PRELIMINARY CENSUS OP BIRDS. 11 



The census covered 58 of the 108 acres of the average farm of the 

 Northeastern States and revealed on this area a bird population of 

 69 nesting pairs, and on the remaining 50 acres it is estimated that 

 there would be about one pair to the acre; in all, 114 nesting pairs 

 to the 108 acres of farmed land. On the 46 acres of wild land exist- 

 ing for each 108 acres of farmed land it is safe to assume that there 

 would be fewer birds than on the census-covered area. 



The results of the census show that the numbers of birds are too 

 few, and it is beheved that with adequate protection and encourage- 

 ment they can be materially increased. The record for density 

 comes from Chevy Chase, Md., where 161 pairs of 34 species were 

 found nesting on 23 acres. 



This prehminary census shows that the most abundant bird on 

 farms of the Northeastern States is the robin; that the next is the 

 English sparrow; and that following these are the catbird, the brown 

 thrasher, the house wren, the kingbird, and the bluebird in the order 

 named.
