 birds, by these tables, are mourning-doves, meadow-larks, and 

 cowbirds, since they occur in meadows 7 times, 12 times, and 15 

 times as commonly as English sparrows; while pastures appar- 

 ently afford a common meeting ground for all the birds of this 

 list of most important species, the coefficient of the blackbird — 

 the most frequent pasture bird — being less than three times 

 that of the English sparrow, the least frequent of these birds in 

 pastures. 



Numerous questions of cause, effect, and controlling con- 

 dition are suggested by these data, some of them readily an- 

 swerable and others doubtfully so, but the discussion of ecologic- 

 al problems may best be postponed until the data here present- 

 ed may be brought into comparison with those oljtained from 

 other trips, made at other seasons and in other parts of the state.
