No, they have endoskeletons like any other bird (and you, too).
No, all birds are vertebrates, meaning that they have an internal skeleton just like you and me.
An exoskeleton is one that is outside the body, like a lobster's. Barn owls do not have them. They have their bones inside, like all vertebrates.
No, a crow does not have an exoskeleton. Crows, like all birds, have an endoskeleton, which is an internal skeleton made of bones. Exoskeletons are found in some invertebrates, such as insects and crustaceans, where the skeleton is on the outside of the body. Birds have feathers and other adaptations that distinguish them from animals with exoskeletons.
Presence of chitin on the outer surface of the insect body
Yes, like all birds they do have bones.
Moths are arthropods because they have jointed legs and a chitin exoskeleton and birds are chordata because they have a backbone and nervous system.
Lady bugs (lady birds, lady beetles), like all other insects have an exoskeleton meaning the skeleton is on the outside.
Insects, arachnids, and crustaceans have an exoskeleton, which is a hard outer shell for protection and support. Vertebrates, such as mammals, birds, reptiles, amphibians, and fish, have an endoskeleton made up of bones and cartilage inside their bodies.
Birds detect the presence of a hawk through their keen eyesight and acute hearing. They also rely on alarm calls from other birds to alert them of potential danger.
Usually no.
