However, left-over feathers elsewhere furnish proof of ma- 
turity in three instances. 
A general renewal is progressing in the twenty-two Cane: 
birds. Seven (two of the 7th, one each of the 11th and 18th, 
two of the 23rd, and one of the 30th) have doffed all of the old 
primaries, but in no case has a new distal primary attained full 
growth. Two birds of the 30th have kept the outer two old 
primaries while three of the 3rd have retained'only the first, 
further illustrating the absence of uniformity in the progress 
of the moult. 
Of the thirteen November examples, five have failed to cast 
the old primaries as follows: One of the 13th, the first on the 
left wing; one of the 6th and two of the 15th, the first; one of 
the 22nd, the outer three. In the other eight examples new 
primaries have replaced the old. The first, however, has not 
overtaken the second, save in a single instance on the left wing. 
Growing feathers occur to some extent in all of the Decem- 
ber specimens, in nine of them even in the tail. In only four 
(one each of the 6th and 14th and two of the 26th) does the 
first primary still fall far short of the second. 
Most of the January birds are in good plumage, although 
they display, with two exceptions, more or less replacement 
under way on the body and in some cases on the head and neck. 
Three are behind all the others in the rehabilitation of the 
wings and tail. One of these tardy individuals, shot January 
2, 1908, has retained ten old rectrices and the old distal 
primary. Another, taken January 3, 1913, has the distal 
primary about three fourths grown and six rectrices in various 
stages of development. In the remaining one, obtained Janu- 
ary 2, 1908, the distal primary equals the second, and six 
rectrices are being renewed. 
February specimens also show moult. One taken on the 
25th is replacing three rectrices and numerous feathers on the 
upper and lower parts. Another of the 25th is renewing fewer 
feathers on the head, neck, and body and but two rectrices. 
Most of the others exhibit some growing feathers above and 
below. Already disintegration is very apparent. 
March and April specimens show increasing wear and the 
final disappearance of growing feathers. Some of the lag- 
gards in much worn attire may be hold-overs.
