birds of that species found in that crop to the total number 

 of all birds found in the same crop. 



From Table VIIl. it will be seen that the principal roni- 

 field species at the times and places of this trip was the Eng- 

 lish sparrow, to which more than half the liirds seen in corn 

 fields belong, and that the mourning-dove and the meadow-lark 

 were the species next in abundance there — 6 per cent, and 5 

 per cent, respectively. In sfnhh/r fields the meadow-lark was 

 the most abundant species, making about a tifth of all the birds 

 seen in such fields. The ne.xt in order of abundance were the 

 mourning-dove, the English sparrow, the horned lark, and 

 the crow-blackbird, present in ratios i-anging from 9 per cent, 

 to 5 per cent. The meadow-lark was also much the most 

 abundant bird on fields of ijoiiikj irlicat, where it made 45 per 

 cent, of all the birds seen; and the horned lark and the gold- 

 finch were next to this in nunilier. one third and one tifth as 

 great respectively. The principal pasfurc species were the Eng- 

 lish sparrow (24 per cent.) and the crow-blackbird (20 percent.), 

 with the crow, the cowd)ird, the horned lark, and the meadow- 

 lark following in numbers ranging from a third to aljont a fifth 

 the number of the sparrows. In incitdoirs, on the other hand, 

 the meadow-lark and the cowbird were in the lead, each 18 per 

 cent, of all the meadow birds identified, and the English spar- 

 row and the mourning-dove were about half as numerous. On 

 f(dl pJow'uig moYQ t\vA\\\m\i the birds were horned larks, and 

 the only other abundant species were the crow (18 per cent.) 

 and the English sparrow (13 per cent.). In the small num- 

 ber of orcliards traversed the English sparrow was at this time 

 much the most abundant bird (51 per cent.). The other com- 

 mon species were the goldfinch (8 per cent.), the field-.sparrow 

 (4 per cent.), and a few passing migrants — the myrtle warbler 

 and the white-throated sparrow, for example. (See Table V.)

E)i(jli.-iJi Siiarro/rit. — From these tables we leaim that about 

 two thirds of the English sparrows were in corn fields and pas- 

 tures, and in about equal numbei's in each; that approximately
