Obedience training usually refers to the training of a dog and the term is most commonly used in that context. Obedience training ranges from very basic training, such as teaching the dog to reliably respond to basic commands such as "sit," "down," "come," and "stay," to high level competition within clubs such as the American Kennel Club, United Kennel Club, and the Canadian Kennel Club , where additional commands, accuracy and performance are scored and judged.

Obedience implies compliance with the direction or command given by the handler. For a dog to be considered obedient rather than simply trained in obedience, it must respond reliably each time its handler gives a command.

Training a dog in obedience can be an ongoing and lengthy process depending on the dog, the methods used, and the skill and understanding of both the trainer and the handler. The level of obedience the handler wishes to achieve with the dog is also a major factor in the time involved, as is the commitment to training by the handler.

Obedience training is often a prerequisite for or component of other training.

Optimum nutrition can be achieved with many different diets.  However it is not easy and understanding some basic  principles of the pro and cons of each food item as it relates  to vitamins, minerals, proteins, fat is important when trying to  make up a mixture of foods. Wild animals and birds are  shown by their parents the right combination of sometimes  very limited types of foods to meet their requirements for  flight, growth, reproduction and living!

These wild food items have been selected through thousands of years of evolution. In captivity they are under different conditions and eating different foods and we expect them to select the best combination immediately.

But it is not necessarily better to feed what birds eat in the wild to those in captivity. Many plants in the wild contain secondary plant compounds or are very low in many essential nutrients.
