Bird Brains And Nerves
Like all animals birds need a control center and a set of communication channels to ensure that there system runs smoothly. As in most more complicated animals this is usually called a brain and a nervous system.
Vibations And Touch In Birds
Birds have contact and touch sensors on various parts of their bodies. These include their feet, bills and tongues ( i.e Woodpeckers). This relates to the fact that it is these parts of their bodies which most often come into contact with the rest of the world. In some birds the tactile sensors are particularly well developed in the bills allowing them to feed mostly by probing and feeling for prey, this is most evident in waders. Birds also have special small feathers called bristles which are ...
About Bird Feathers
Feathers are one of the most prominent features of a bird's anatomy, and they are unique to birds. Every bird has feathers and everything that has feathers is a bird. Feathers perform a number of functions for a bird. Firstly, they provide insulation, this is very important in a warm blooded animal (body temperature of most birds is maintained at around 40C). It is believed by most scientists that this insulating effect was the primary force driving the evolution of feathers, i.e. ancestral bird...
The Avian Eye And Vision
A bird's eye is very similar in its basic structure to a human eye. Though with certain modifications and differences. The eyes make up a much larger percentage of the weight of the head in birds than in man, i.e. 15% for a common Starling but only 1% for man. This is partly because a bird's eyes are larger relative to its skull than a human's and partly because the skull is lighter, i.e. no heavy jaw bone and teeth.
