They are not THAT closely related; bats are mammals, not birds. Both mammals and birds are vertebrate animals.
It shows the organism has same structures as its relatives.
They have a language. -APEX
The birds started to attack the humans by when the humans started to eat their bird food. Nat took a fat dump in the birds nest. Then Bill Cosby became too famous, then Nickelodeon started to promote dumb retarded teen shows, and Chris Farley tripped on a stick fell in Nat' s fat dump. Chris Farley got so mad that he planned an evil army of birds to get back at them.
it is a sign of affection and it shows that she is protected by him. congratulations, you have a couple of love birds on your hands are there puppies in the future!;)
it is un-certain that birds do chew, their food, but mammals do. But, the next best thing to a vegetarian bird that chew it's food, are the ornithops, a group of plant-eating dinosaurs which includs ceratopsids (triceratops) and the hadrosaurs (duck-billed dinosaurs) sadly like all the other dinosaurs they went extinct 65 million years ago, but it might be possible (atleast possible) if not likely that modern plant-eating birds may chew their food with annomal ridges the the sides of their beacks as they move them up and down while the ridges them selves cut up the vegetation into smaller bits, only to leave the rest grinded up by stones in their stomachs, so that the digestive juices could get back to work. So, like with mammal hervibores, as the bird's stomachs digest, the bird itsealf (the body) will be back in physycle order to their daily eating.

The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.

Not sure exactly the answer ur looking for....If you can take a male and a female of the same kind of organism and they can reproduce an offspring, then they are related. Even a donkey and a horse are related, becuz when they mate, they produce a mule. Or you can also check to see if they're in the same family, subdivision, genus, etc....If you're comparing two or more animals, you can check if they are mammals, reptiles, amphibians, birds, rodents, marsupials, etc...Even more you can check if they live in the same area, eat the same food, act a similar way.....hopes this helps u out some!
