The division of the races of canaries canary in color, and in a corner and stance is purely artificial. Not only are called canaries of canto singing, not just the color that have color and are not just the shape and posture that behave in a certain way in the perch.

It is, therefore, a division that serves the interests of Aviculture but is far from being scientific.

This goes even further since, in the color of canaries divide lipochrome and melanin is also artificial and baseless science: the wild duck has its own melanin pigments and pigments lipochrome.

Either way, the truth is that, worldwide, who speaks in the Canaries position and posture is understood between the creators and who speaks in canaries Color or corner as well. This is because the various breeds of canaries corner is required to have a specific way of singing and that of color have certain characteristics.

Thus, the canary in a position and provides that its shape is specific and that its position on the perch is also special.

The problem of the form requires major studies, since nothing is known of relationship between the various body parts of birds. In nature there are birds long neck and short neck, like birds of wide body and slender body. Not so in canaries, since, in a general, birds have a wide body head and thick neck, while the canaries have elongated narrow head and long neck. Leave this topic to other articles and Let us focus on the problem of postures.

The way the canary is teetering on its perch poses problems as deep that you can not expose them in one article. Variables are so we have to eliminate some to put the problem so suitable. Therefore, I sought the assistance of an engineer biologist.

The big question is: what makes a bird to put more vertical or more horizontal perch? We all know that the parakeet Australian remains almost vertical in the perch and the canary Harz sings almost in a horizontal position. As we said, many variables are are in conflict: skeleton, muscles, body shape of the bird, among others. There is also an important factor to take online

account: the habit or training. In fact, while farmers canaries of posture more upright, as is the case of the Yorkshire train birds placing cards around the cage for the bird to stretch to peeking out, the creators of the Harz canaries in place cards roof of the cage for the bird to put as horizontal as possible, with the intention to deliver bass notes, the most appreciated.

The study of the position of the canaries in the perch is the observation of several factors and can be done through a number of ways. So can promote the study through the skeleton of different races, see the position of other birds in nature or, more sophisticated study model on the computer.

For the first study assembled skeletons Yorkshires and the Canaries der color to studying its position on the perch.

In order to establish a computer program, promoting implementation of a biological model, simplified in a first approach study of the position of the Canaries, the number and focus attention on skeleton. We know that birds of the shuttle high tend to vertical. Let us briefly review anatomical:

The skeleton of the lower limb and canary birds in general is not constituted as the mammals. What seems to be the leg (which appears featherless) is still part of the foot, the first two bones of the foot are merged into a single bone is called cinnamon.

Thus, in birds like the canary, there are 3 fingers before and after 1; followed by the cinnamon, then the leg, then the thigh that articulates the hip bones. Thus, we consider an angle between the fingers and cinnamon, one between the shuttle and the leg, the other between the leg and thigh, and Finally, the articulation between the thigh and the body. This whole interferes with the position of the bird or by angles. Whether the length of segments.

Of all these elements, which seems more important study is length of the shuttle, as we know, varies according to race. Thus model we study has two variants: the length of the shuttle and body shape.

This study, which looks very theoretical, is of great importance for claim form and position of various breeds of canaries and Arlequim is undoubtedly an ideal bird for this study, because you want it

a bird of cinnamon and high erect, more in keeping with the old canaries created by the Portuguese. This form, associated spares gives ave an unparalleled arrogance and vivacity.

While these studies are done, we can advise farmers is that birds select high cinnamon which, without constituting a security of good examples already provides an important element in the creations future. In time, the magazine Arlequim provide input on these

experiences.
