The goldfinches have started coming back to the yard after being gone for several weeks.
They are taking advantage of the flowers finishing their blooms.
This is monarda or bee balm.
Goldfinches are among the strictest vegetarians in the bird world, selecting an entirely vegetable diet and only inadvertently swallowing an occasional insect.
As of May 2007, the oldest known American Goldfinch was 10 years 5 months old.
