22 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



C. tristis. Goldfinch. Strange to say, I have never found its nest, but I am sure that it 

 breeds. 



S. socialis. Chipping Sparrow. Very common. 



M. melodia. Song Sparrow. Common. 



M.palustris. Swamp Sparrow. I perhaps found it once, but as the nest was talcen 

 before / saw the bird, I consider it doubtful. 



G. ludoviciana. Rose-breasted Grosbeak. At least one pair breeds every summer. 

 Have found the nest oftenest in birches, but also in oaks (at a height of thirty feet) and in 

 apple trees. 



C. cyanea. Indigo-bird. Have found but two nests and these I found in the last two 

 years, although I have seen the bird every year and have looked very carefully for its nest. 



ICTERIDjE. 



M. pecoris. Cowbird. I do not often see the bird, but its presence is made known by 

 its eggs. 



A . phceniceus. Red-winged Blackbird. None breed now, though eight years ago there 

 were quite a number of them. The last nest I found -was in 1870. 



/. baltimore. Baltimore Oriole. Very common in the woods, though most of them do 

 not breed in them, but in the neighboring gardens and streets. I find some nests every year. 



Q. versicolor. , Purple Grackle. The commonest bird, though not as plenty, I think, as 

 they were two or tliree years ago, when they used to breed in all the pines of which there are 

 a great number, but now, owing to the constant robbing of their nests, they breed only in the 

 pines that grow close to the house. This is the only place in Cambridge where they breed in 

 such large numbers. 



CORVIDjE. 



C. americanus. One or two pairs breed every year. 



TYRANNIDjE. 



Coniopus virens. Wood Pewee. Two or three pairs every year. 



Trochilid^. 



T. colubris. Ruby-throated Hummingbird. I have not found the nest, but the bird is 

 constantly darting to and fro and probably breeds. 



CuCULIDiE. 



C. americanus. Yellow-biUed Cuckoo. Have found but one nest, though the bird is to be 

 seen every year. 



C. erythrophthalmus. Black-billed Cuckoo. More common than C. americanus, though 

 for the last two years I have had greater difficulty in finding a nest than in former years. 

 This grove seems, however, to be the grand hymeneal temple for all the birds of the species in 

 the neighborhood, for they are very plenty in the courting season. 



PiCIDiE. 



P.pubescens. Downy Woodpecker. Not common, though there is at least one pair 

 every summer.
