Gold finch : Behavior, Lifespan and Unknown Facts

Gold finch is the most common and welcomed bird in our back yards. Their sweet personality and vibrant colors make them so unique, even they are called as wild Canaries for their eye catchy plumage. These birds are classified as song birds due to their distinctive chirping. Here are some interesting facts about them.

1. Gold finch is only of 3 types, the American Lesser & Lawrence Gold finches are found in South East America, whereas the European Goldfinches are found across the Atlantic in Europe, they were also introduced in Australia and New Zealand 100 years ago.

2. Male and female goldfinches look pretty much the same, although males have a longer beak. Juveniles however, are much dull in color. They are mainly brown with some yellow markings on the wings. And they don’t have the distinctive red face, which they gain in adulthood.

9. These finches can’t tolerate sub zero temperatures in the winter. Study on these banded birds have revealed that some American Goldfinches do migrate more than 1,000 miles from Ontario to Louisiana.

10. Gold finch can feed upside down. Often they are observed hanging upside down from the top of a big sunflower, picking out the seeds from below. And the ability to pose upside down helps these birds as they sway on the fragile seed of grasses and other plants they love.

11. Generally these birds can live for 4-7 years depending on food supply and predators. In 2007, the oldest one ever recaptured in the wild was an American Goldfinch of 10 years and 5 months old.

12. The American Goldfinch is the only finch species that molt twice a year. First time in spring when the males get their bright yellow feathers, and the second is at the end of summer when the darker feathers appear.

13. Their names may sound similar, but the European and American Goldfinches are not closely related. As classified in separate genera, the coloring are also different making it easy to identify them separately.

14. Goldfinches can be found in a number of religious artworks from the Italian Renaissance. Because it eats thistles, the bird was associated with Christ’s crown of thorns and was referred to as a “savior” bird.

15. Females are dominant over males in the summer and appear to be subservient to them in the winter.

16. They use a 4 syllable call when they are ready to take flight. If you listen closely, it sounds like the birds are saying “po-ta-to-chip”. Both males and females use that call identically.
