Observations on the shifting range, migration, and economic value of the 

 bobolink, W. L. INIcAtee (Auk, 36 (1919), No. 3, pp. 430, 431).— This is a brief 

 account based upon investigations of the present economic status of the bobolink 

 carried on from New Jersey south to Florida, inclusive, from August to Octo- 

 ber, 1918. The inclusion of this bird among those protected by the recently 

 consummated treaty with Canada for the protection of migratory birds led to a 

 demand for this information. Attention is first called to the fact that the 

 trend of the bobolink's breeding range is to the northwest, British Columbia 

 now being the western limit. The main fall migration route seems to converge 

 into a funnel not far south of the breeding range, through which the birds pour 

 in a narrow stream along the coast of southern North Carolina, South Carolina, 

 and Georgia, expanding again so as to cover tlie whole breadth of peninsular 

 Florida. 



The once decadent rice industry of the South Atlantic States stimulated by 

 war prices resulted in an acreage in 1919 probably in excess of 6,000. The 

 destruction of this by the bobolink or ricebird averages about 25 per cent, a 

 money loss for the rice alone probably in the neighborhood of $150,000. As a 

 result of the investigation, an order has been issued by the U. S. Department 

 of Agriculture permitting the killing of the bobolink in Pennsylvania, New 

 Jersey, Delaware, IMaryland, and the District of Columbia from September 1 

 to October 30, inclusive, and in the States from Virginia to Florida from August 

 16 to November 15.
