The title of the post says it all. Here's another 1st cycle Herring with white base color to the uppertail coverts and a thinner, more pronounced, tail band than a typical
smithsonianus.
Lake County, Illinois. 10 March 2017.

What would this bird be called in Japan? |
 |
With a vegae/argentatus tail band, the undertail coverts are sparsely patterned with thin markings. |
 |
Not surprising, this isn't a chocolate-brown Smith. Like many vegae, it shows silvery 2nd generation scapulars with a faint pattern to the wing coverts. |
A different view of the uppertail (sorry for the chopped off wing)...

No known-origin American Herring has revealed such a 1st basic tail pattern, yet! |
