Deamination of amino acids in mammals yields amino groups that are converted to which is(are) excreted, and which is(are) converted to one of the reactants of glycolysis or the citric acid cycle.

Deamination of amino acids in mammals yields amino groups that are converted to ammonia, which is excreted, and the remaining carbon skeleton, which is converted to one of the reactants of glycolysis or the citric acid cycle. Ammonia, formed from the amino group is toxic for the organism so it needs to be converted into urea and excreted by the kidneys.
The remaining carbon skeleton is converted to glucose,  ketone bodies or acetyl CoA.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
