There was water down there.

American Goldfinch, Dec 27, 2020, Rondeau Provincial Park, Ontario, Canada.


The blue jays found it and opened up the crevasse down to the water in the little stream in our yard.
All the other birds appreciated the jays efforts.
Spinus tristis
When Brown-headed Cowbirds lay eggs in an American Goldfinch nest, the cowbird egg may hatch but the nestling seldom survives longer than three days. The cowbird chick simply can’t survive on the all-seed diet that goldfinches feed their young.
The oldest known American Goldfinch was 10 years 9 months old when it was recaptured and rereleased during a banding operation in Maryland.
