Flight

The fact that birds fly is one of the most amazing things about them. The sight of crows or ravens playing in the wind, of seagulls gliding effortlessly along seashore, kingfishers catching fish, or of buzzards soaring silently about the countryside is always inspiring. Birds are the ultimate flying machines, though insects have been doing it for longer and in many cases are more versatile; their small size makes the physics of it much easier. Birds fly far better than any machinery mankind has yet made and like our machines they use their wings and tails in a variety of ways to achieve their expertise.

Bird flight is dependent on the shape of the birds wings and the way they use them. Generally, bird flight can be divided into two modes of functioning, i.e. gliding or soaring flight, and flapping or powered flight.

Search EcoPort
This search facility allows you to search EcoPort directly without having to navigate the more detailed EcoPort menu. EcoPort contains record structures for all birds of the world, and can be searched on scientific or common name in any language (provided it has already been entered). As the bird entities in this knowledge system are relatively new, most records will consist of the scientific name, some taxonomic information, and at least one common name only. This facility can be used to search for any entity type in EcoPort e.g. plants, insects, fungi, bacteria, mammals, birds, and spiders.
