eral more are extirpated ; three are believed to be hybrids ; five 

 or six are linown or believed to have been introduced ; of about 

 375 remaining, 165 are popularly distinguished as water-birds and 

 210 are land-birds. Of these, 29 water-birds and 37 land-birds are 

 accidental wanderers from various points of the compass, chiefly 

 from the West and South ; 30 more are of decided rarity, leaving 

 about 280 species of somewhat regular occurrence, of which about 

 three-sevenths are water-birds, a relatively large proportion due 

 to the coastwise situation." 



These 390 species and subspecies are arranged in systematic se- 

 quence following the A. O. U. Check-List implicitly, but adding a 

 number of local or vernacular names. No attempt is made to give 

 descriptions. Relative abundance and status, as well as the times 

 of occurrence are given, and the place of occurrence is stated in 

 the case of each species. The right hand page is left blank for 

 annotations, so that the actual number of printed pages covered 

 by the List is 38. An index covers about 8 pages, and the List 

 closes with about six double pages of "Seasonal Charts," indicat- 

 ing by lines and dashes the actual times of the year when each 

 species is present. This chart is also arranged systematically as 

 to the names of the birds. While there would be some obvious 

 advantages in a chronological arrangement of the species, in the 

 order of their spring migrations, the disadvantage of not knowing 

 where to look for any given species would be great. The print and 

 paper are excellent. The List should prove of great value to stu- 

 dents of birds in the region which it covers. l. j. 



Birds in Relation to a Grasshopper Outbreak in California. By 

 Harold C. Bryant. University of California Publications in 

 Zoology, Vol. 11, No. 1, pp. 1-20. November 1, 1912. 



"An investigation into the relation of birds to a grasshopper out- 

 break was carried on at Los Banos, Merced County, California, 

 July 11 to 17, 1912. 



"Grasshoppers were found to be causing considerable damage to 

 alfalfa and vegetables. An infestation of about fifteen grasshop- 

 pers to the square yard appeared to be necessary to cause notice- 

 able damage. In the infested areas the grasshoppers were computed 

 to number from twenty to thirty to the square yard." Observa- 

 tions and the examination of stomach contents showed the fol- 

 lowing species of birds to be feeding upon grasshoppers : Agelaius 

 phosniceus californicus, Stiirnella neglecta, Euphagus cyanocephalus, 

 Icterus bullocki, Tyramnus verticalis. Lanius ludomcianus garnbeli. 

 Passer domesticm, Speotyo cumioularia hypogwa, Oxyechus vocif- 

 eriis, Bntorides virescens anthonyi, Sayoris nigricans, Otocoris
