Abstract

Previous studies have shown that thyroxin injections cause definite color changes in the plumage of the male sparrow. Attempts have been made to induce hyperthyroidism by stimulating the thyroids with injections of thyrotropic hormone extracted from sheep anterior pituitary. Microscopic studies of the thyroid glands and measurement of the metabolic rate indicate that a hyperthyroid condition has been produced. However, no modifications in plumage have been noted following varying doses of thyrotropic hormone or combined injections of thyroxin and thyrotropic hormone.
