The Goldfinches are swarming to the sunflowers as the seeds ripen
Immature birds are changing to adult plumage and adults are molting making it difficult to separate the immature from the adults.
This male perched on an okra plant exhibits the early stage of the molt. Soon he will be sporting his new winter plumage which is little different than the female. Just one week ago all of the males I observed were brilliant but during this mornings shoot all were molting with some more progressed than others.
