Discovering the American Goldfinch and their habits.
Discovering the American Goldfinch
The American Goldfinch, with its vibrant yellow plumage and cheerful song, is a true gem of our backyards, especially here in Southern Ontario. These small, lively birds bring a splash of sunshine to any garden, making them a favourite among birdwatchers and nature lovers alike. But there's more to these little birds than just their striking appearance. Let’s dive into the world of the American Goldfinch, exploring their habitat, diet, nesting habits, and more.
A Bright and Beautiful Bird
One of the most distinctive features of the American Goldfinch is its brilliant yellow feathers, which are most vivid in males during the breeding season. This bright coloration is often highlighted by contrasting black wings, a black forehead, and white markings. Females and non-breeding males, while not as brightly coloured, still sport a charming, softer yellow or olive hue, which helps them blend into their surroundings outside the breeding season.
Preferred Habitat
American Goldfinches are commonly found in open areas such as fields, meadows, and gardens, where there is an abundance of seeds. They are especially fond of areas with thistles and sunflowers, which provide both food and nesting materials. These adaptable birds are also regular visitors to backyard feeders, making them a common sight in residential areas with the right habitat.
Diet: Seeds, Seeds, and More Seeds
Unlike many other birds that rely heavily on insects, the American Goldfinch is primarily a seed-eater. In fact, they are one of the most exclusively vegetarian birds, feeding almost entirely on seeds from plants like dandelions, sunflowers, and thistles. They have a particular fondness for nyjer (thistle) seeds, which are often used in specialized finch feeders. If you want to attract more Goldfinches to your yard, providing a steady supply of nyjer seeds is a sure way to do it.
Tip for New Feeders: Only fill your nyjer feeders just past the first port. Once you see the food line go down, or actual birds eating at the feeder, THEN go ahead and fill to the top. The space in the feeder tends to peak their curiosity faster. Brand new full feeders in the yard tend to be ignored. A daily shake to aerate the seed helps keep it fresher longer especially in damp weather conditions.
Nesting Habits
American Goldfinches have a unique approach to nesting. Unlike many other birds that begin nesting in early spring, Goldfinches delay their nesting until late summer. This timing coincides with the peak abundance of seeds from plants like thistles, which provide both food and nesting material. The female Goldfinch is the primary builder of the nest, creating a small, compact cup of plant fibers, lined with soft materials like thistle down.
These nests are typically placed in the forks of small trees or shrubs, often several feet off the ground. The female lays 4 to 6 pale blue eggs, which she incubates for about two weeks. After hatching, the chicks are fed a diet of regurgitated seeds by both parents. The late nesting period of Goldfinches means that their young are raised during the warmest months when food is most plentiful. Late nesting also means less chance of Cowbirds parasitically leaving eggs behind in the goldfinch’s nest. Which is good for both birds - Cowbird nestlings cannot survive on a diet of seeds, and cowbird babies are a waste of energy for the Goldfinch’s.
A Year-Round Resident
In Southern Ontario, American Goldfinches are year-round residents, though their appearance changes with the seasons. During winter, their bright yellow plumage molts into a more subdued brownish-olive tone, helping them blend into the drab winter landscape. Despite this change, their distinctive flight pattern—a series of undulating dips and rises—makes them easy to identify even from a distance.
Bringing Goldfinches to Your Yard
To attract American Goldfinches to your yard, consider planting native plants that produce the seeds they love, such as sunflowers, asters, and coneflowers. Providing a reliable source of fresh water, such as a bird bath, will also make your yard more appealing. And of course, a well-maintained feeder filled with nyjer seeds, Wild Finch mix or a Nyjer-Sunflower chip mix is a surefire way to bring these beautiful birds closer to your home.
The American Goldfinch is more than just a pretty bird; it’s a fascinating species with unique habits and preferences that make it a joy to observe. By understanding their needs and creating a welcoming environment, you can enjoy the company of these delightful birds year-round. So, keep your feeders stocked, plant some seed-rich flowers, and enjoy the bright flash of yellow that Goldfinches bring to your backyard.
