Finch invasion!

A charm of finches chatting at the feeders is a welcome sight!

No, it’s not your imagination. There are definitely more finches out there than normal. This is turning out to be one of the best years for bird watchers! Customers have been reporting an increase in the numbers of American Goldfinches as well as several other bird “invaders”.

Canada’s natural seed crops were horrible this year and lots of birds that usually like to winter further north have ventured south to mid-Michigan to find food.

Our bright yellow and black goldfinches are now sporting their duller olive green winter wardrobe. Goldfinches are found year-round at Michigan bird feeders, but some of their northern goldfinch relatives have joined our flocks to create a big-time show at the bird feeders.

I love the happy, warm, song of the goldfinches especially in the cold months. I love the huge flocks of finches that flutter down from the tops of trees as they take their turn at the feeder. I love that I can hang the feeder anywhere because squirrels and other animals don't bother with Nyjer Thistle. And once you understand the goldfinches' needs, they are easy to please and very pleasing to watch.

Fun Facts on Goldfinches:
- Unlike many birds, goldfinches molt their body feathers twice a year, bright, attractive yellow feathers in the spring before breeding and much denser olive brown feathers after nesting in the fall.
- The color of the legs, feet and bill of the American Goldfinch change with each feather molt too. In winter plumage, their legs, feet and bill are dark grayish brown. In breeding plumage they change to a buffy yellow orange color.
- To stay warm on a cold winter’s night, American Goldfinches have been known to burrow under the snow to form a cozy sleeping cavity. They will also roost together in coniferous trees or roosting pockets.
- Goldfinches are sometimes referred to as wild canaries, but are actually in the finch family as their name suggests.
- American Goldfinches are common feeder visitors and prefer Nyjer® (thistle) and sunflower seeds.
- Due to their almost exclusive diet of seeds, the goldfinches drink frequently and will stay close to reliable sources of water.
- The genus name, Caruelis, is from the Latin word carduus, which means “thistle.”
- Residential flocks of American Goldfinches roam widely during the winter and have been recorded moving over 4 miles between multiple feeding stations in a single day.
- Female American Goldfinches are dominant over males in the summer and appear to be subservient to them in the winter. See if you call tell a difference at your feeders.
