While most birds seem to lack much power of smell, there are some groups of birds that can locate food using their olfactory glands. Extensive research into bird senses has shown that vultures, seabirds, kiwis and parrots have well-developed olfactory glands, giving them some sense of smell and taste.

Some birds have beaks that are shredders. Their beaks are very sharp so they can tear food. An eagle flies over a stream and catches a fish. Back at its nest, the eagle uses its beak to tear the skin off the fish and pick the meat off the bones.

The beak is composed of keratin, the same tough, insoluble protein found in fingernails, hoofs, antlers and horns. A bird's bill comprises two parts. The upper portion of a bird's bill is called the maxillary rostrum, which consists of the premaxilla bone (or maxilla) and the maxillary beak (or rhinotheca).

The one thing that distinguishes birds from all other animals is feathers. Other animals are warm-blooded (mammals), lay eggs (insects and fish), or have wings (insects and bats) but only birds have feathers and all birds have feathers. Feathers are used for flight, temperature control, and attracting a mate.

In waterfowl such as ducks, geese and swans (Anatidae) the beak is much thinner and softer [7]. ... The beak will heal by a process of granulation and epithelialisation, much as with any other epidermal tissue.

The beak is a hard structure rather like a parrot's beak. However, unlike a parrot's beak, the lower beak of the colossal squid overlaps the upper beak. The beak is made of chitin and is surrounded by muscular tissue.

Ostriches, emus, cassowaries, rheas, and kiwis can't fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can't possibly lift their heavy bodies off the ground.

Our ancestors already had them. Other species that are still fully furred/feathered (penguins) have them. They predate common ancestors of mammals, showing that eyebrows have been a treat of the animal kingdom, with animals with eyes already for a long time.

Ravens hunt other animals such as mice, small birds, fish and insects but they are not birds of prey. A Raven is designed with a powerful beak that it uses to stab its prey with.

No mammal predators One reason New Zealand has so many flightless birds is that, before humans arrived about 1000 years ago, there were no land mammals that preyed on birds. Predators were other birds, such as the laughing owl, eagle, goshawk and falcon.
