Circling Back Around

This time they flew past me coming from the other direction and closer. This time I noticed the green speculum patch on several of the wings. The blue part of the wings is called the coverts but in addition, many ducks have a patch called the speculum with a bright iridescent color, in their case, it is green. Look close, can you see it? It is under the blue and you can only see it on the top side of the extended wing.
