Birds of Prey
No mammals didn't decend from the dinosaurs, birds did. Bats came from common rodent ancestors.
Bats do, birds do not
Birds and bats
Bats are mammals while birds are avians. Bats use echolocation to navigate and hunt, while birds rely on their keen eyesight.
Both bats and birds are warm-blooded vertebrates.
Bats have fur but birds do not. Bats are mammals that give birth to live young, whereas birds give birth by way of the laying of eggs.
Bats are not birds. Bats are flying mammals. Some birds have a rudimentary echolocation capacity. These birds are the oilbirds of South America, and the cave swiftlets of Asia.
A bat bears it's young alive, does not have feathers and does not have the high metabolic rate of a bird.
No. Both are birds and their wings are a derived trait common to all birds. The wings of penguins and bats display convergent evolution.
Wings in both birds and bats are considered homologous structures. They have a similar function (flight) but different evolutionary origins – birds have wings made of feathers while bats have wings made of skin stretched between elongated finger bones.
Vampires and Vampire bats both drink blood. The only difference is that vampire bats drink animal blood. Plus vampire bats are real. The other type are fictional.
