546 NOTES ON CERTAIN INLAND : 
us in summer are much less than might be supposed, how- 
ever, from my note in the "Geology of New Jersey," p. 
116. ! 
16. Red-bellied Nuthatch (Sitta Canadensis). A careful 
observer of the birds that now (November) are enlivening 
our generally leafless trees will not fail to notice continually 
a woodpecker-like moving little bird that has as unmusical 
a note as ever fell upon one’s ear or added cacophonic va- 
riety to a harsh mixture, for verily the music of the woods 
hath now departed. Of the three birds to which these re- 
marks are applicable, we refer particularly to that named 
above. A strictly northern species, early in November by 
ones and twos they make their appearance in company with 
Sitta Carolinensis, and to the casual observer they appear to 
be one and the same. In their habits, they, with us, present 
nothing distinctive. "They number, we should judge, about 
one to twenty compared with “ Carolinensis,” and three or 
four per cent. remain during the summer. The locality of 
their nests and breeding habits are generally the same as in 
S. Carolinensis. 
17. Black-throated Bunting (Zuspiza Americana). Al- 
though abundant during the summer in Pennsylvania, less 
than one hundred miles from the state line (Delaware River), 
we had never, up to the end of the summer of 1867, been 
able to see these birds later than May, until they appeared 
in numbers in September. In the spring of 1868, and again 
during the past spring and summer, we found in various lo- 
ealities colonies of them breeding in low bushes, several 
nests being found in one field. We believe that for some 
reason we have not ascertained, they have annually left the 
state to breed and then reappeared. They are now with us 
(November) and we think that a féw remain during the 
winter. 
18. Rusty Black-bird (Scolecophagus ferrugineus). Dur- 
ing the summers of ’67, ’68 and '69, these birds have been 
quite abundant about Trenton, New Jersey, associating with
