some dinosaurs provided care for their young in large nests similar to what modern birds do.
Reptiles and fish lay eggs and can't sit in one place waiting for them to hatch like birds
like many other birds and other species, they take care of their young... and they also protect their young from predators
