In Family Icteridz, though we have not the same type of plumage throughout, the 
arranagement may be as follows: 
1. Sturnella magna, 
2. Scolecophagus ferrugineus, 
3. Dolichonyx oryzivorus, 
4. Ageleus pheniceus, 
5. Molothrus ater, 
6. Icterus baltimore, 
7. Icterus spurius, 
8. Quiscalus purpureus, var. enews. 
The first exhibits the streaked type of plumage in both sexes, and is nearly resident 
with us. The second, the only species breeding exclusively to the north of us, presents 
in the fall a change of plumage similar to that of the young. The third, whose south- 
ern breeding range is with us, presents a highly developed plumage in the male while 
the female resembles the young, retaining the streaked plumage, to which the male re- 
turns in the fall. The fourth, presents the same difference in sex as the third, except 
that the male retains its spring pattern of plumage permanently. In the fifth 
species the male and female have both outgrown a streaked plumage in the young, but 
the male acquires a higher developement of plumage than the female, and breeds both 
to the north and south of us. In the two Orioles the males differ from the females in 
brighter colors and more definite pattern, and undergo no marked change of plumage in 
the fall. The Orchard Oriole is more southern in its breeding range than the Balti- 
more. The last species presents but little difference in the plumage of the male and fe- 
male, and the young, as is also the case with the Orioles, is not streaked. 
We have now considered the relations existing between young and old and different 
species cf birds of the spotted, barred and streaked type of plumage, using for this pur- 
pose the largest families in which these types are especially noticeable; fortunately they 
are the larger families of the Oscines. I have made no mention of the large family 
Sylvicolide, for the reason that it presents different types of plumages in different genera, 
and, among those of streaked pattern, few birds which afford comparison by 
reason of marked differences in southern breeding limits. Of the Sylviidmw, Parida, 
Sittide, Tanagridw, Vireonide, Ampelidz and Corvide, it may be said that they possess 
no pattern of coloration, the body plumage being generally of uniform, dull or neutral 
tint in which the young and adult resemble each other. The same is true of sub-order 
Clamatores. Family Hirundinide presents no marked variations to confirm or
