How many times a year do Goldfinches molt?
They are not like other members of the finch family that molt once a year in the fall. Goldfinches are the only ones that molt two times a year. The second molt occurs in the spring when Goldfinches change from winter plumage to breeding plumage by a complete molt of feathers. They are late nesters- in June or July- when most other songbirds are finished with breeding.
A group is called a “charm”, “rush” ,”treasury”, “vein”, or “007” of goldfinches
