282 Tur Witson BULLETIN—Nos. 76-77. 
axillers were dropped on June 18, followed irregularly by 
the smaller feathers. Up to July 24+ the new underparts ap- 
peared devoid of yellow, but by the last of the month com- 
menced to take on the rich tint' Freshly cast primaries, sec- 
ondaries and scapulars, gathered about the nests of breeding 
birds, seem to indicate that my captive began and continued 
moulting several days in advance of the wild birds of this 
locality. 
If this species has a regular winter moult in its southern 
home, I can find no evidence of it. All spring migrants I have 
seen with the exception of one Cuban specimen taken Feb. 2, 
1906. which shows little wear, have the bleached out, well 
worn plumage similar to my captives of the same period. To 
me the dark phase is synonymous to the new, and the gray 
phase to the old, well worn plumage of the spring and early 
summer months. 
The specimens J. I!. Fleming has examined from his own 
and the Dwight collection, contain some very interesting South 
and Central American skins. An adult female, Palcaju, Peru, 
Nov. ’02, has fresh primaries and secondaries, the latter prob- 
ably the newest; all wing coverts are worn, there is a good 
deal of chestnut on scapulars and interscapulars. An adult 
male, Merida. Venezuela, Dec. 20, ’03, is almost fully adult; 
first primary is nearly full grown, but still in quill at base of 
both wings, the second primary is new as are all the others 
except the third on the right which is slightly worn; the sec- 
ondaries are slightly worn, the secondary coverts more so, a 
good deal of chestnut shows on the scapulars and back of the 
neck ; the tail feathers are nearly fresh. Adult female, Merida, 
Venezuela, Mar. 24, 03, the secondaries and tail feathers are 
worn and some chestnut 6n interscapular region. Adult 
female, Carrilla, Costa Rica, April 5, 95, the feathers of wings 
and tail very little worn, the bird practically in full plumage. 
Adult female, Boqueti Chiriqui, Panama, April 25, 03, two of 
the secondaries very much worn, the rest and the primaries 
are fresh; the chestnut on interscapular region almost worn off.
