SOME NOTABLE BIRD-CENSUS RESULTS. 



Geneva, X. Y. — An extensive series of counts from the vicinity of 

 Geneva, N. Y., for the three years 1916 to 1918, made by Otto Mc- 

 Creary, seems worthy of rather detailed presentation. (See Table 4.) 

 Comparison of the results obtained here with those of Xew York 

 State as a whole for the same years indicates to some extent how 

 sample areas, if representing the average conditions for their respec- 

 tive localities, make generalizations possible, but shows also that 

 many localities are needed to determine the final averages. When 

 considering the results, it is to be remembered that the figures from 

 the State as a wholo include those from Gpneva and that all the 

 present dam deal wim land which is or might i>e farmed, no reports 

 having been received from the mountain regions of the Adironaacks 

 and Catskills.
