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!|
