of the neck. A chick of fogata (J. Dwight, Jr., No. 5964, 9°, 
Quebec, July 1) has the remiges well developed except the two 
distal and a few proximal. ‘The tail is beginning to show as the 
rectrices push out the tufts of down surmounting them; the wing- 
coverts are well grown; and the sides of the breast are covered 
with new feathers which have also begun to appear in the ante- 
rior dorsal and lumbar regions and on the throat and crown. 
No. 5968, g, of the same brood, three days older, shows a little 
more tail and more feathers on the crown. No. 5978, ?, of the 
same brood, eight days older, shows a couple of inches of tail 
and has already begun the postjuvenal moult of the primaries, 
the eighth, ninth and tenth having fallen out. The chin, throat, 
forehead, superciliary stripes and mid-abdomen are still downy. 
JSuvenal Plumage, acquired by a complete postnatal moult. It 
is at its full development when the birds are less than three 
quarters grown, the loss of the remiges by the postjuvenal moult 
beginning very early. This plumage is similar to that of the 
adult female, but is browner with paler and less distinct barring, 
the chin white instead of buff, the rectrices more distinctly barred, 
and the remiges with wider and more mottled outer webs. There 
are no neck tufts, males and females being practically indis- 
tinguishable at this stage. A specimen of /ogata (J. Dwight, Jr., 
No. 4166, g, Quebec, July 24) is not much more advanced than 
No. 5978, but is double the size and has very little down left on 
the chin. Two other males (J. Dwight, Jr., Nos 1363 and 1364, 
Nova Scotia, August 7,) have renewed the primaries from the 
tenth outward as far as the fifth, and the body feathers also of 
the first winter plumage are appearing on the breast laterally and 
on the back. Several other specimens in the American Museum 
are at about the same stage (Amer. Mus. No. 57877, Manitoba, 
August 6, and No. 55575, Wisconsin, August 24). 
first Winter Plumage, acquired by a complete postjuvenal 
moult, except the two distal primaries. The full adult dress 
is assumed, males becoming distinguishable from females by 
the more prominent black neck tufts now acquired for the first 
time. A specimen of ‘éogata (J. Dwight, Jr., No. 224, 9, New 
Hampshire, Sept. 10) has assumed this plumage except for the 
head and throat, and the third and fourth primaries, while buff-
