their coverts a dull reddish brown indistinctly barred with buff 
bordered with dull black, the inner members black terniinally 
edged with rich buff. Below dull gray on throat, breast and sides, 
the feathers with white shaft-streaks, the abdomen dull white and 
the chin clear white bordered posteriorly with.the dusky tipped 
buff feathers of a throat band. Broad line below eye dull black, 
lores and superciliary stripe dull white or buff. Males are apt 
to be richer colored than are females and with grayer tails, 
whiter chins, blacker throat bands and often a slight dusky 
barring on the breast. A half dozen birds in my own collection 
show the change into first winter dress. No. 883, ¢, Connec- 
ticut, Oct. 22, and No. 2044, 9, Connecticut, Oct. 5, have not yet 
entirely lost the natal down of the chin. They have recently 
lost the tenth and ninth primaries, the new ones of the winter 
dress being mere pin points. In neither of them have the two 
distal primaries pushed much beyond their follicles and in No. 
2044 the third has barely reached its full development; other- 
wise they. are in full juvenal dress. Nos. 2041, g, 2042, gd, and 
2043, %, Connecticut, Oct. 5, are further advanced, still having 
the white throats of the juvenal but with four primaries and a few 
body feathers of the winter dress. No. 6236, 9?, New York, 
Oct. 21, and: No. 6759, ¢,New York, Oct. 17,are still further 
advanced, the only remaining remiges of the juvenal dress being 
the second, third and fourth and the sixteenth to the twenty- 
fourth, together with the distal pair, as yet not fully grown. The 
winter plumage is coming in at the usual points on the body. 
first Winter Plumage, acquired by a complete postjuvenal 
moult excepting the distal pairs of primaries of each wing. 
Young birds and old become practically indistinguishable al- 
though the young bird tends to less barring below and the white 
has a buff tinge, the colors above being duller with paler edgings. 
In the male the white juvenal chin is replaced by a purer white, 
in the female by a rich buff, the sexes now being distinctly 
differentiated for the first time. I have several specimens in my 
collection completing the postjuvenal moult. No. 860, ¥ , Connec- 
ticut, Oct. 10, is in full winter body plumage, the first and second 
primaries show no evidences of growth, the third is old and the 
fourth a mere pin point, the fifth nearly grown and the rest of
