Sensory structures
Birds have excellent vision and often see color better then humans do also their vision is vary detailed. They have no external ears but an acute sense of hearing. Taste and smell are not as well developed as other senses. I didn't find anything on the nervous system.

Excretory (waste) system
The birds convert nitrogenous wastes into a semi-solid paste called uric acid. Uric acid is less toxic then ammonia and requires less water to be flushed out of the body.

Importance to Humans and Enviornment.
These birds are important to humans and the environment. They eat insects that destroy crops. That is important to humans because if insects eat crops like corn, we won't have any food to eat. They also help the environment because when they eat insects, it makes sure that there aren't too many of one insect. So all they different insects all have the same amount in the environment.

Circulatory System
These birds have a double-loop circulatory system. Which means that the heart is split in half by a septum. Each half is split into halves, so there are four parts to their heart. Their heart rate is from 150-1000 beats per min. They have a high metabolism so their heart needs to beat fast to keep up with the rest of their body.

Scientific Name and Classification
Old Beak Birds are in the kingdom Animalia, phylum Cordata, class Aves, and superorder Paleognathae. The class Aves is birds and superorder Plaeognathe means old beak birds. The superorder Paleognathae is broken down to 5 orders. They are tinamous, which is the biggest order, kiwis, casuariiformes, which includes the emus, rheas, and struthioniformes, which is the ostrich. Also, most of these birds are non flying birds.

How do they get oxygen and get rid of carbon dioxide?
Birds have paired lungs and extract oxygen from the air. Even when a bird is at a high altitude and in an atmosphere with little oxygen they can still extract it efficiently enough.

Respiratory system
A birds respiratory system has to be more efficient then any other because when a bird flies they use up a lot of energy. So if they didn't have a good respiratory system they wouldn't be able to fly for vary long and they would have a hard time breathing at the altitudes they reach.

Where do they live? What are examples of their habitat and food source?
Old beak birds live in Africa. They were in Arabia, but they were hunted to extinction. Old beak birds eat seeds, shrubs, grass, and other plant manner. They also eat many insects. An interesting thing is birds swallow stones and sand to help grind up their food.

How do they support their shape? Do they have a skeleton?
Old beak birds' bones are pneumatic which means they are hollow and filled with air. Birds stand upright, but have four limbs. Two of them were adapted into wings. Birds have a small number of bones, but have more neck vertebrae they others. They also have a fused collarbone and a keel shaped sternum.

How do these animals digest their food? Do they have a complete digestive system?
Birds swallow their food whole since they do not have teeth to chew. It goes down their esophagus into their crop where large amounts of food are stored. Birds have two stomachs, an upper stomach and a lower stomach. The upper stomach is where the food is broken down. The lower stomach consists of the gizzard which is where the food is grinded up.
