BreedingThe breeding range extends across southern Canada and the northern two-thirds of the United States, and in winter they are found across the continental United States, and into Mexico. The birds change from there winter plumage to its breeding plumage through a complete molt of all its body feathers. - Females lay 4 to 6 pale blue eggs that hatch in 12 - 14 days

Fun Facts- During courtship, one can detect the female because of its zigzag flying motion while being chased by males. - It is the state bird of New Jersey, Iowa, and Washington.

Environmental ConcernsDue to the large size of this species' global population, the American Goldfinch has an evaluation of Least Concern. This is a downgrade from Lower Risk, which was the rating in 2000. There is not any concern that the population of the American Goldfinch will face immediate decline.

American Goldfinches are numerous and their populations have been stable from1966 to 2010 according to the North American Breeding Bird Survey. The population remains stable and is not at risk of endangerment currently.

I choose this bird to its large extensive population and beautiful colors. Over the course of the research I have found, I learned many interesting facts about the American Goldfinch and birds in general. I learned the difference between birds pitch and volume depicting there emotion as well as the journey these birds take for breeding.
