A "Field Guide"
Think of it as the same thing as land mammals versus water mammals. Marine mammals first evolved to life on land and then adapted to return to the water, but not all mammals did that. Similar thing with birds. All birds evolved from common flying ancestors, whereas flying mammals evolved from land mammals at a much later point in evolutionary history. Hope that helps.
It helps to identify specific things!
No, birds are strictly avians. Mammals that lay eggs are considered monotremes.

Birds and mammals are the two vertebrate groups that have a steady body temperature, known as endothermy. This allows them to regulate their internal body temperature independently of the external environment, which helps them thrive in a wide range of habitats.
Well, I think it helps you identify if the objects in the object are dense or not. Just sometimes things make things denser or thinner. I hope this helps and it's not TOO confusing!

By puffing out their feathers in the cold birds create a larger insulating layer of air and feathers, which helps them retain body heat. Many mammals do the same with their fur.
The inland taipan usually eats small mammals, birds, rodents, rats, mice, and anything it knows it can swallow. I hole this helps(:
Birds do not urinate like mammals do. They excrete nitrogenous waste in the form of a semisolid waste called uric acid, which is combined with their feces and expelled together. This helps birds conserve water and maintain a lighter body weight for flight.
No, burping can occur in many mammals, as well as birds and some reptiles. It is a natural process that helps release excess gas from the digestive system.
If an animal has bones, it´s a vertebrate. Fish, amphibians, reptiles, birds and mammals are vertebrates. A Jack Russell is a mammal. Hope this helps ;)
