Our Alaskan Yellow Wagtail is a form of the east Siberian (B. f. leuco-striatus) bird and there is a third form {B. J. flams) in Europe. American Dipper (Cinclus mexicanus unicolor, Fig. 5).—The male andfemale Dipper are alike in color, and their winter plumage differs from theirsummer plumage (Fig. 5) only in having the underparts and ends of the innerwing-quills margined with whitish. The nestling Dipper is more or less buffybelow, especially on the abdomen, while the crown is practically as gray as theback. After the postjuvenal molt through which it passes into first winter plu-mage, it more nearly resembles the adult, but the head is grayer and the throatwhiter. Representative forms of the Dipper are found in Mexico andjnCosta LOUISIANA WATER-THRUSHPhotographed by A. A. Allen, Ithaca, N. Y.
