American Goldfinches, Why Do They
August 29, 2016
(Green Cotton Bolls.)
We have had our share of rain this August.
The thing is, it has rained inches at a time, not so much as a timely rain.
We will take it.
Daylight continues to grow shorter. more than an hour of daylight on each side.
Still, we still have plenty of summer to enjoy and flowers to enjoy and care for.
Not to mention vegetable gardens to harvest, and farmers markets to visit.
There is joy in caring for gardens and watching them grow.
Reaping the rewards of your labor.
And for most gardeners, sharing when you have too many veggies or a fresh bouquet.
This always brings joy to me.
Most years I will try to grow something new or different.
Something that catches my eye.
Strawberry spinach one year.
The challenge of growing cotton in Michigan another.
I still grow a cotton plant or two just for the challenge and conversation piece it makes.
I learn some history along the way.
This year, it is
'Pumpkin On A Stick'.
An Ornamental Eggplant.
A member of the night shade family.
So far things are growing quite well.
They look and grow like eggplant, on the most part.
There are a few spurs on the leaves to watch out for.
A few insect holes in some leaves.
A bout with spider mites (under control)
They do indeed look like little pumpkins.
The jury is out until I see how they do for Karen's fall decorating.
Pretty cool looking so far.
Sounds I enjoy so much this time of year and through September, are the many call and cries from the current batch of fledged American Goldfinches.
It's a bit wordy, but worth it.
American Goldfinch (Carduelis tristis).
I write on this topic every couple of years, and I will until people get it right.
Maybe I need to do it more often to pound the message home.
Many experts want you to believe that American goldfinches wait to nest so they have thistle down to line their nest with.
Maybe there is something romantic about that whole idea.
“Waiting for thistle down to build a nest.”
Let's Get Real Folks..........
This couldn't be farther from the truth, and I don't understand why this is always brought up as the answer or reason.
(I've even E-mailed a couple of these authors, experts, and their publications to explain this to me, but I never had a response back.)
Its all about food.
Yes, some species of birds do indeed require certain habitats.
Kirkland's Warbler require Jack Pine scrub to nest in.
No Jack Pine Scrub and they simply don't breed and nest.
Still, if there isn't a food source, the best field of scrub is useless.
Common loons require a good sized, and quiet body of water to raise a family and for take-offs and landings.
However, without a supply of food, Lake Superior would be rendered useless.
The same goes for all of our birds.
The basics of life.
Food, water, shelter.
Shelter doesn't matter much.
If you are still here, I'll attempt to explain this whole thing to you and you can decide.
Now remember, I'm a Naturalist.
I think like a 'Naturalist' (sometimes).
Often, I see things differently .
I'm also a 'Michigan Certified Nurseryman' which means, I just might, or I should know a thing or two about plants and possibly weeds.
(I don't know everything, but I am required to know a few things.)
Things that 'Ornithologists' may not be on top of.
Here is a Fact or Two:
A vast majority of the thistle weeds that find there way into your gardens and grow along roadsides and fields are introduced and invasive species.
Yes, even 'Canadian Thistle' (Cirsium arvense) pictured, is an introduced species from Europe and on the invasive plant species list.
It is believed that seeds were in grain supplies and brought to life sometime in the 17th or 18th century.
(Most species of thistle came over with European settlers.)
Bull Thistle (Cirsium vulgare), pictured below.
Bull thistle is often used in photos and paintings with goldfinches.
Bull thistle is a widespread biennial thistle originally from Europe and Asia, but now introduced throughout North America.
Although it is intimidating in appearance and can sometimes form large infestations, this thistle is not as challenging to control as many others and is mainly a problem in hay fields and pastures.
Also found along roadsides.
Whether in plant form or seed mixed with crop seed, it is now here to stay.
I digress...... (Bull Thistle in bloom.)
Now if I remember my history, possibly 400 or so years have passed since some of these weeds were possibly introduced along the eastern coast of North America.
That means that these noxious thistle plants have been around for maybe 200 years or less for many locations.
Maybe 100 years in the western regions of North America.
I believe in creation, but that isn't even a blink of an eye, even in evolution terms.
So, what did American goldfinches do, or use before thistle plants came along, if it is all about thistle down that is?
Besides, are there actually enough thistle plants scattered about to line all the goldfinch nests?
What about suburbia where thistle plants may be rare?
If plant down is an issue here, why not nest in the spring when there is plenty of down.
Anyone that lives near a female Cottonwood tree, knows there is more than enough plant down in the spring to line all the nests in your county or region you live.
Wild willows provide down in the spring and countless native plants and weeds provide down as well throughout the season.
So my question is this....
How can plant down be the reason these birds nest so late in the season?
And why do so many promote this belief?
Plant down isn't the answer for late nesting at all.
It's all about food, period.
American goldfinches are 99.9 percent seed eating birds.
Virtually everything they eat is some kind of seed.
Even newly hatched Goldies are fed a regurgitated mix of seeds.
Are you with me?????
Now then ....
What time of year do most plants go to seed?
How often do you see goldfinches gleaning from your sunflower heads or your coneflowers?
Goldfinches enjoy Liatris, Coreopsis, Rudbeckia, Gaillardia, etc. as well.
Late summer offers seeds from Goldenrod, Asters and a host of plants and weeds.
So many of our plants and weeds go to seed in mid to late summer, and into fall.
Seed eating birds .................................
Most plants go to seed in late summer.
Makes sense that our Creator would dovetail the two.
So now I have scores of seed eating, fledged goldfinches coming to my yard and in the fields (other critters preparing for winter too) and Nature's table is set for the bountiful feast.
If Goldies fed on insects, berries and other stuff like most bird species, they would have different nesting seasons.
But they don't.............
They are seed eating birds.
The same holds true for Cedar waxwings that are heavy berry feeding birds.
Waxwings nest later than most, as they require berries for the main part of their diet.
Strictly insect eating birds migrate long distances for the bugs.
They also leave early to follow the insect trail back to winter homes.
The same goes for hummers that feed on nectar and small insects.
They follow the food sources.
Supply and demand.
I Love Creation, it is so amazing how God put it all together, without missing a beat.
It is silly we we try to explain things any other way.
While most American Goldfinches have one clutch, there are some years and in some regions they will have a second clutch.
The last couple of years I've noticed well into fall several fledglings and that sound of feed me.
A nice way to extend the season for us, don't you think?
There you have it...........
Why do American goldfinches nest so late?
Thistle down for nests, or seed for seed eating birds.
You know where I stand on this topic, but your choice is up to you.
As habitat continues to shrink, your feeders and wildlife gardens play a key roll.
You can offer a wide variety of native plants that offer seed and nesting materials.
While natural habitats continue to shrink, Gardening For Wildlife plays a vital roll.
No matter where you live.
Well,, it is time to fly for now.
Before I go, here is your positive thought for the week.
"Confidence on the outside
begins by living with integrity on the inside".
Why is integrity so important?
Read on my friend.
"The integrity of the upright guides them,
but the unfaithful are destroyed by their duplicity".
An old Cherokee is teaching his grandson about life.
“A fight is going on inside me,” he said to the boy.
“It is a terrible fight and it is between two wolves.
“The other is good – he is joy, peace, love, hope,
The grandson thought about it for a minute
The old Cherokee simply replied, “The one you feed.”
Your friend indeed,
Better yet, have them sign up so they can receive their own letters.
