Farm and Orchard Surveys. 



Another suggestion of a similar nature would apply to rural areas, farm 

 and orchard surveys, etc. In this connection attention is directed to an 

 article in Bird-Lore for March- April, 1916, by Gilbert Grosvenor, editor 

 of the National Geographic Magazine, who writes about the bird life on his 

 farm in Montgomery County, Maryland, about ten miles from Washington. 

 The article is entitled "The World's Record for Density of Bird Popula- 

 tion." This Mr. Grosvenor claims for his farm. He found fifty-nine 

 pairs of birds with young or eggs in the nest in one acre adjacent to the 

 house and barns on his farm and this, he says, is the highest number of 

 land birds inhabiting one acre that has ever been reported to the Depart- 

 ment of Agriculture or to any Audubon Society. The details of this census 

 are presented below : 



(Only pairs whose nests were located with young or eggs 

 in them are counted). 



Flicker 1 pair 



Bluebird 1 pair 



Yellow Warbler 1 pair 



Orchard Oriole 2 pairs 



Catbird 2 pairs 



Song Sparrow 1 pair 



Chipping Sparrow 2 pairs 



Phoebe 1 pair 



House Wren 14 pairs 



Robin 7 pairs 



Kingbird 1 pair 



Martins 26 pairs 



Total 59 pairs 



English Sparrows 



Our members are invited "to go after" Mr. Grosvenor's record. They 

 will doubtless have "to go some" to surpass it but it is worth trying. The 

 reports from all such efforts will make interesting reading in the Autumn 

 Bulletin. It might be well to profit by Mr. Grosvenor's experience which 

 he freely gives in the article quoted. (If you haven't it, send 20 cents to 

 Bird-Lore, Harrisburg, Pennsylvania, for the March- April number or, 

 better still, send a dollar and receive the regular issues of the magazine
